Bligh and Dyer (B & D) or Folch procedures for the extraction and separation of lipids from microorganisms and biological tissues using chloroform/methanol/water have been used tens of thousands of times and are "gold standards" for the analysis of extracted lipids. Based on the Conductor-like Screening MOdel for realistic Solvatation (COSMO-RS), we select ethanol and ethyl acetate as being...

objective: phototoxicity is a kind of dermatitis that is activated by exposure to ultraviolet light following the administration of some drugs or natural products. artemia salina (a. salina) (brine shrimp) has been effectively applied for toxicity testing and is perfect for biological screening of many chemicals for simultaneous evaluation of toxicity and phototoxicity. the objective of this st...

This study investigated the biological activities of five benthic marine algae collected from Northeastern Region of Brazil. The tested activities included larvicidal activity against Aedes aegypti, molluscicidal activity against Biomphalaria glabrata, and toxicity against Artemia salina. Extracts of Ulva lactuca (Chlorophyta), Padina gymnospora, Sargassum vulgare (Phaeophyta), Hypnea musciform...

Efficacy of any herbal drugs depends on their chemical profile and biological activity ingredients. The anticipated efficacy drug could be achieved if authenticated ingredients that are collected as per good collection practices in the appropriate season. general problem faced industry is correct identification source plant. present study was aimed to develop chromatographic finger print profil...

Sir,?I have recently returned to a well-known firm of druggists in Rangoon a consignment of chloroform which was labelled chloloform pure B. P. (made from pure alcohol dbc." It appeared to take an excessive amount to ansesthetise : patients became very cyanotic with irregular breathing: the pulse was often weak : and many had much vomiting, and felt very ill for two days.
