A neutral polysaccharide (yield 0.5%) has been extracted and isolated from the leaves of Bryophyllum pinnatum with 1% Acetic acid consisting of D-Gatactose and L-arabinose in the Molar ratio of 2:4:1, Systematic chemical and spectral analysis for structural elucidation of the mucilage showed that it may be designated as "Arabinogalactan'.

The chemical pesticides used in the world in recent years have resulted in severe implications in the development of pesticidal resistance in key pest species, residues in food chain and losses in purity of eco-system as well as human health. Among non-chemical options bio-pesticides which are target specific, eco-friendly and bio-degradable are potential alternatives to chemical pesticides. FYM 10 t/ha+Azotobecter @ 1.25 kg/ha was most effective treatment against sucking pests of brinjal and recorded minimum population of jassid (8.63 jassids/3 leaves), black aphid (7.16 aphids/3 leaves), white fly (3.85 nymphs/3 leaves) and fruit infestation (17.07%). The high per cent reduction of fruit and hadda beetle infestation was recorded from FYM 10 t/ha+neem seed kernel @ 500 kg/ha. Highest marketable fruit yield increased (92.00 q/ha) from FYM 10 t/ha+neem seed kernel @ 500 kg/ha over untreated check. The maximum net return (Rs. 13095.0) was obtained from FYM 10 t/ha+neem seed kernel @ 500 kg/ha treated plots. The maximum incremental cost : benefit ratio was obtained from FYM 10 t/ha+Azotobecter @ 1.25 kg/ha (1 : 11.42).

The micellar catalysed reaction with hydroxide ion and mono phosphate ester 0f 4-chloro-3-methyl phenyl (4-CMPP) has been examined in buffered solution medium (at pH 8.0-10.0) with borate ions. First order rate constant for the reaction of OH- ion with 4-CMPP through maxima inhibited the concentration of sodium lauryl sulphate (Nals), micelles of Nals are least reactive. Anionic micelles of [Nals] have little effect on the reaction rates probably because anionic micelles strongly inhibit the nucleophilic effect.

Monocrotophos (MCP) is a widely used organophosphorus pesticide which controls a wide spectrum of chewing, sucking and boring insects. The aim of this study was to evaluate neurotoxicity and genotoxicity of Monocrotophos on rats. The acetylcholinesterase activity was measured in both brain and liver as a biomarker of toxicity. The results show that it is highly toxic cholinesterase inhibiting pesticides. Comet assay study was used to assess the possibility of monocrotophos induction of DNA damage where the increase in comet tail length relates to the extent of DNA single strand breaks. The results also indicated that exposure to Monocrotophos is associated with increased DNA damage.
