Seasonal variation of the chemical constituents from Croton species.
The terpenes, sterols, alkaloid (glaucine) and alpha-tocopherol show seasonal variation for Croton hemiargyreus hemiargyreus and Croton echinocarpus. The amounts of triterpenes are higher during the tropical summer and in most samples the major sesquiterpene was characterized as caryophyllene. The seasonal variation of glaucine showed a maximum between June and October for C. hemiargyreus, and ...
متن کاملPhytochemical constituents of Artemisia stolonifera.
Repeated column chromatographic separation of the CH2Cl2 extract of Artemisia stolonifera (Asteraceae) led to the isolation of a triterpene (I), a sesquiterpene (II), two aromatic compounds (III and IV) and a benzoquinone (V). Their structures were determined by spectroscopic means to be simiarenol (I), (1S,7S)-1beta-hydroxygermacra-4(15),5,10(14)-triene (II), 3'-methoxy-4'-hydroxy-trans-cinnam...
متن کاملSeasonal variation in chemical composition of the Indian mackerel (Rastrelliger kanagurta) from Karachi Coast
The chemical composition variations of the Indian mackerel (Rastrelliger kanagurta) from Karachi coast were investigated seasonally over the period of one year (2004-2005). Moisture, crude protein, fat and ash contents varied from 70.11-74.41%, 16.02- 20.09%, 3.0-12%, and 0.89-1.35% respectively. The seasonal data indicated that the main fatty acids of the total lipid were C16:0, C16:1, C18:0,...
