title: Triterpenes from Stachyurus himalaicus var. himalaicus Hook. f. et Thoms. ex Benth.
abstract: Four triterpenes 1-4, including a new naturally occurring oleanane-type triterpene 1, were isolated by a multi-step chromatography procedure from the leaves and twigs of Stachyurus himalaicus var. himalaicus Hook. f. et Thoms.ex Benth. The structures of the compounds were elucidated by spectroscopic methods, including HRESIMS, 1H- NMR, 13C-NMR, DEPT, HMQC, HMBC and NOESY spectra. All the isolated compounds were evaluated for their in vitro cytotoxic activities against human Hela cell line.
