In the present study, we have phytochemically characterized 5 different abundant Aloe species, including Aloe vera (L.) Burm.f., using silylation followed by Gas Chromatography-Mass Spectrometry technique and compared the data using multivariate statistical analysis. The results demonstrated clear distinction of the overall phytochemical profile of A vera, highlighted by its divergent spatial arrangement in the component plot. Lowest correlation of the phytochemical profiles were found between A vera and A aristata Haw. (−0.626), whereas highest correlation resided between A aristata and A aspera Haw. (0.899). Among the individual phytochemicals, palmitic acid was identified in highest abundance cumulatively, and carboxylic acids were the most predominant phytochemical species in all the Aloe species. Compared to A vera, linear correlation analysis revealed highest and lowest correlation with A aspera (R 2 = 0.9162) and A aristata (R 2 = 0.6745), respectively. Therefore, A vera demonstrated distinct spatial allocation, reflecting its greater phytochemical variability.

Tea is the most popular beverage in the world and is the economical backbones of some countries like India, China, Kenya, Sri Lanka etc. Indian tea is very much popular among the world, specially Darjeeling tea which is famous for its flavour and taste. Among the various types of tea, orthodox tea is highly demandable for its quality. The present paper deals with various types of tea processing in India. Mainly three types of tea processing are practices in India. Among these, CTC tea processing is more common in Indian sub-continent followed by Green tea and Orthodox tea. In this paper, details manufacturing process and step wise pictorial viewed are presented. All the data are extracted from different world famous tea gardens of Darjeeling, terai and duars of Northern West Bengal.

Trichosanthes is one of the most economically important genera of the family Cucurbitaceae. Studies on trichome micro-morphology and stomata were investigated for six species of Trichosanthes. All species has been recorded from the Terai and Duars of West Bengal. Range of variability in Trichosanthes species are quite variable, trichomes types including uni-multiseriate, macro-microform, conical, candelabra, capitated, glandular and non- glandular. Stomatal character shows variability (Paracytic, Actinocytic, Anomocytic and Diacytic). Trichomes and stomatal characters are utilised for phenetic studies which found to be important taxonomic tools to solve any disputes at least at or below species level.
