Methods Cytotoxicity screening of the extracts from H. hookerianum were carried to isolate and purify the chemical constituents. The chemical structures were (identified) by physicochemical properties and spectral data analysis. Results Seven compounds were isola-(ted) and (established) as quercetin (Ⅰ), luteolin (Ⅱ), apigenin (Ⅲ), hyperin (Ⅳ), astragalin (Ⅴ), hyper-(olactone) A (Ⅵ), and hyperolactone C (Ⅶ). Conclusion All the compounds are isolated from H. hookerianum for the first time. Compounds Ⅲ and Ⅴ are isolated from the plants of Hypericum Linn. for the first time.
