Abstract: Toricellia angulata Oliv. var. intermedia (Harms.) Hu, belonging to Toricelliaceae, is a single family and single genus plant. It is distributed in Yunnan, Guizhou, and Sichuan provinces in China as well as the Himalayas. In Chinese folk medicine, T.angulata is used to treat bone fracture, tonsillitis and asthma. It can also be used to expel wind, remove dampness and promote blood circulation to remove blood stasis (Wu, 1990). During our investigation of the chemical constituents of this plant, nine compounds have been isolated and identified as two iridoid glycosides, griselinoside (1) and 10-griselinosidic acid (2), two phenylpropanoid glycosides, syringin (3) and coniferin (4), two flavonoid glycosides, quercetin-3-O-glucoside (5) and astragalin (6), a diterpenoid, phytol (7), β-sitosterol, daucosterol, respectively. Among these nine compounds, compounds 2, 4, 5, 6, 7 were obtained from this plant for the first time.

Key words: Toricellia angulata, Toricelliaceae, Iridoid glycoside, Phenylpropanoid glycoside, Flavonoid
