The effect of pro-ecological procedures and insect foraging on the total content of phenol compounds in winter wheat.

In laboratory conditions, the effect of pro-ecological procedures (application of effective microorganisms and Asahi SL biostimulator) and foraging by insects [cereal leaf beetle (Oulema melanopa L.) and bird cherry-oat aphid (Rhopalosiphum padi (L.)] on the total content of phenolic compounds in winter wheat, was studied.

[Turkish (Aztec) tobbaco (Nicotiana rustica L.) unnoticeable danger?].

Tobacco harmful influence on men's health is usually linked with smoking cigarettes. Alternative ways of intake tobacco are also dangerous. Nicotine and tobacco-specific N-nitrosamines with carcinogenic activity are not only present in tobacco smoke but also of nicotine-rich product for chewing.

Flavonoids and phenolic acids of Nepeta cataria L. var. citriodora (Becker) Balb. (Lamiaceae).

Luteolin 7-O-glucuronide, luteolin 7-O-glucurono-(1-->6)-glucoside, apigenin 7-O-glucuronide as well as free aglycones luteolin and apigenin have been isolated from lemon catnip herb (Nepeta cataria L. var citriodora). Luteolin 7-O-glucurono-(1-->6)-glucoside is probably a new compound, for the first time described.

[Carotenoids as components of dietary supplements recommended for smokers and persons passively exposed to cigarette smoke].

Smoking is a very common addiction and a reason of many serious diseases of cardiovascular, respiratory and digestive systems and also a cancer. Active and passive smokers are exposed to nicotine and many carcinogenic products of tobacco smoke. Carotenoids (e.

Terpenoids and sterols from Nepeta cataria L. var. citriodora (Lamiaceae).

Isolation and GC/MS quantitative determination of ursolic acid in the herb of Nepeta cataria var. citriodora have been performed. The content of this compound was in the range 0.
