J Asian Nat Prod Res. 2014;16(5):549-53. doi: 10.1080/10286020.2014.914503. Epub 2014 May 2.

Abstract

Phytochemical investigation on the stems of Trigonostemonheterophyllus led to the isolation of a new lariciresinol-based lignan glycoside, trigonoheteran (1), together with a known lignan glycoside, aviculin (2). Their structures were elucidated by spectroscopic methods including 1D and 2D NMR (HMQC, (1)H-(1)H COSY, HMBC, and NOESY).

Keywords: Euphorbiaceae; Trigonostemonheterophyllus; lignan glycoside; trigonoheteran.
