ISOLATION AND STRUCTURE ELUCIDATION OF SOME COMPOUNDS FROM THE N-HEXANE EXTRACT OF Clematis buchananiana Buch-Ham.ex DC.

Abstract

Four compounds including β-sitosterol (1), friedelan-3-one (friedelin) (2),
lupenone (3) and daucosterol (4) have been isolated from the n-hexane extract of
the leaves of Clematis buchananiana Buch-Ham.ex DC. collected in Lao Cai Provice,
Vietnam. The structures of these compounds have been identified based on
Nuclear Magnetic Resonance (NMR) and comparison with spectral data published
in the literature. All four compounds were isolated from Clematis buchananiana
Buch-Ham.ex DC. for the first time.
