Lychnophora

Ultrasound-assisted extraction is a rapid technique that can also be used with mixtures of immiscible solvents hexane with methanol-water (9 1), for example, is a system used for the Brazilian plant Lychnophora ericoides (Asteraceae). The hexane phase concentrated less polar sesquiterpene lactones and hydrocarbons, while the aqueous alcohol phase concentrated flavonoids and more polar sesquiterpene lactones. [Pg.3]

A full paper on the determination of the structure and absolute configuration of the two piscicidal sesquiterpenoids buddledins A (238) and B (239) has now appeared.Buddledin A has also been isolated from another Buddleja species.In addition, the structures of buddledins C (240), D (241), and E (242) have been determined and toxicity tests have shown that the latter two are not piscicidal. Another interesting oxygenated caryophyllene derivative is lych-nopholic acid (243) from Lychnophora affinis Gardn. The structure of this compound has been elucidated by a combination of n.m.r. and X-ray spectral studies. [Pg.38]

More recently " the naturally occurring cyclopropenones 9 and 11 have been isolated from Telekia speciosa. The terpene derivative with the 7a-H, compound 9, is also found in Lychnophora passerina together with an isomer tentatively assigned as the Ip-H epimer 10 and not the eudesmane derivative 11 as initially thought. [Pg.1225]
