the fruit of melia azedarach l. (meliaceae) was extracted with hexane, and its fatty acids methyl ester was analyzed using gc/ms. thirteen components representing 85.1% of the total extract were identified. the major components identified were methyl palmitate (18.8%), methyl linolenate (16.1%) and methyl linoleate (9.8%). the fruits’ extract had a lc50 of 5.5 ppm against the larvae of anophles...

BACKGROUND In this study, we investigated whether lobetyolin, lobetyol, and methyl linoleate derived from Codonopsis pilosula affect MUC5AC mucin secretion, production, and gene expression from airway epithelial cells. METHODS Confluent NCI-H292 cells were pretreated with lobetyolin, lobetyol, or methyl linoleate for 30 minutes and then stimulated with phorbol 12-myristate 13-acetate (PMA) fo...

Antioxidant enzymes are scavenger reactive-oxygen intermediates and are involved in many cellular defense systems. We previously reported that a crude extract of Garnoderma lucidum, a medicinally potent mushroom, profoundly increased the catalase gene expression and enzyme activities in mouse livers (Park et al., J. Biochem. Mol. Biol. 34. 144-149, 2001). In this study, we elucidated the detail...

Ten fatty acid alkyl esters isolated from Oxalis triangularis, were evaluated for the effects on melanogenesis using mouse B16 melanoma cells. Treatment of methyl linoleate, methyl linolenate, ethyl linoleate and ethyl linolenate significantly blocked forskolin-induced melanogenesis and inhibited tyrosinase activity. In addition, we found that they inhibited cAMP production, suggesting that the...

IN a previous communication [Hume et al. 1938] experiments were described in which the relative potencies of methyl linoleate and Jinolenate in curing the fat-deficiency disease of rats were determined. The finding of Burr et al. [1932] was confirmed that the presence of either of these acids in a fat-free diet is able to promote the weight increase of rats but, in contrast with the results of ...
