Polyphenolic contents and antioxidant activities of aerial parts of Salvia multicaulis from the Iran flora.

Folk medicine sometimes involves the use of salvia species for therapeutic purposes. Polyphenols with the highest amounts included rosmarinic acid (7.358mg/g), catechin (1.5 mg/g), vanillin (1.00 mg/g), chlorogenic acid (0.53 mg/g), quercetin (0.16 mg/g), and p-coumaric acid (0.015). Furthermore, the results showed that S. multicaulis has a high content of total phenol (4.39 mg/g) and DPPH activity (8.44 mg/g). Salvia multicaulis could be potentially used as a medicinal plant because of its antioxidant activity and polyphenol content. [ABSTRACT FROM AUTHOR]
