Abstract
The aerial part of Dianella ensifolia(L.)DC. is herb pereannial, distributed in the brushwood of the mountain below altitudes of 1500 meters. Its sap is poisonous and can not be eaten. However, the smashed mixture of its stems and roots can be directly used as medicine for treating tinea, therefore we want to study the chemical constituents of the aerial part of Dianella ensifolia.
The methol extract from the aerial part of Dianella ensifolia was concentrated to give a residue which was partitioned between ethyl acetate and water. The ethyl acetate layer was separated by column chromatography on silica gel, preparative thin layer chromatography and high performance liquid chromatography(HPLC) to give fifty-one compounds. Of these compounds, five compounds are new and two compounds are isolated for the first time from natural sources.The total compounds were classified to fifteen flavonoids, fifteen aromatics, two chromones, two chalcones, one lignoids, four triterpenoids, four steroids, and eight others.
The known compounds were identified by spectral analysis and compared with those reported in literatures or authentic samples. The structures of new compounds were elucidated by spectral evidence including 1D and 2D techniques.
