The drug consists of the dried entire plant of Viola diamantica (family Violaceae). It is used for the treatment of acute pyogenic diseases such as boil and carbuncles; also as tumor, high fever, tuberculosis and astringent hemostatic. Two flavonol glycosides have been isolated from the aerial parts of Viola diamantica and could be identifed as kaempferol 7-rhamnoside and kaempferol 3,7-dirhamnoside (bright yellow needle crystal, mp $225^{\circ}$, $C_{27}\;H_{30}\;O_4\;4H_2O$). Kaempferol 7-rhamnoside and kaempferol 3,7-dirhamnoside were first isolated from Viola diamantica.

Dwarf ginseng (Panax trifolius L.) is a member of the ginseng family (Araliaceae). which is indigenous to North America and is distributed from Southern Canada to the Northern United States. In total. nine compounds were isolated from the leaves of Dwarf gineng. Of these. four were identified as flavonoids and five were found to be ginsenosides. Two of the flavonoids were identified to be kaempferol-3. 7-dirhamnoside and kaempferol-3-gluco-7-rhamnoside. Four of the ginsenosides were identified as notoginsenoside-Fe. ginsenoside-Rd. ginsenoside-Rc and $ginsenoside-Rb_1$ The common aglycone of these ginsenosides was shown to be (20S)-protopanaxadiol. The identification of flavonoids and ginsenosides from the root. stem. leaf. flower and fruit of Dwarf ginseng was detected by Two-Dimensional Thin-Layer Chromatography (2D-TLC) and High Performance Liquid Chromatography (HPLC). The quantitation of flavonoids and ginsenosides from the root. stem. leaf. flower and fruit of Dwarf ginseng and related species such as Korean gineng (Panax ginseng C.A. Meyer) and American ginseng (Panax quinquefolium L.) was analyzed by HPLC only. Three flavonoids (Kaempferol derivatives) labelled compound 1 $(10.8\%)$, compound 3 ($2.8\%$), and compound 4 ($8.4\%)$ were found in the root of Dwarf ginseng but not found in the roots of Korean ginseng and American ginseng. This is the first time that flavonoids have been found and identified in roots of the ginseng family (Araliaceae).
