berchemia polyphylla/二酸化ケイ素

OBJECTIVE To study the rubrofusarin glucosides from whole plants of Berchemia polyphylla var. leioclada, and their scavenging activities for 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical. METHODS The chemical constituents were isolated and purified via repeated silica gel and Sephadex LH-20 column

To study the chemical constituents from the root of Berchemia lineata (L.) DC., nine compounds were isolated from the EtOAc extract by using silica gel, RP-C18 silica gel column chromatography and preparative HPLC. Based on the spectroscopic analysis, their structures were identified as
