cytellin and acteoside

To study the chemical constituents from the leaves of Acanthus ilicifolius.. The compounds were isolated by silica and gel column chromatographic methods and identified by spectoscopic analysis. The anti-influenza virus activities of these compounds were obtained by measuring the neuraminidase activity of influenza virus.. Five compounds were isolated and their structures were identified as blepharin(1), acteoside(2), isoverbascoside(3), daucosterol(4), and 3-O-β-D-glucopyranosyl-stigmasterol(5).. All the compounds are isolated from the leaves of Acanthus ilicifolius for the first time, and compounds 1 ~ 3 exhibit the anti-influenza virus activities.

From the methanolic extract of the roots of Clerodendrum philipinum, a new rearranged abietane diterpene (1) and eight known compounds were isolated by various chromatography methods. Their structures were identified by means of spectroscopic methods, including 1D- and 2D-NMR, as 17(15-->16),18(4-->3)-bisabeo-11,12,14,16-tetrahydroxy-3,5,8,11,13,15-abietahexaen-7-one (1), binankadsurin A, clerodenoside A, martynoside, acteoside, isoacteoside, astragalin, p3-sitosterol, and daucosterol. Binankadsurin A was found for the first time from a Clerodendrum species.
