In the current study, biodiesel properties of fatty acid methyl ester (FAME) derived from fats four gamma-irradiated mutants (Cl801, Cl802 Cl803 & Cl804) and wild type (ClWT) Chlorella sp. KM504965 were determined compared with American Society for Testing Materials (ASTM), European Norm (EN) Indian standards (IS). Maximum concentration saturated acids (62.69%), monounsaturated (36.29%) pol...

ABSTRACT Eight different 3-year cropping systems, consisting of soybean-canola, soybean-barley, sweet corn-canola, sweet corn-soybean, green bean-sweet corn, canola-sweet corn, barley-clover, and continuous potato (non-rotation control) followed by potato as the third crop in all systems, were established in replicated field plots with two rotation entry points in Presque Isle, ME, in 1998. Cro...

Procedures for preparing 4,4-dimethyloxazoline (DMOX) and pyrrolidine derivatives from fatty acid methyl esters (FAMEs) were modified to provide milder simpler conditions the derivatization reactions widely used in mass spectrometric analysis of acids. DMOX obtained overnight at room temperature presence sodium borohydride. The proposed method, involving a low-temperature condensation-cyclizati...

      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 agai...

Background and Aims: Alysicarpus glumaceus is a plant used in Africa, Asia some parts of the Arabian Peninsula with folkloric claims having anti-tussive, anti-asthmatic, anti-diarrheal, abortifacient, anti-psychotic, anti-inflammatory, diuretic stimulatory activities. The aim this study was to determine phytoconstituents present methanol extract (ME) its fractions. Methods: Standard qualitative...

A new micro-procedure for the quick regiospecific analysis of triacylglycerols (TAG) with a 1,3-specific lipase, Lipozyme IM 20 (produced from strains of Muccor miehei) is described. After dissolution of triacylglycerols in butan-1-ol or butan-2-ol 250 mg of Lipozyme IM 20 were added and the whole mixture was agitated. This operation was repeated 5-10 times and the esterified fatty acids in the...

We investigated the effect of dietary conjugated linoleic acid (CLA) along with n-3 polyunsaturated fatty acid (n-3 PUFA) on yolk fatty acid composition and volatile compounds in eggs that were raw (RA), hard-boiled (HB), or hard-boiled, irradiated (HBI, 2.5 kGy). Single Comb White Leghorn laying hens (n = 40) were randomly assigned to one of the four experimental diets containing 0, 0.5, 1.0, ...

A polar fatty acid has been observed as a component of an ornithine-containing lipid of Thiobacillus thiooxidans. A comparison of thin layer chromatographic mobilities of reference compounds to those of the natural acid and its derivatives suggested that the acid was a 2-hydroxy fatty acid. The presence of a cyclopropane function in the acid was indicated by W-labeling experiments and infrared ...

BACKGROUND Leucas cephalotes has been used by many tribes to treat variety of diseases and known to have many essential secondary metabolites. To the best of our knowledge, it is the first comparative analysis of total fatty acid (FA) composition and α-amylase inhibition activity of L. cephalotes. OBJECTIVE The present study is carried out to explore the antihyperglycemic activity and FA cont...
