SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Leaf, stem and root of Murraya paniculata (L.) Jack was extracted in four different organic solvents (petroleum ether, ethyl acetate, acetone and methanol). The extracts were tested on the mortality of adult male and female of Callosobruchus maculatus F. All the evaluated extract was toxic to both the sexes. Males generally showed higher susceptibility compared to females. Petroleum ether extract was more toxic than others. It was in the order: pet. ether > EtOAc > acetone > MeOH extract. Leaf extract was most toxic in comparison to stem and root extracts. It was in order: Leaf > root > stem. Generally, 72 hours exposure exhibited lower LD50 values compared to 24 and 48 hours.
