Nine samples of the heartwood of Acacia catechu extracted from trees growing in thick forest and in the open, were received from different forest divisions of Gujarat and Maharashtra, and analysed for their contents of katha and cutch. It is observed that there is no definite relation between the katha content of a tree and the density of forest in which it grows. There is, however, no marked variation in the content of cutch present in the trees growing in the thick forest or in the open.

Results of studies on methods of propagation and their optimum time of planting, etc., up to about 1-, 2- and 3-year-old plants of Rauwolfia serpentina (Linn.) Benth. ex Kurz are given. For this purpose a statistically designed experiment was conducted. The results confirm our previous indicative findings with 1-, 2- and 3-year-old plants that ischolar_main production of plants raised from seeds is much higher than that of plants raised vegetatively (ischolar_main cuttings or stem cuttings). Indeed, in the first year it is about 5 times that of plants raised from stem cuttings and about 2.4 times that of plants raised from ischolar_main cuttings (excluding mother ischolar_mains). During the second year it is about 9 times that of Stem cuttings and 2.6 times that of ischolar_main cuttings (excluding mother ischolar_mains). In the third year it is about 6.5 times that of stem cuttings and about 2.5 times that of ischolar_main cuttings (excluding mother ischolar_mains). The transplants raised from seeds sown in April have given the highest yield of ischolar_mains. There is also proportionate increase in ischolar_main production according to age. The total alkaloidal content of ischolar_mains was well above the I.P. and B.P.C. standard. Commercial plantations for ischolar_main production are best raised from seeds sown in April, under Dehra Dun conditions- A Field Method for the Extraction of Santonin from Artemsia Species

Experiments conducted in the Chakrata Hills have shown that the alkaloidal content of the leaves of Indian Belladonna (Atropa acuminala Royle ex Lindl.) is highest when the flower buds are in the primordial stage and the amount of alkaloids decreases as the development of the flower progresses. The optimum stage of growth for harvesting the leaf drug appears to be the "Advanced Flower-bud Stage".- Chemical Examination of Bark of Terminalia paniculata Roth

Analyses of Teminalia paniculata Bark shows that it is made up to 27 per cent of extractives that can be removed by slIccessive extraction with petroleum ether, ch1oroform, alcohol and water, 28 per cent of carbohydrate, 33 per cent of 'lignin' and 9.6 per cent of ash. The bark does not contain any alkaloids. It contain. 14 per cent of tannins, which have a pyrogallol nucleus in the molecule rather than a catechol nucleus along with gallic acid . β-sitosterol has been isolated and identified from the petroleum ether extract of the bark.- Studies on the Santonin Content of Artemisia brevifolia Wall.
