Changmora (Lasia spinosa) and Tora (Alpinia nigra) are two non-conventional medicinal plants of Assam known to be used therapeutically. The leaves of L. spinosa and shoots of A. nigra were chemically analysed for determining their phytochemical status. The results revealed the presence of alkaloids, flavonoids, phenols and terpenoids in both the plant parts. Sterols was present in L. spinosa, but found absent in A. nigra. Shoots of A. nigra contained higher quantity of total Alkaloids (215.0mg) than leaves of L. spinosa (45.50 mg). Total flavonoid and phenol contents were higher in L. spinosa (89.34 and 164.2 mg respectively) than A. nigra (54.14 and 120.7 mg respectively). The findings indicated the therapeutic potential of these plants for their use as anti-inflammatory, antioxidant, antitumor agent and various other disease preventive factors.
