Zhou and its relatives. [Method] The morphological characteristics of the mature seed-like fruits of Salvia shandongensis and its three congeners, S. miltiorrhiza, S. miltiorrhiza f. alba and S. bowleyana, were comparatively observed using both optical microscope and scanning electron microscope. [Result] The results showed that there were distinct differences in the shape, size and exine sculpture of the seed-like fruits of the four Danshen congeners： the seed-like fruits of S. shandongensis that were elliptical and had areolate sculpture with subquadrangular convex meshes as well as densely filamentous transverse lines were easy to be distinguished from those of S. miltiorrhiza Bge., which were broadly elliptical and had reticulate sculpture with subquadrate concave meshes. The seed-like fruits of S. bowleyana were fusiform and their ektexine had reticulate sculpture with polygonal meshes, which were slightly convex at the center, which are obviously different from those of S. shandongensis. [Conclusion] This study first accumulates data of the seed-like fruits of S. shandongensis, which provides important bases for establishing its taxonomical status and studying its germplasm. The morphological characteristics and reticulate sculpture on ektexine of the seed-like fruits S. miltiorrhiza Bge. are consistent with the previous report. The results in this study not only provide references for uncovering the genetic relationships between S. shandongensis and S. miltiorrhiza Bge., as well as the interspecific classification and identification. In addition, this study also provides new scientific proofs for the identification of Danshen species and their introduction and cultivation, genetics and breeding.展开更多

In the present study, a Shimadzu CLC-ODS column(150 mm x 6 mm, 5 μm) was utilized and 0.5% formic acid (A) and acetonitrile (B) were used forgradient elution at a total flow rate of 0.8 mL· min^(-1). All calibration curves showed goodlinear regression ( r > 0.999) within test ranges. Extraction was conducted by refluxing methanol(10 mL) with dried herb (0.5 g) for 1.0 h.The assay was simple, convenient and reproducible. Theproposed method was successfully applied to the determination of nine major constituents in thirteenSalvia. species and the results showed that the contents of Salvia components vary in differentspecies and origin. Tanshinone was hardly detected in S. yunnanensis and S. prionitis, thereforethey are not suitable for clinical use as Danshen.展开更多

Five components(10 μmol/L)were shown to inhibit superoxide anion generation by xanthine─xanthine oxidase system. It was also demonstrated that six components( 100 μmol/L) prevented H_2O_2─induced hemolysis and MDA fonnation in mouse erythrocytes.The effects of Sal A, Sal B, Sal C and Ros A were dose dependent. In Langendorff rat heart, pretreatment with Sal A 20μmol/L significantly prevented MDA production induced by 30 min reoxygenation after 45 min anoxia.The results indicated that there were also other potent antioxidant componentts in Salvia milliorrhiza besides Dphl and Pal. The protection of Sal A against myocardial anoxiareoxygenation inury may be mainly ascribed to its oxygen free radical scavenging activity.展开更多

[Method]Organic solvent method was adopted to extract tanshinone from S. miltiorrhiza dregs and TLC was used to determine the optimum extraction solvent. The components of tanshinone were measured with HPLC. [Result]Ether was the best solvent to extract tanshinone from S. miltiorrhiza dregs. After water immersion,dry dregs of S. miltiorrhiza and Panax notoginseng were extracted with ethanol to obtain fat-soluble extracts. Then with ether as the solvent for Soxhlet extraction,the yield of crude tanshinone was 2.17%. The HPLC detection showed that the contents of tanshinone Ⅱ A,methylene tanshinquinone,cryptotanshinone,tanshinone Ⅰ were 3.62%,1.02%,2.56%,2.75% respectively. [Conclusion]The components of tanshinone in S. miltiorrhiza dregs were basically the same as tanshinone in medicine S. miltiorrhiza. S. miltiorrhiza dregs could be used as a kind of tanshinone resource,which has the value of development and utilization.展开更多

The...The effects of LaCl3 on the growth,photosynthetic gas-exchange characteristics,chlorophyll fluorescence,and the accumulation of tanshinones and salvianolic acids in Salvia miltiorrhiza seedlings were investigated. The results showed that the increase in photosynthesis induced by LaCl3 might be attributed to the enhanced stomatal conductance of the leaves and the increased level of the photochemical efficiency of PS II. The accumulation of tanshinone IIA and cryptotanshinone was markedly increased with the application of LaCl3 at 20 and 60 mg/L,while tanshinone I was only slightly increased. The content of salvianolic acid B was,however,decreased with the treatment of LaCl3 at 200 mg/L.展开更多

The results revealed that G. luteus fermentation could significantly improve the antioxidant activity and total phenolic content of S. miltiorrhiza. The main antioxidant constituents were characterized by spec- troscopic analysis as salvianolic acids. High-performance liquid chromatography （HPLC） quantification also showed the enhanced content of salvianolic acid B after fermentation. The present study suggests that G. luteus fermentations are effective in the S. miltiorrhiza salvianolic acids＇ enrichment process.展开更多

In this experiment, salvianolic acid B standard was used to make the standard curve. Single factor experiment and orthogonal experiment were used to study the extraction of different ethanol concentrations, reflux times and material-to-liquid ratios. The OD value of salvianolic acid compounds was measured with a spectrophotometer. The extraction rate of phenolic acid compounds under different extraction conditions was calculated through a regression equation, so as to obtain the optimal conditions for the ethanol reflux extraction process of Salvia miltiorrhiza. The experimental data can provide a reference for the ethanol reflux extraction process of salvianolic acids in the industry. According to the experiment, the extraction rate of phenolic acids in Salvia miltiorrhiza was the highest when the ethanol concentration was 60%, the reflux time was 1.5 hours, and the ratio of material-to-liquid was 1:10.展开更多

[Method] Twelve pairs of SSR primers with ideal cpSSR amplification result, good repeatability and clear amplification bands were selected for cpSSR detection and analysis of S. miltiorrhiza samples from 31 sampling locations in 25 counties of 8 provinces in China. [Result] S. miltiorrhiza shows an overall medium level in the cytoplasmic inheritance （cpSSR） and varying degrees of differences in the regions. Based on Shannon’s Information index （I） and Nei’s genetic diversity index, the cytoplasmic genetic diversity in different provinces shows a decreasing order of Shanxi, Henan, Shandong, Hebei, Sichuan, Jiangsu, Shaanxi, Anhui. Genetic variations of S. miltiorrhiza in eight provinces were found mainly among populations. Gene flow among populations with in a province is less than that among different provinces. [Conclusion] Comprehensive analysis shows that S. miltiorrhiza cultivated in genuine producing areas and traditional main producing areas are mainly introduced from the local before introduction of some foreign germplasm resources during cultivation. The exchange of S. miltiorrhiza germplasm resources exists very early among genuine producing areas such as Sichuan, Shandong and Henan, while S. miltiorrhiza germplasm resources in new producing areas are mainly introduced from genuine producing areas. However, no geographical correlation was observed in the genetic differentiation, which further reveals that there is a wide range of genetic exchange among S. miltiorrhiza germplasm resources in China, resulting from the artificial introduction from allopatry.展开更多

文摘A reverse-phase HPLC method was developed for the simultaneous separation and determination of five bioactive phenolic acids,yunnaneic acid E,rosmarinic acid,lithospermic acid,salvianolic acid B and salvianolic acid A in eight different samples of Salvia yunnanensis collected in Yunnan Province.For comparison,the sample of Salvia miltiorrhiza was included. All the samples were extracted for 60 min with 50%methanol in an ultrasonic bath.The optimal separation was achieved on a YMC-Pack Pro C18 column,with a gradient of 0.1%（v/v） phosphoric acid and acetonitrile,at a flow rate of 1.0 mL/min and at a detection wavelength of 280 nm.The separation was obtained within 65 min for five bioactive phenolic acids.All calibration curves showed good linearity（r^2〉0.999） within test ranges.The relative standard deviation of the method was less than 5%for intra- and inter-day assays.The mean recovery of the method was in the range from 97%to 104%,with RSD less than 5%.This assay was successfully applied to the quantitative determination of five bioactive phenolic acids in nine resource samples. The results showed that the developed HPLC assay was suitable for the quality control of S.yunnanensis and it can be used to differentiate S.yunnanensis from S.miltiorrhiza.
文摘Objective:This study aims to investigate the potential molecular mechanism of Salvia miltiorrhiza in treating benign prostatic hyperplasia(BPH)based on network pharmacology.Methods:Active components of Salvia miltiorrhiza were screened via the TCMSP database,and their potential targets were predicted using Swiss Target Prediction.BPH-related targets were obtained from Gene Cards and OMIM databases.Common targets between the herb and BPH were used to con-struct a protein-protein interaction(PPI)network via STRING and visualized using Cytoscape.Core targets were identifi ed,and Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were conducted(P≤0.01).Results:A total of 57 active components and 818 targets of Salvia miltiorrhiza were identifi ed.Intersection analysis yielded 458 potential targets associated with BPH.PPI network analysis revealed core targets including SRC,PIK3R1,and PIK3CA.GO enrichment analysis indicated that the targets were primarily associated with biological processes(BP)such as calcium ion homeostasis,cellular components(CC)including focal adhesions,and molecular functions(MF)such as tyrosine kinase activity.KEGG pathway analysis indicated that Salvia miltiorrhiza may exert therapeutic effects through pathways including MAPK,PI3K-Akt,and calcium signaling(P≤0.01).Conclusion:Salvia miltiorrhiza may regulate BPH through a multi-component,multi-target,and multi-pathway network,providing a theoretical basis for its clinical application.

文摘[Objective]The aim was to extract tanshinone from Salvia miltiorrhiza Bge. dregs and to determine tanshinone components. [Method]Organic solvent method was adopted to extract tanshinone from S. miltiorrhiza dregs and TLC was used to determine the optimum extraction solvent. The components of tanshinone were measured with HPLC. [Result]Ether was the best solvent to extract tanshinone from S. miltiorrhiza dregs. After water immersion,dry dregs of S. miltiorrhiza and Panax notoginseng were extracted with ethanol to obtain fat-soluble extracts. Then with ether as the solvent for Soxhlet extraction,the yield of crude tanshinone was 2.17%. The HPLC detection showed that the contents of tanshinone Ⅱ A,methylene tanshinquinone,cryptotanshinone,tanshinone Ⅰ were 3.62%,1.02%,2.56%,2.75% respectively. [Conclusion]The components of tanshinone in S. miltiorrhiza dregs were basically the same as tanshinone in medicine S. miltiorrhiza. S. miltiorrhiza dregs could be used as a kind of tanshinone resource,which has the value of development and utilization.

文摘The effects of LaCl3 on the growth,photosynthetic gas-exchange characteristics,chlorophyll fluorescence,and the accumulation of tanshinones and salvianolic acids in Salvia miltiorrhiza seedlings were investigated. The results showed that the increase in photosynthesis induced by LaCl3 might be attributed to the enhanced stomatal conductance of the leaves and the increased level of the photochemical efficiency of PS II. The accumulation of tanshinone IIA and cryptotanshinone was markedly increased with the application of LaCl3 at 20 and 60 mg/L,while tanshinone I was only slightly increased. The content of salvianolic acid B was,however,decreased with the treatment of LaCl3 at 200 mg/L.

文摘The antioxidant activities and total phenolic content of fermented Salvia miltiorrhiza with fungus Geomyces luteus were investigated. The results revealed that G. luteus fermentation could significantly improve the antioxidant activity and total phenolic content of S. miltiorrhiza. The main antioxidant constituents were characterized by spec- troscopic analysis as salvianolic acids. High-performance liquid chromatography （HPLC） quantification also showed the enhanced content of salvianolic acid B after fermentation. The present study suggests that G. luteus fermentations are effective in the S. miltiorrhiza salvianolic acids＇ enrichment process.
文摘The extraction technology of phenolic acid compounds from Salvia miltiorrhiza by ethanol reflux was studied. In this experiment, salvianolic acid B standard was used to make the standard curve. Single factor experiment and orthogonal experiment were used to study the extraction of different ethanol concentrations, reflux times and material-to-liquid ratios. The OD value of salvianolic acid compounds was measured with a spectrophotometer. The extraction rate of phenolic acid compounds under different extraction conditions was calculated through a regression equation, so as to obtain the optimal conditions for the ethanol reflux extraction process of Salvia miltiorrhiza. The experimental data can provide a reference for the ethanol reflux extraction process of salvianolic acids in the industry. According to the experiment, the extraction rate of phenolic acids in Salvia miltiorrhiza was the highest when the ethanol concentration was 60%, the reflux time was 1.5 hours, and the ratio of material-to-liquid was 1:10.

文摘[Objective] This study aimed to analyze the genetic characteristics of Salvia miltiorrhiza by using cpSSR （chloroplast microsatellites） molecular marker method. [Method] Twelve pairs of SSR primers with ideal cpSSR amplification result, good repeatability and clear amplification bands were selected for cpSSR detection and analysis of S. miltiorrhiza samples from 31 sampling locations in 25 counties of 8 provinces in China. [Result] S. miltiorrhiza shows an overall medium level in the cytoplasmic inheritance （cpSSR） and varying degrees of differences in the regions. Based on Shannon’s Information index （I） and Nei’s genetic diversity index, the cytoplasmic genetic diversity in different provinces shows a decreasing order of Shanxi, Henan, Shandong, Hebei, Sichuan, Jiangsu, Shaanxi, Anhui. Genetic variations of S. miltiorrhiza in eight provinces were found mainly among populations. Gene flow among populations with in a province is less than that among different provinces. [Conclusion] Comprehensive analysis shows that S. miltiorrhiza cultivated in genuine producing areas and traditional main producing areas are mainly introduced from the local before introduction of some foreign germplasm resources during cultivation. The exchange of S. miltiorrhiza germplasm resources exists very early among genuine producing areas such as Sichuan, Shandong and Henan, while S. miltiorrhiza germplasm resources in new producing areas are mainly introduced from genuine producing areas. However, no geographical correlation was observed in the genetic differentiation, which further reveals that there is a wide range of genetic exchange among S. miltiorrhiza germplasm resources in China, resulting from the artificial introduction from allopatry.
