Brachystemols A–C, three new furan derivatives from Brachystemma calycinum

Abstract

Three new furan derivatives, brachystemols A–C (1–3), and 13 known compounds (4–15) were isolated from the EtOH extract of Brachystemma calycinum. Their structures were identified by means of spectroscopic methods. Compounds 4–13 were isolated from this plant for the first time.

Keywords:

• Brachystemma calycinum
