Saponin is one of major conponents in oriental medicine, which':s present in Ophiopogoneae. Saponin composition on ethyl acetate fractions from the butanolic extracts of two species, Liriope platyphylla and Ophiopogon japonicus was measured using high performance liquid chromatography (HPLC). HPLC analysis revealed that spicatoside A and B were identified in the tuber of L. platyphylla. However, spicatoside A was not identified in the tuber of O. japonicus. Related to that, it may be possible to discriminate between Liriopis and Ophiopogonis Tuber using HPLC analysis.

Spicatoside A and spicatoside B were isolated from Liriopis tuber. Spicatoside A has anticancer activity and it is composed of 1 ${\beta}$-hydroxy diosgenin and trisaccharides. Spicatoside B has the preventive effect of diabetes mellitus and also has 1 ${\beta}$-hydroxy derivatives, which is clevaged the ether linkage of F ring of diosgenin. Therefore, selective synthesis of 1 ${\beta}$-hydroxydiosgenin is required. (omitted)
