Waste cooking oil has always been an environment problem in food factories and one method of effect disposing this oil without effecting the environment is to convert it to fatty acid methyl ester (FAME) using small scale pilot plant. The conversion of waste cooking oil with sodium hydroxide as a catalyst in conversional process at 22kHz speed. The reaction of time, molar ratio, speed, catalyst and amount of catalyst will be effect in FAME quality. The quality of biodiesel define is total ester content using gas chromatography. Gas chromatography analysis is a one of technique for identification and quantitation of compounds in a biodiesel sample. From biodiesel sample can identification of contaminants and fatty acid methyl ester. In this research biodiesel sample were analyses using a gas chromatography-flame ionization detector ( Perkin Elmer GC Model Clarus 500) equipped with a DB-5 HT capillary column ( 0.53mm x 5 m) J&W Scientific. The analytic conditions for ester content were as follow by: column temperature used 2100C, temperature flame ionization detector (FID) of 2500C, pressure of 80kPa, flow carrier gas of 1ml/min, temperature injector of 2500C, split flow rate of 50ml/min, time for analysis 20 minute and volume injected of 1 μl. The ester content (C), expresses as a mass fraction in present using formula (EN 14103, 2003a) calculation. Conversion of triglyceride (TG) to FAME using conversional process obtained 96.54 % w.t with methanol to oil molar ratio 6:1, 1%w.t acid sulphuric and 1% w.t sodium hydroxide catalyst.

Bergenia ciliata is a weed of hilly areas of Pakistan that generally grows in rock crevices. In the present study, flowers of this weeds were collected from Murree. The dried flowers were extracted in methanol and subjected to GC-MS analysis that showed 7 compounds in it. The predominant compound was hexanedioic acid, bis(2-ethylhexyl) ester (48.88%) followed by γ-sitosterol (22.56%). Moderately occurring compound was cyclohexane, 1,3,5-triphenyl- (12.87%). The remaining compounds namely n-hexadecanoic acid (4.97%), pentadecanoic acid, 14-methyl-, methyl ester (3.77%), 9,12-octadecadienoic acid, methyl ester, (Z,Z)-  (2.94%) and 9,12,15-octadecatrienoic acid, methyl ester, (Z,Z,Z)- (2.92%) were categorized as less abundant compounds. Literature survey indicated that these compounds possess antimicrobial, larvicidal, anti-inflammatory, anticancer and/or antidiabetic properties.

Baliospermum montanum (Wild.) Muell. Arg., (Euphorbiaceae) is a well known medicinal plant which is used in treatment of various diseases. The present study was focussed on the separation and investigation of the phytochemical compounds from ethanolic extract by GC-MS technique. The mass spectra of thecompounds found in the extract were matched with the National Institute of Standards and Technology (NIST) library. The ethanolic extract revealed the presence of 30 bioactive compounds. The major and minor phytochemical compounds are 2,15-Dithia[3](9,10)anthracenol[3](2,6)pyridinophane,1,2,3,4-tetrahydro showed the highest peak 9.32% followed by phytol-9.08%, Neophytadiene-7.38%, 8,11-Octadecadienoic acid, methyl ester (CAS)-7.06%, 4-ethyl-6-[2-(methoxycarb onyl)ethenyl]-7-[2-(methoxycarbonyl)ethyl]1,3,5,8-tetramethyl-2-vinylporphyrin-6.72%, 2-pentafluorophenylpropanal-6.43%,4,4'-Isopropylidene-bis-(2-cyclo hexyl phenol)-5.91% etc.. Further pharmacological studies are needed to find out the medicinal aspect of these compounds.
