Cyclocarya paliurus(Batalin)Iljinskaja,as a unique and rare monocotyledonous plant in Southern China,is a promising and economical Chinese herbal medicine and functional food.People have conducted a number of research on C.paliurus because of its rich triterpenoids.However,no comprehensive review has illustrated the composition and pharmacological activity of triterpenoids from C.paliurus.This review summarizes 177 triterpenoids from different parts of C.paliurus.The structures of compounds were elucidated,and their biosynthesis was inferred.The biological activities of compounds and triterpenoid-rich extracts,including anti-diabetes,antihyperlipidemia,anti-inflammatory,anticancer or cytotoxicity,antioxidation,etc.,were discussed.C.paliurus can be an important and valuable supplement to the food market.This review provides a reference for the further research and application of C.paliurus triterpenoids in the fields of foods and pharmaceuticals. 展开更多

In this study,we employed a combination of genome mining and heteronuclear single quantum coherence(HSQC)-based small molecule accurate recognition technology(SMART)technology to search for fernane-type triterpenoids.Initially,potential endophytic fungi were identified through genome mining.Subsequently,fine fractions containing various fernane-type triterpenoids were selected using HSQC data collection and SMART prediction.These triterpenoids were then obtained through targeted isolation and identification.Finally,their antifungal activity was evaluated.As a result,three fernane-type triterpenoids,including two novel compounds,along with two new sesquiterpenes and four known compounds were isolated from one potential strain,Diaporthe discoidispora.Their structures were elucidated through analysis of high-resolution electrospray ionization mass spectrometry(HR-ESI-MS)and nuclear magnetic resonance(NMR)spectroscopic data.The absolute configurations were determined using single-crystal X-ray diffraction analysis and electron capture detector(ECD)analysis.Compound 3 exhibited moderate antifungal activity against Candida albicans CMCC 98001 and Aspergillus niger. 展开更多

Gentianopsis barbata(G.barbata)represents a significant plant species with considerable ornamental and medicinal value in China.This investigation sought to elucidate the primary constituents within the plant and investigate their pharmacological properties.Fifty triterpenoids(1-50),including nine previously undescribed compounds(1,2,7,10,20,28,29,37,and 41)were isolated and characterized from the whole plants of G.barbata.Notably,compounds 1 and 2 exhibited the novel 3,4;9,10-diseco-24-homo-cycloartane triterpenoid skeleton.The isolated triterpenoids demonstrated substantial anti-inflammatory activity through inhibition of tumor necrosis factorα(TNF-α)and interleukin-6(IL-6)cytokine secretion in LPS-induced RAW264.7 macrophages,and hepatoprotective effects by preventing tertbutyl hydroperoxide(t-BHP)-induced oxidative injury in HepG2 cells.These results demonstrate both the presence of diverse triterpenoids in G.barbata and their therapeutic potential for inflammatory and hepatic conditions,providing scientific evidence supporting the clinical application of this traditional Mongolian medicinal plant. 展开更多

A reversed-phase high performance liquid chromatography (RP-HPLC) method with diode array detector (DAD) has been established to simultaneously determine six bioactive compounds in the roots ofllex pubescens, namely tortoside A, (+)-syringaresinol, ilexsaponin B3, ilexsaponin A1, ilexsaponin B1, ilexgenin A. The RP-HPLC assay was performed on a reversed-phase C18 column with a gradient elution. The mobile phase consisted of acetonitrile and water containing 0.1% (v/v) phosphoric acid. The flow rate was 1.0 mL/min and the detection wavelength was set at 210 nm. The six marker constituents were separated well with good linearity (r2〉0.9996), precision, stability and repeatability. The overall recoveries were in the range of 99.00%-104.52%. Cluster analysis was employed to analyze 15 batches of samples. The result indicated this method provide an efficient way to perform quality control as well as a scientific rationale for the Geo-authentication of I. pubescens. 展开更多
