Abstract:

Yellow Himalayan raspberry, a wild edible fruit, was analyzed for phenolic contents, and antioxidant, antibacterial and antiproliferative activities. Phenolics were extracted using 80 % aqueous solvents containing methanol, acidic methanol, acetone and acidic acetone. Our analysis revealed that the acidic acetone extracts recovered the highest level of total phenolics (899 mg GAE/100 g FW) and flavonoids (433.5 mg CE/100 g FW). Free radical scavenging activities (DPPH, ABTS, superoxide and linoleate hydroperoxide radicals) and ferric reducing activity were highest in the acetone and acidic acetone extracts. No metal chelating or antibacterial activity was detected in any of the extracts. Acetone and methanol extracts showed potent antiproliferative activity against human cervical cancer cells (C33A) with an EC50 of inhibition at 5.04 and 4. 9 mg/ml fruit concentration respectively, while showing no cytotoxicity to normal PBMCs cells. Therefore, the present study concluded that the yellow Himalayan raspberry is a potent source of phytochemicals having super antioxidant and potent antiproliferative activities.
