Phytochemical constituents from the florets of tiger grass Thysanolaena latifolia from Nepal

Abstract

Phytochemical investigation on the florets of Thysanolaena latifolia leads to the isolation of a new compound 6″-O-acetylorientin-2″-O-α-L-rhamnopyranoside (1), named amrisoside and other 34 known compounds. The chemical structures of the compounds were determined from the interpretation of spectroscopic data including NMR, MS, and IR. This is the first report of phytochemical constituents from the monotypic genus Thysanolaena.

Keywords::

• amrisoside
• C-glycosylflavones
