Bidens Asteraceae

Perhaps the most noteworthy aspect of the flavonoid study, however, was the high level of variation exhibited across the range of collections. Simply put, there was no relationship between taxonomic position and flavonoid profile. Differences between individuals within the same population (even adjacent plants ) often exceeded differences between other pairs of taxa. The level of variation present within this group of taxa represents one of the most extreme cases of flavonoid variation in the present author s experience [see Bohm (1987) for a review of flavonoid variation].

An example of Asteraceae reported to inhibit COX is Cichorium intybus L., or chicory (17). In Asia, Chrysanthemum sinense Sab. (Chrysanthemum morifolium Ramat) and Bidens bipinnata L. are used as anti-inflammatories on account of their likely ability to inhibit COX. [Pg.34]

The arylacetylene phenylheptatriyne (Phe—C=C—C=C—C=C—CH 3) from Bidens, Dahlia and Coreopsis species (Asteraceae) has phototoxic antimicrobial activity as have 5-(3-buten-l-ynyl)-2,2 -bithienyl (thiophene—thiophene—C=C—C=CH2) and the cyclic disulfide acetylenes thiarubrine A (C3—(C4,S—S)—C6) and thiarubrine B (Cj-(C4,S-S)-C3). The photoactivation of acetylenes derives from light absorption by these conjugated systems and ready reaction with oxygen to form reactive intermediates. [Pg.47]

Bidens pilosa L. [chuchuza, black jack] (Asteraceae) leaves are for stomachache. The leaf contains alkaloids, flavonoids, glycosides, polyphenols and steroids (15). The leaves are also eaten as a vegetable (23). [Pg.35]
