To evaluate therapeutic efficacy of Achyranthes aspera against arsenic toxicity, mice were given aqueous ischolar_main and leaf extracts at both low and high doses (100 and 200 mg/kg body wt) after being intoxicated with sodium arsenate (0.1 mg/kg body wt). Significant alterations (P < 0.05, 0.001) were seen in various haematological parameters, Ig level, macrophage yield, viability, phagocytic index and progesterone level. Results clearly depict that both A. aspera extracts significantly restore the unbalanced level up to the normal. This study shows the protective efficacy of A. aspera on altered haematological and immunological system. It is possible that future work on drug formulation may use this plant as a source.Keywords

White grubs belonging to subfamilies Melolonthinae and Rutelinae of Scarabaeidae (Coleoptera) are ubiquitous pests. Studies during 2013 and 2014 document the species diversity of white grubs in the sub- Himalayan and northern plains of India. Surveys conducted in four states, viz. Himachal Pradesh, Uttarakhand, Uttar Pradesh and Rajasthan revealed high species diversity representing 65 species under 16 genera. The species richness, evenness and composition varied among the states. Higher species diversity was recorded in Uttarakhand and Himachal Pradesh of the sub-Himalayan region when compared to Uttar Pradesh and Rajasthan of the northern plains. The species abundance distribution followed log normal distribution in all places except Uttarakhand, where the curve skewed to the left due to overweight of species with low abundance. The species dominance and abundance patterns in different regions are presented. The new distributional records, Anomala pictipes Arrow and Popillia macclellandi Hope from Uttarakhand, Anomala propinqua Arrow and Popillia marginicollis Hope from Himachal Pradesh and Anomala stenodera Arrow from Uttar Pradesh are provided.Keywords

Indigofera tinctoria is a well-known medicinal plant that possesses several therapeutic activities. Isothiocyanate derivative from hydroethanolic extract of Indigoferatinctoria (HEIT) was isolated by means of chromatographic techniques, i.e. adsorption chromatography,thin layer chromatography and high-pressure liquid chromatography. Structural characterization of isolated compound was done using various spectroscopic techniques (liquid chromatograph–mass spectrometry,1H nuclear magnetic resonance and Fourier transform-infrared spectroscopy) and the possible structure was identified as 1-[1,2-Diisothiocyanato-2-(3-isothiocyanato-2,2-dimethyl-propylsulphanyl)-ethoxy]-3-isothiocyanato-2,2-dimethyl-propane (C16H22N4OS5;m/z 446.70; ITC-1). Maximum yield of ITC-1 was obtained as 22 mg/5 g HEIT with 97% purity.Keywords
