From Cornus officinalis Sieb. et Zucc., bioassay-guided fractionation led to the isolation of four active tannin compounds with high effectiveness of inhibiting Hepatitis C virus NS3 serine protease in vitro. The compounds are: 1,2,3, 6-tetragalloyl-β-D-glucopyranose (1), 1,2,3,4,6- pentagalloyl-β-D-glucopyranose (2), Tellimagrandin I (3) and Tellimagrandin II(4). The four compounds could inhibit HCV NS3 protease in vitro with IC50 values of 6.98, 5.11, 7.0 and 4.8μmol/L respectively. In addition, a new iridoid glycoside (5) was also isolated from Cornus officinalis Sieb. et Zucc., which was assigned to be 7-O-butyl morroniside by spec-troscopic analysis.

In agriculture, pests are largely controlled by agricultural chemicals. The vast majority of these pesticides are synthetic compounds, some of which are based on natural products, and a few of which are synthetic versions of natural products. Pests have evolved resistance to many of the current pesticides, often by alterations in the molecular target site. Thus, pesticides with new molecular target sites and modes of action are needed.

Aim To study the chemical constituents of Buddleja lindeyana. Methods The constituents were separated and purified by different methods of chromatography, and their structures were elucidated by IR, MS and NMR. Results Three iridoid glycosides and two other compounds were isolated from Buddleja lindeyana. Their structures were elucidated to be 6-O-feruloylajugol ( 1 ), erythro-6-oxo-4′-( 3-methoxyl-4-hydroxyphenylglycol-8')-feruloylaj-ugol ( 2 ), threo-6-oxo-4′-(3-methoxyl-4-hydroxyphenylglycol-8')-feruloylajugol ( 3 ), tetra-cosanoic acid 2,3-dihydroxypropyl ester (4), and galactitol (5). Conclusion All the compounds have been isolated from this plant for the first time. Compounds 1, 2 and 3 have protective effect agains MPP+ -induced apoptosis.

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 62.2μmaol·L 1, respectively. In conclusion, compound 1 is a newly identified iridoid glycoside with moderate antioxidant activity.
