Chromone and chromanone glucosides from Hypericum sikokumontanum and their anti-Helicobacter pylori activities

Phytochemistry. 2009 Jan;70(1):141-6. doi: 10.1016/j.phytochem.2008.11.006. Epub 2008 Dec 31.

Abstract

Chromone glucosides, takanechromones A-C (1, 2 and 5) and chromanone glucosides, named takanechromanones A and B (3 and 4), were isolated from the methanolic extracts of Hypericumsikokumontanum together with 27 known compounds. Their structures were established based on spectroscopic evidence. The isolated compounds and some chromone derivatives were assayed for antimicrobial activity against Helicobacter pylori and cytotoxicity against human cancer cell lines.
