OBJECTIVE: To study the constituents from the root of Liriope platypgylla. METHODS: Six chemical constituents were isolated from the chloroform fraction and n-BuOH fraction from EtOH extract of Liriope platyphylla. RESULTS: Their structures were elucidated as beta-sitosterol-3-O-beta-D-glucopyranosile(I), palmic acid (II), ruscogenin (III), LP-C(IV), LP-D(V), 25 (S) -ruscogenin 1-O-beta-D-xylopyranoside-3-O-alpha-L-rhamnopyranoside (VI), respectively. CONCLUSION: All these compounds are isolated from this plant for the first time.
