PRELIMINARY PHARMACOGNOSTICAL AND PHYTOCHEMICAL EVALUATION OF SHUDDHA AND ASHUDDHA HARITAKI (Terminalia chebula Retz.)
Introduction: Haritaki (Terminalia chebula Retz.) of Combretaceae family is well known drug often used in Ayurvedic therapeutics. Ayurvedic texts advised to consider the fruits that sink in stable potable water in therapeutics. As tannin is an important constituent of Haritaki, an attempt has been made to determine tannin content and other differences in acceptable and unacceptable varieties of Haritaki.
Materials and methods: Haritaki (Terminalia chebula Retz.) was collected from pharmacy, Gujarat Ayuved University GAU, Jamnagar and another sample has been collected from Indore market. These fruits were categorized into five groups, (very big, big, small, brown and Himaj) and again sub grouped into two on the basis of accepted and rejected qualities. Free hand sections and organoleptic examination was done of all samples, out of them three samples [sink big Haritaki(SBH), floating big Haritaki(FBH), very big Haritaki(VBH)] are selected for TS examination, microscopic characters, ash values, LOD, extractive values, H.P.T.L.C., Tannin content & other physico-chemical analysis.
Results and conclusion: The pH of 10% aqueous solution of SBH, FBH and VBH was 3.0, 3.2, 2.8 and tannin content 44.78%, 50.22%, 33.9% respectively. Microscopically the SBH showed abundant scleroids and rosette crystals. All the data of three samples were compared with Ayurvedic Pharmacopeia of India (API), SBH was more accepted than among three samples.
