At present, 141 compounds have been isolated from Picrorhiza scrophulariiflora and P. kurroa of the Scrophulariaceae plants, including 46 iridoid glycosides, 29 tetracyclic triterpenoids, 25 phenylpropanoids, and 11 phenylethanoid glycosides. Pharmacological studies have demonstrated that they have liver-, heart-, brain-, kidney-, and nerve cells-protecting effects as well as anti-tumor, anti-inflammatory, anti-bacterial, anti-asthma, anti-diabetic, immunomodulatory, and blood lipid-lowering activities. This article reviews the chemical components and pharmacological activities of P. scrophulariiflora and P. kurroa, aiming to provide a basis for the in-depth research, development, and utilization of the two plants.

As a traditional Chinese medicinal material, Lonicera japonica has a long medicinal history. The chemical constituents of Lonicera japonica are complex, mainly including iridoid glycosides, flavonoids, triterpenes, organic acids and volatile oil. Iridoid glycosides account for a higher proportion. In addition, modern pharmacological studies have shown that the iridoid glycosides have many pharmacological activities such as antivirus, anti-inflammation, anti-tumor, liver protection and lowering blood sugar. This review intends to systematically summarize the iridoid glycosides identified from Lonicera japonica and their pharmacological activities by searc-hing Chinese and English databases, in order to provide a reference for the further development and utilization of Lonicera japonica and for the improvement of quality standards of medicinal materials.

As a large category of natural products widely present in traditional Chinese medicine, iridoid glycosides have multiple pharmacological activities. Recent researches suggest that iridoid glycosides mainly exist in the forms of original form, aglycone and a series of their Ⅰ and Ⅱ metabolites under the biotransformation effect, and their metabolites have been proved to have multiple pharmacological activities. The research progress on metabolism and metabolite activities of several iridoid glycosides would be reviewed in this article, to provide a theoretical basis for the further development and utilization of iridoid compounds and their metabolites.

Arisaematis Rhizoma included in the Chinese Pharmacopoeia is the dried tuber of Arisaema erubescens, A. heterophyllum or A. amurense in the family Araceae. This paper mainly focuses on the classification and summary of the chemical components and structures reported in recent years in the above three varieties of this medicinal material included in the pharmacopoeia, including alkaloids, flavonoids, phenylpropanoids, lignans and benzene ring derivatives, steroids and terpenes, glycosides and esters, etc. Then we reviewed the reported biological activities of these chemical components, including cytotoxicity, antitumor activity, antibacterial activity, nematicidal activity, etc. Although there have been reports on the review of the chemical composition of the medicinal material, the structure and classification of the chemical composition in these reviews are not clear enough. This review provides a basis for the later study of the chemical composition of this medicinal material, especially the identification of the chemical structures. And most of the current reviews on the biological activity of this medicinal material are mainly for the crude extract. This paper mainly summarized the biological activity of related monomer compounds and expected to lay a foundation for the development of novel high-efficiency and low-toxicity active leading compounds from Arisaematis Rhizoma.

Two cardenolide glycosides, corotoxigenin 3-O-[β-D-glucopyranosyl-(1→4)-6-deoxy-β-D-glucopyranoside] (1) and coroglaucigenin 3-O-[β-D-glucopyranosyl-(1→4)-6-deoxy-β-D-glucopyranoside] (2), were isolated from the seed fairs of Asclepias curassavica. The structures of 1-2 were determined based on the combination of the analysis of their MS, NMR spectroscopic data and acid hydrolysis. The inhibitory effects of compounds 1 and 2 on human colorectal carcinoma cells (HCT116), non-small cell lung carcinoma cells (A549) and hepatic cancer cells (SMMC-7721) were evaluated. The results showed that both compounds 1 and 2 significantly inhibited the viability, proliferation, and migration of A549, HCT116 and SMMC-7721 cells, suggesting that compounds 1 and 2 can be applied in the treatment of lung, colon and liver cancers in clinical practice. This study may not only provide a scientific basis for clarifying the active ingredients in A. curassavica, but also help to understand its antitumor activity, which can promote the application of A. curassavica in clinical treatment of various cancers.

Four new prenylflavonoid glycosides, namely koreanoside H-K (1-4), together with eleven known ones (5-15) were isolated from the leaves of Epimedium koreanum Nakai. Their structures were elucidated by 1D NMR, 2D NMR, HR-ESI-MS, IR and UV. The identification of the sugar moieties was carried out by means of acid hydrolysis and HPLC analysis of their derivatives. It is worth noting that compound 3 and compound 4 were elucidated to contain fucose and quinovose moieties, which were two extremely rare sugar units from the genus Epimedium. The anti-pulmonary fibrosis activity of the new compounds was evaluated using A549 cell line. Compounds 1, 2 and 4 showed significant anti-pulmonary fibrosis activities.

The present study was designed to investigate the non-alkaloid compounds from the leaves and stems of Vinca major cultivated in Yunnan Province, China. The compounds were isolated using chromatographic techniques. The structures were elucidated by 1D- and 2D-NMR spectroscopic methods in combination with UV, IR, and MS analyses. The 1, 1-diphenyl-2-picrylhydrazyl (DPPH)-scavenging activity of Compounds 1-7 were evaluated. One new iridoid glycoside (compound 1), together with 11 known compounds, were isolated from Vinca major. Compounds 1, 5, and 6 showed moderate DPPH-scavenging activity, with IC50 values being 70.6, 32.8, and 62.2 μmol·L(-1), respectively. In conclusion, compound 1 is a newly identified iridoid glycoside with moderate antioxidant activity.

To evaluate the effect of Tripterygium Glycosides Tablets extract in the treatment of rheumatoid arthritis( RA). Clinical trials of treating rheumatoid arthritis with Tripterygium Glycosides Tablets published by Meta-analysis were retrieved from EMbase,PubMed,Clinical Trials,Web of Science,Cochrane Library,CNKI,Wanfang,VIP,CBM and Chi CTR,and comprehensively analyzed. A total of 3 studies were enrolled,the modified Sharp score( m TSS),tender join joint erosions( JE) and joint space narrowing( JSN) of Tripterygium Glycosides Tablets group were significant superior to those of control group,including positive drugs methotrexate( MTX) and salazopyridine( SSZ)( P<0. 01). Tripterygium Glycosides Tablets had an effect in treating RA. Due to the small sample size,this study shall be verified with high-quality,large-sample-size double-blinded RCTs.

OBJECTIVETo study the antitumor activities of the triterpene glycoside colochiroside A (CA) from the sea cucumber Colochirus anceps.

METHODThe tests of antitumor activities in vitro and in vivo were applied to demonstrate the effect of CA.

RESULTThe preliminary cytotoxic assay of CA exhibited significant cytotoxic activity against 6 types cultured tumor cell lines of p388, HL60, A-549, SpC-A4, MKN-28, and SGC-7901, the mean of IC50 were (3.61 +/- 0.55) mg x L(-1). The preliminary antitumor assay of CA indicated that this saponin exhibited high inhibiting activity against the H22 live cancer and the S180 sarcoma cells in mouse. The inhibition ratio to H22 liver cancer were 34.8%, 43.9% and 52.2%, while the ratio to S180 sarcoma were 36.4%, 70.0%, the immunoregulatory founction study indicated CA has not significant effect on the developments of thymus and spleen.

CONCLUSIONThe saponin CA exhibited remarkable antineoplastic activities in vitro and in vivo, and could not reduce the immunoregulatory founction of mice.
