상기생의 트라이테르펜 및 페놀성 성분

Triterpenes and Phenolic Constituents from Viscum album L.

The phytochemical study of Viscum album (Loranthaceae) led to the isolation of twelve compounds, lupeol (1), betulonic acid (2), betulinic acid (3), termitic acid (4), ursolic acid (5), β-sitosterol (6),α- spinasterol (7), oleanolic acid (8), 5- hydroxy-1-(4'- hydoxyphenyl)-7-(4"-hydroxyphenyl)-hepta-1-en-3-on (9), 2'- hydroxy- 4',6'-dimethoxychalcone-4-0-glucoside (10), 2'-hydroxy-4',6'-dime thoxychalcon e-4-0-[apio-syl(1-> 2)]glucoside (11) and sringin (12). Their structures were established by chemical and spectroscopic methods. The cytotoxicity of the isolated compounds was evaluated by sulforhodamine B assay against five cultured human tumor cell lines.
