haplophyllum buxbaumii/悪性腫瘍

Daurinol, a lignan from the ethnopharmacological plant Haplophyllum dauricum, was recently reported to be a novel topoisomerase II inhibitor and an alternative to the clinical anticancer agent etoposide based on a colorectal cancer model. In the present study, we elucidated the detailed biochemical

BACKGROUND The flora of Saudi Arabia is one of the richest biodiversity areas in the Arabian Peninsula and comprises very important genetic resources of crop and medicinal plants. The present study was designed to investigate the cytotoxicity and the antibacterial activities of the organic extracts

Bioassay-guided fractionation of Haplophyllum canaliculatum Boiss. (Rutaceae) extract resulted in isolation of five quinoline alkaloids: 7-isopentenyloxy-gamma-fagarine, atanine, skimmianine, flindersine and perfamine. This is the first isolation of these compounds from this endemic species. The

An efficient system for the analysis of total alkaloids extracted from the aerial parts from different species of genus Haplophyllum (Rutaceae) by HPLC on a reversed-phase column is described. The HPLC method described was validated for its specificity, linearity and precision using external

The present study focuses on eudesmin (bicyclic lignan, 0.15 % of dry leaves) and diphyllin (arylnaphthalene lignan, 0.1 % of dry roots), both isolated from H. perforatum Kar. et Kir, a Rutaceae species endemic to Uzbekistan. We first compared their specificity for cancer cells with those of

Further to a systematic chemotaxonomic study of Uzbek Haplophyllum A. Juss. plants selected on ethnopharmacological data, 14 alkaloids were screened for their cytotoxic properties. As a first selection for interesting compounds, each alkaloid was tested against two human cancer cell lines (HeLa and
