Objective： To study the chemical constituents of the hydrolysis of Panax notoginseng （Burk） F. H. Chen. Methods： Isolated and purified compounds by kinds of chromatography technogies and identified them by their spectral data and physico-chemical properties. Results： Eight compounds were isolated and identified. Their structures were identified as ： damrnarane-20 （ 22 ） en-3β, 12β, 25-panaxatriol （ Ⅰ ）, 20 （R） -dammarane-3β, 6α, 12β, 20, 25-pentol（ Ⅱ ）, 20（R） -dammarane-3β, 12β, 20, 25-triol（Ⅲ）, 20（S）-panaxadiol（Ⅳ）, 20（S）-proto- panaxadiol （ Ⅴ ）, 20 （R） -protopanaxadiol （ Ⅵ ）, 20 （ S ） -panaxatriol （ Ⅶ）, 20 （ S ） -25-methoxyl-dammarane-3β, 12β, 20-triol （Ⅷ）. Conclusion： Compounds Ⅱ , Ⅴ were isolated from the acid hydrolytic products of the stems and leaves of Panax notoginseng（Burk） F. H. Chen for the first time.
