[Studies on the chemical constituents from the roots and rhizomes of Gerbera piloselloides].

To study the chemical constituents from the roots and rhizomes of Gerbera piloselloides.The compounds were isolated by silica gel column chromatography, and their structures were elucidated by means of spectral analysis.Seven compounds were identified as bothrioclinin (I), hydroquinone (II), marmesin (III), succinic acid (IV), umbelliferone (V), isoarborinol (VI) and beta-sitosterol (VII).Compound I, V and VI were isolated from Gerbera genus for the first time.
