title: [Studies on chemical constituents of Liriope platyphylla].
abstract: Seven chemical constituents were isolated from the CHCl3 fraction and n-BuOH fraction from EtOH ext. of Liriope platyphylla Wang et Tang. Their structures were elucidated as lupenone (I), lupeol (II), ursolic acid (III), beta-sitosterol (IV), diosgenin (V), LP-A (VI) and LP-B (VII) respectively. Compound I, II and V were isolated from this genus of Liriope for the first time. Compound III and IV were isolated from this plant for the first time.
