2015
Singh, Bharat | Sharma, Ram Avtar
The antioxidant activity of the callus of Phyllanthus emblica was tested by using DPPH− radical scavenging, reducing power, superoxide anion, and metal chelating scavenging models. Digallic acid was the major compound in quantity both in vivo (2.61 ± 0.887%) and in vitro (2.89 ± 0.997%) in 6-week-old cell cultures. Digallic acid demonstrated maximum antioxidant activity against the antioxidant systems, while other compounds exhibited mild-to-moderate antioxidant activity. Among the isolated phytochemicals, putranjivain-A showed maximum activity against Escherichia coli (85 μg.mL ⁻¹) and Rhizoctonia phaseoli (70 μg.mL ⁻¹).
