[Studies on chemical constituents from rhizome of Impatiens pritzellii var. hupehensis].
OBJECTIVE
To study the chemical constituents from the rhizome of Impatiens pritzellii var. hupehensis.


METHODS
The rhizome were extracted with methanol, isolated and purified by column chromatography on silica gel. All the compounds were identified on the basis of spectral analysis (including IR, MS, NMR) and physico-chemical characters.


RESULTS
Five compounds were identified as a-spinasterol (I), alpha-spinasteryl-7, 22-dien-3-O-beta-D-glucopyranoside (II), stigmast-7, 22-dien-3-one (III), stearic acid (IV), hentriantane (V).


CONCLUSIONS
Compound I is isolated from this plant for the first time, Compound II, III, IV, V are isolated from genus Balsaminaceae for the first time.
