opium poppy (papaver somniferum l.) has two major products: alkaloids in the capsules and the seeds.  the seed contains oil, protein, carbohydrate, moisture and mineral matters. the seed oil is rich in unsaturated fatty acids, particularly linoleic and oleic acid. remaining meals after oil extraction are the important source for animal diets. the united nations recognize turkey and india as tra...

lesser periwinkle (vinca minor l.), a member of apocynaceae, is not only an ornamental plant with lilac-blue flowers, but also a medical plant producing an important alkaloid, vincamine, found in the leaves which shows a pronounced cerebrovasodilatory and neuroprotective activity. this plant is native to northern spain, western france, central and southern europe, and caucasus. it has been rece...

A total alkaloid and two purified alkaloid extracts of Alangium vitiense were found to be oncostatic for L1210 leukemia; the total alkaloid exerted a noticeable activity, and the purified extracts exerted a borderline activity. These two purified extracts are noticeably oncostatic for two other lymphoid neoplasias in mice, P388 leukemia and Gardner lymphosarcoma. These compounds are not active ...

A procedure was developed to isolate and determine ergot alkaloid production by Acremonium coenophialum, the endophytic fungus of tall fescue. The procedure established that macerated leaf sheath or pith from inRorescence stem placed either in a liquid medium or on a corn meal-malt extract agar medium produced isolated mycelium and characteristic conidia within a 3to 3.5-week period. Once isola...

Catharanthus roseus (L.) G.Don is a plant which produces anticancer and anti-mitotic indole alkaloids. Colchicine is an anti-mitotic drug. Anti-mitotic effects of Vinca herbacea Waldst. & Kit. indole alkaloids is unknown. The study were evaluated the antimitotic effect of alkaloids of V. herbacea, Catharanthus roseus andcolchicineon mitosis and microtubule arrangement of human blood cells. In t...

The ergot alkaloids are a family of indole-derived mycotoxins with a variety of significant biological activities. Aspergillus fumigatus, a common airborne fungus and opportunistic human pathogen, and several fungi in the relatively distant taxon Clavicipitaceae (clavicipitaceous fungi) produce different sets of ergot alkaloids. The ergot alkaloids of these divergent fungi share a four-member e...

The remarkably low alkaloid content of whole tobacco shoots grown as scions on rootstocks of lowalkaloid species has been recorded by many investigators (cf. Dawson (5), James (8), and Mothes (10) for reviews). Although the data of Tso and Jeffrey (14) appeared to be in contradiction, the disagreement has since been resolved (see below). Solt (13) demonstrated that low alkaloid content in this ...

The bioactivity of Alstonia boonei De Wild leaf alkaloid was tested under laboratory bioassay against the legume pod borer, Maruca vitrata Fabricius. The alkaloid was incorporated into standard M. vitrata artificial diet at five doses [0.00 % (Control), 0.02 %, 0.05 %, 0.10 % and 0.20 %], and fed to the newly emerged first instar M. vitrata larvae in plastic wells under laboratory conditions. S...

Three novel furoquinoline alkaloid oxogeranyl ethers (1-3) and one known furoquinoline alkaloid (4) were isolated from the leaves of Boninia glabra, an endemic plant of the Bonin Islands. Their structures were elucidated on the basis of spectroscopic analysis.
