The lipid fraction constituents as well as evaluation of anti-anaphylactic activity of
PRUNUS MAHALEB L.
Kernels were studied.
Prunus mahaleb L. kernels were obtained from the local market in Cairo, Egypt. Investigation of the fatty acids revealed that oleic and linoleic acids are the major constituents. 12 compounds were identified from the hydrocarbon fraction. The sterol fraction comprises of cholesterol, stigmasterol, β-sitosterol and campesterol. The pharmacotoxicity studies were carried out on total and defatted ethanolic extracts as well as the oil fraction. The oil fraction proved to be extremely safe and free from any acute lethal toxicity in intraperitoneal (i.p.) and oral doses up to 100 ml/kg.
In vivo assessment of prophylactic efficacy was afforded by 7 days course of daily medication schedule of sensitized adult male guinea pigs against ovalbumin bronchospasm. The prophylactic anti-inflammatory activity of the total ethanolic extract was higher than that of the defatted ethanolic extract. In addition, the lipid fraction of
Prunus mahaleb L. kernels evoked complete anti-inflammatory efficacy among the survival animals receiving low and medium doses.
