Abstract: Oroxylum indicum, popularly known as ‘Syonaka’, is one of the Dasamoola root species and an ingredient of many other herbal formulations. With a concern to conservation, the present study focuses on chromatographic analysis of phytocompounds present in various parts of this tree for finding possibilities to substitute aerial parts for root. In GC-MS analysis, 10, 12 and 18 bioactive compounds were identified respectively from root, stem and leaves. The abundance of the principal compound oroxylin and chrysin did not show much variation in root and stem. In LCMS analysis100 different compounds were identified from various parts. Majority of the bioactive compound like cosmosin, quercitrin, ginkolide J, rhapontin, leuteoline, hesperetin, naringenin, eriodictyol, S-4 nitrobenzyl glutathione, lecanoric acid, sennidin B, chlortetracycline, kanamycin etc. were detected in all parts. The study recommends for the use of young stem in herbal formulations instead of root, as an effective conservation strategy for this tree.
