[Abstract]
Object The chemical constituents of Balanophora involucrata Hook. f. (Balanophoraceae) were studied.Methods Individual constituent was isolated and repeatedly purified on silica gel column, identified by physico-chemical constants and structurally elucidated by spectral analysis.Results From the petroleum ether and ethylacetate extracts, 8 compounds were obtained, 6 of them were identified as: ursa-12-ene-11-one-3-ol-octocosate (Ⅰ),β-amyrin hexadecanate (Ⅱ),β-amyrin (Ⅲ),lupeol (Ⅳ),β-sitosterol (Ⅴ) and?β-sitosterol glucoside (Ⅵ). Conclusion All of these compounds, with the exception of?Ⅴ, were obtained from this plant for the first time, and compound I was a new one.
