PHYSICOCHEMICAL ANALYSIS OF MARKET SAMPLE OF ARJUNA (TERMINALIA ARJUNA)Abstract
Arjuna is a well-known drug in Ayurveda. It is mainly used for heart disease, Obesity, and hemorrhagic disorders. It is used in various dosage form in Ayurveda such as powder, milk-based decoction, alcoholic fermented liquids, tablets, etc. Its bark is used for therapeutic purposes. Although it is widely available all over India, most of the time it is procured from the market; hence it needs to assure the quality of marketed Arjuna for standard quality formulations. Ayurvedic pharmacopeia of India (API) has given a monograph of Arjuna bark. So in this study, authentication, organoleptic, macroscopic, microscopic, and physicochemical analysis of a market sample of Arjuna was carried out. Organoleptic, macroscopic, microscopic studies have shown relatively similar characteristics as per standard. In physicochemical analysis, foreign (0.06%) matter was within normal range. Ash value (27.77%) was higher whereas acid insoluble ash (1.08%) almost matches with standard value, which shows more inorganic contents in Arjuna. Acid insoluble ash was nearly the same as a standard value. Water soluble extractive value (19.98 %) was good in studied sample which ensures its water based formulations. However alcohol soluble extractive value (17.91%) was less than standard. pH (4.85%) value is the new parameter added in this study which may be considered as reference for further study. This study added this parameter (pH) for further comparative analysis. Further qualitative, as well as HPTLC study for main marker identification and quantification, needs to carry out with more market samples from various regions in order to ensure market sample quality.
