Well managed groves of bay rum tree are harvested once a year or 3 times in 4 years. Correspondence to Bull. Thirty six adult Female Wister albino rats (150175g) were divided into six groups each of six. To date, there are no literature reports about the phenolic compounds and pharmacological activities of P. racemosa (Mill) J. W. Moore leaves. Few studies were conducted concerning the previously isolated compounds from Pimenta species. Therefore, compound 8 was identified as 1-O-galloyl-4, 6-(S)-hexahydroxydiphenoyl--D-glucopyranose (Strictinin). The presence of pentopyranose and pentofuranose equilibrium was evidenced also from the C-4 pentose resonance as four signals at ppm 80.06, 79.3, 72.09 and 69.10 indicative for the four stereoisomers mixture. 1H-NMR data revealed the presence of two singlets signals one of which for two proton at 6.69ppm and the other for one proton at 6.50ppm characteristic for a C-glycosidic flavogallonoyl group attached to C-1, C-2, C-3 and C-5 and HHDP at C-4 and C-6 of an open chain glucose.

Gastric lesions were induced in rats by oral administration of 1mL 70% ethanol single dose [19]. grisea is so common and has such a negative effect on the quality of the oil that it is called "false bay rum tree". Bay leaves were used for flavouring by the ancient Greeks. [13] While these plants are not sold anywhere for culinary use, their visual similarity to bay leaves has led to the oft-repeated belief that bay leaves should be removed from food after cooking because they are poisonous. g Higher magnifications of (f), showed sever destruction of the mucosal glands (thin arrow) (H&E X 200). Kits for alanine aminotransferase (ALT), aspartate aminotransferase (AST) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) obtained from Sigma Chemical Company, USA were used for biological evaluation.

Bay leaves can also be used scattered in a pantry to repel meal moths,[7] flies,[8] and cockroaches. The oil is used on a limited scale for flavouring foods, chiefly sauces. The four stereoisomers mixture for 10 was established from the presence of carbon resonance at ppm 101.15, 101.07 and 99.42, 99.34 which attributed to the hemiketal carbon resonance of the pentose moiety with carbon resonance at 47.03, 46.96 and 45.86 for C-1 due to isomerism of the pentose moiety between pyranose and furanose as well as anomeric equilibria in both conformers of sugars.
