Study of Physico-Chemical Properties of Drug and Physiological Variation in Leaves of Andrographis Paniculata (Burm. F.) Nees

Meenu Sharma, R. G. Sharma and Aakanksha Sharma

Samples of Andrographis paniculata (Burm. f.) Nees of different age i.e. after 30, 60, 90, 110 and 130 days of plantation with samples of different location were studied. Results of extractive value determination show that alcohol soluble extractive value was maximum and Pet. ether soluble extractive value was least. Among all samples studied alcohol soluble extractive value of LL sample was highest (23.42%) followed by QL sample. Results of physiological variation clearly indicate that both Chlorophyll a and Chlorophyll b were more in young plants than matured ones. Results also show that as Chlorophyll content decreases Carotenoids and Anthocyanin content increases
