METHODS AND RESULTS: Pueraria tuberosa Linn (PT), Leguminosae (Fabaceae), known as Bidaarikand [6] is an extensive perennial climber, with palmately arranged leaves, blue colored flowers and half inches thick bark [7], growing throughout tropical parts of India, mostly in moist regions, monsoon forests and coastal tracts.
Its tuberous root, which is brown in color and slightly curved, is in clinical use for rejuvenation therapy. Its microscopic picture reveals the presence of prismatic calcium crystals and tanniniferous cells. It's major chemical constituents include flavones [C-glycoside (5,7,3',5'-tetrahydroxy-4'-methoxyflavone-3'-O-α-Lrhamnopyranosyl1→3-O-β-D-galactopyranoside)], Isoflavones (Puerarone), Coumstan (Tuberostan, Puerarostan) [8], Epoxychalcanol [Puetuberosanol], (3'-hydroxy-4'-phenoxy-α,β-epoxychalcan-α'ol)] [9], Pterocarpanoids [Hydroxytuberosin, Anhydroxytuberosin (3-O-methylAnhydrotuberosin)] [10], and Tuberosin [11].
CONCLUSIONS:
The powder of PT root-tubers are in clinical use as anti-aging and also as tonic, aphrodisiac, demulcent, lactagogue, purgative, cholagogue and also in scorpion sting. Besides, it is also useful in emaciation of children, debility and poor digestion [6,7]. Other investigators have reported it for skin care, as anti-fertility [12]. One of its phytochemical, purerin, has been associated with anti-diabetic property [13]. |
