Initial Studies on Alkaloids from Lombok Medicinal Plants

The method of alkaloid testing followed the procedure of Culvenor and Fitzgerald . In the procedure, finely ground plant material is rapidly extracted with ammoniacal chloroform (CHCl 3) or dichloromethane (CH 2 Cl 2). After filtration, the solution is extracted in turn with aqueous sulphuric acid (0.1M, H 2 SO 4).

A rapid screening test for lupin alkaloids

The alkaloid screening tests currently in use (Culvenor & Fitzgerald 1962; Raffauf 1962) were developed to test for alkaloid-bearing plants and are not suited for screening low-alkaloid-content lupin seeds. We have developed a rapid screening test for lupin alkaloids that can be used in a screening

Aug 09, 2010· As part of our studies on Bhutanese medicinal plants we analysed Aconitum orochryseum Stapf. for alkaloids (Wangchuk et al., 2007).Three new hetisine-type diterpenoid alkaloids, orochrine, 2-O-acetylorochrine and 2-O-acetyl-7α-hydroxyorochrine, together with the two known alkaloids atisinium chloride and virescenine, were isolated from the aerial parts of this plant.

Additionally, there were large genetic components to both growth and an individual's growth response to dietary alkaloid. These results suggest that while genetic variation in performance on alkaloid-rich diets exists, modulation of intake rate by caterpillars may be an important mechanism to reduce effects on the growth and fitness of individuals.
