RANUNCULACEAil. (1) Coptis japonica Mak. Berberine, palmatine, columbamine, coptisine, worenine. [Pg.328]

Worenine. This alkaloid, also obtained by Kitasato from Coptis japonica was isolated as the tetrahydro-base, C,oHjg04N, which crystallises from alcohol in colourless prisms, m.p. 212-3°, and is oxidised by iodine in alcohol to worenine iodide, yellow crystals from which worenine chloride, thin orange-yellow prisms, m.p. 295° (dec.), can be obtained. Tetrahydro-worenine behaves as a tertiary base, contains methylenedioxy- but no methoxyl groups, and its absorption spectrum closely resembles that of tetrahydrocoptisine from which it differs in empirical composition by. CHj. Worenine is, therefore, represented by (XXX), the alternative position (a) for the methyl group being untenable, since a-methyltetra-hydrocoptisine obtained by Freund s method is not identical with... [Pg.344]

Most other alkaloids shown to have AChE inhibitory activity have been isolated from plants used in traditional medicine. Coptis chinensis Franch has been used in TCM for several conditions including age-related cognitive and memory decHne. Some alkaloids found in this species e.g. berberine (43), coptisine (44) and palmatine (45) are reported to also be antiChE. Coptis chinensis extract improved a scopolamine-induced learning and memory deficit in rats and this is likely to be due to the alkaloids present thus raising ACh levels. Berberine (43) has been shown to selectively inhibit AChE compared with Bu ChE and it has been shown to improve scopolamine-induced amnesia in rats. ... [Pg.400]
