Baccharis crispa

Samples of the essential oil from one of these species, B. salicifolia collected in the province of Cordoba (Argentina), together with Baccharis crispa Spreng. and Baccharis cordobensis Heering were examined [65,66], The major constituents were nerolidol (15.8%), Fig. (29), cadinol (14.7%), Fig. (30) and cubenol (8.8%) from B. cordobensis, cadinol (9.4%), Fig. (30) and germacrane D (8.8%), Fig. (31) from B. salicifolia and nerolidol (27%), Fig. (29) from B. crispa.

More recently, Frizzo et al. [69] examined the essential oil from Baccharis uncinella D. C., popularly called Vassoura lageana , which grows wild in the South of Brazil. No previous phytochemical studies have been reported concerning the composition of volatile compounds from this Baccharis species. The monoterpene profile is similar to those reported for other Baccharis, such as B. dracunculifolia and B. crispa, while the sesquiterpene... 

A number of these compounds have insect antifeedant activity. The total synthesis of the substituted c/s-decalin (26) as an antifeedant has been reported. Clerodanes have previously been detected in Salvia (Labiatae) species. The gesnerohlins A and B, obtained from S. gesneraefolia, have been assigned the structures (27) and (28) although their absolute stereochemistry was not determined. A further series of clerodanes of uncertain stereochemistry has been isolated from Baccharis species, including bacrispine (29) from B. crispa and the malonate ester (30) from B. tricuneata. ...
