Peonies (Paeonia suffruticosa (tree peony), Paeonia lactiflora (Chinese peony) and Paeonia veitchii (Chinese peony)) are traditionally used on the Qinghai-Tibet Plateau in China. Recent studies have shown that the peonies have different pharmacological activities and clinical applications. To distinguish these three species of peonies and ensure the safety and effectiveness in their use, the microscopic characteristics and chromatographic profile of their roots and the corresponding powder were studied. Plant materials sectioned and stained and the raw powder were studied with an optical microscope using standard techniques in microscopy. The results of microscopic features and TLC were described and illustrated. The three species have different microscopic characteristics and TLC profiles, which allow us to distinguish them. In fact, with the help of features semi-quantitative and qualitative, an identification key was developed in our work and illustrated with photos and a table. The aim of our work was to show that the optical microscopy and related techniques provide a achievable practicality, which can be applied without ambiguity to the authentication of species peonies.展开更多

[ Method ] The two peony varieties Huhong and Luoyanghong were treated by different water stress for determining the photosynthesis and fluorescence characteristics. [ Result ] With the aggravation of water stress, the net photosynthetic rate （Pn） and stomatal conductance （Gs） decreased, while the intercellular CO2 concentration （Ci） increased. Drought could decrease Pn, constrain gas exchange and change the daily photosynthesis. Fo of peony leaf increased and Fv/Fm decreased under water stress especially water logging, causing the inactivation of the PS II reaction center, and the chlorophyll fluorescence characters gradually recovered until afternoon. [ Conclusion] The 75% soil relative water content （SRWC） is the best condition for growth of peony. Compared with drought, water logging is more unfit for the growth of peony. For the two varieties, Huhong assumed more tolerance to drought, accordingly more adaptability.展开更多

On the day before the rats were killed, those in TGP or colchicine groups received TGP or colchicine as above from the first day of tail vein injection of human albumin. The rats in normal and model groups were only administered with the same volume of vehicle. At the end of the 16th wk, rats in each group were killed. Blood and tissue specimens were taken. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), nitric oxide (NO), content of malondialdehyde (MDA), activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-px), were measured by biochemical methods. Serum procollagen type Ⅲ (PC Ⅲ) and laminin (LN) were determined by radioimmunoassay. Liver collagen level was determined by measuring hydroxyproline content in fresh liver samples. Hepatic tissue sections were stained with hematoxylin-eosin and examined under a light microscope.RESULTS: Histological results showed that TGP improved the human albumin-induced alterations in the liver structure, alleviated lobular necrosis and significantly lowered collagen content. The antifibrotic effect of TGP was also confirmed by decreased serum content of LN and PCⅢ in TGP-treated group. Moreover, the treatment with TGP effectively reduced the hydroxyproline contentin liver homogenates. However, the level of ALT and AST increased in fibrotic rat but had no significance compared with normal control, whereas the ratio of A/G decreased without significance. TGP had no effect on level of ALT, AST and the ratio of A/G. Furthermore, TGP treatment significantly blocked the increase in MDA and NO, associated with a partial elevation in liver total antioxidant capacity including SOD and GSH-px.CONCLUSION: TGP has beneficial effects on hepaticfibrosis in rats by inhibition of collagen synthesis and decreasing oxidative stress.展开更多

文摘Natural and social cultural factors responsible for the popularization of peony in China were analyzed.Peony was favored by Chinese because of not only its beauty and fragrance,but also its implication of nobility and auspiciousness,thus it has always been a representative of Chinese mainstream culture and traditional aesthetic standards.Peony breeding and cultivation in 3 peony centers of China(Luoyang in Henan,Heze in Shandong and Pengzhou in Sichuan) were introduced as well as festivals regularly held in these centers.Status of peony in Chinese culture and its influence on modern flower tourism was introduced to more people,and help them to understand the relationship among peony,Chinese aesthetic complex and national personality.
文摘[Objective] The aim of this study was to explore the microencapsulation of peony oil. [Method] Using [5-cyclodextrin, Arabic gum and soy protein as the wall materials and by the preparation technology of peony oil through spray drying, we conducted single factor experiments and orthogonal experiment analysis of the tech- nical parameters of peony oil microencapsulation. [Result] The optimal parameters of peony oil microcapsule preparation were acquired. The ratio of three wall materials （~5-cyclodextrin, Arabic gum, and soy protein） is 3：1：2, the solid content is 35%, the ratio of core-wall material is 3：1, emulsifier dosage is 0.2%, and the embedding rate of peony oil reaches 92%. [Conclusion] This technology produced the highest em- bedding rate and it laid the foundation for further development of peony oil.

文摘AIM: To study the effects of total glucosides of peony (TGP) on immunological hepatic fibrosis induced by human albumin in rats.METHODS: Sixty adult male Sprague-Dawley rats were randomly divided into: Normal group, model group, TGP (60 and 120 mg/kg) treatment groups and colchicines (0.1 mg/kg) treatment group. On the day before the rats were killed, those in TGP or colchicine groups received TGP or colchicine as above from the first day of tail vein injection of human albumin. The rats in normal and model groups were only administered with the same volume of vehicle. At the end of the 16th wk, rats in each group were killed. Blood and tissue specimens were taken. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), nitric oxide (NO), content of malondialdehyde (MDA), activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-px), were measured by biochemical methods. Serum procollagen type Ⅲ (PC Ⅲ) and laminin (LN) were determined by radioimmunoassay. Liver collagen level was determined by measuring hydroxyproline content in fresh liver samples. Hepatic tissue sections were stained with hematoxylin-eosin and examined under a light microscope.RESULTS: Histological results showed that TGP improved the human albumin-induced alterations in the liver structure, alleviated lobular necrosis and significantly lowered collagen content. The antifibrotic effect of TGP was also confirmed by decreased serum content of LN and PCⅢ in TGP-treated group. Moreover, the treatment with TGP effectively reduced the hydroxyproline contentin liver homogenates. However, the level of ALT and AST increased in fibrotic rat but had no significance compared with normal control, whereas the ratio of A/G decreased without significance. TGP had no effect on level of ALT, AST and the ratio of A/G. Furthermore, TGP treatment significantly blocked the increase in MDA and NO, associated with a partial elevation in liver total antioxidant capacity including SOD and GSH-px.CONCLUSION: TGP has beneficial effects on hepaticfibrosis in rats by inhibition of collagen synthesis and decreasing oxidative stress.
