Effects of Extraction Solvents on Concentration of Valerenic Acid and Antioxidant Property of Valeriana
نویسنده
چکیده
The effects of extracting solvents (dichloromethane, ethyl acetate and methanol) on the valerenic acid content and antioxidant activity of roots extracts of Valeriana jatamansi (cultivated and wild) were investigated. The tested plant extracts contained appreciable amounts of valerenic acid content which affects the antioxidant potential of plant extracts. Higher concentration of valerenic acid and antioxidant activity was obtained using dichloromethane, as compared to ethyl acetate and methanol. The results showed that the concentration of valerenic acid plays an important role in antioxidant activity of V. jatamansi. The concentration of valerenic acid was found in the order dichloromethane > ethyl acetate > methanol fractions in different samples of V. jatamansi. A similar trend was also found with antioxidant activity of the plant extracts.

The roots of Nardostachys jatamansi have been used as a substitute for valerian in Iranian traditions. Moreover, six species from Valeriana genus such as V. sisymbriifolia grow in Iran which has not been studied yet. We aimed to study of antioxidant effect of Valeriana officinalis, Nardostachys jatamansi and Valeriana sisymbriifolia and comparing their content of valerenic acid and valepotriate...
متن کاملEnhanced production of valerenic acids and valepotriates by in vitro cultures of Valeriana officinalis L.
Valerian (Valeriana officinalis L.) is an important medicinal plant that is widely exploited for its roots and rhizomes which contain valepotriates and valerenic acids (with putative pharmacological activities). Thus root proliferation of valerian is very important. The aim of this study was to establish a practical tissue culture method for rapid and large-scale induction of V. officinalis L. ...
