Structurally diverse monoterpenoid indole alkaloids from as well as their potential anti-inflammatory and anti-HIV effects.

A phytochemical investigation on the stems and leaves of caused the isolation and characterisation of a new monoterpenoid indole alkaloid, damnahainanline (), as well as seven known analogues (-). The molecular structure of was determined in the light of comprehensive spectroscopic data analyses and the known analogues - were determined comparing their experimental spectroscopic data with the reported spectroscopic data in the literature. The anti-inflammatory effects as well as anti-HIV activities of all isolates - were assessed.

[Chemical constituents from stems and leaves of Artocarpus tonkinensis and their inhibitory effects on proliferation of synovioblasts in vitro].

The chemical constituents from the stems and leaves of Artocarpus tonkinensis in Artocarpus of Moraceae were systematically studied by means of silica gel, octadecylsilyl(ODS), and Sephadex LH-20 gel column chromatographies, as well as preparative high-performance liquid chromatography(Pre-HPLC) and a variety of chromatographic separation techniques. The spectral data and physicochemical properties of the compounds were obtained from separation and compared with those of the compounds reported in the literature. As a result, 11 compounds isolated from the 90% ethanol extract of the stems and leaves of A.
