Studies on Chemical Constituents from Hyssopus Cuspidatus Boriss.

OBJECTIVE To study the chemical constituents of Hyssopus cuspidatus Boriss.. METHODS Isolation and purification were carried out by silica gel and Sephadex LH-20 column chromatographies. Compounds were identified by physicochemical properties and spectral analysis. RESULTS Seven compounds were isolated from the plant. Their structures were identified as chrysin(Ⅰ), 24-methylenecycloartanol(Ⅱ), oleanolic acid(Ⅲ), n-hexadecanol(Ⅳ), hexacosyl alcohol(Ⅴ), β-sitosterol(Ⅵ), daucosterol(Ⅶ), respectively. CONCLUSION CompoundsⅠ, Ⅱ and Ⅳ are isolated from the plant for the first time.
