Abstract Plant derived products are widely used in cancer treatment. Gall species has been preferred for treatment various diseases in folk medicine, but there are few studies on the anticancer effects of gall species. The present study reports the antioxidant activity and total secondary metabolites of extracts of A. tomentosus galls. The antioxidant potency of galls was carried out using different in-vitro model systems. Their cytotoxic efficacy on Mia-Paca cell line was also explored. Gall extract was found to contain a large amount of phenolic acids. The extract potently scavenged free radicals including DPPH ( IC50 9.56 ± 1.08 µg/mL), ABTS (IC50 18.51 ± 0.25 µg/mL). It can be seen as a potential source of antioxidants according to β-carotene/linoleic acid method (%92.58 ± 0.92) and Phosphomolybdenum assays (104.36 ± 4.95 mgAE/g). Gall extract also posses ability of metal chelating (%40.07 ± 2.30) and F e3+ (184.01 ± 2.83 mgTE/g) and C u2+ (89.81 ± 0.96 mgTE/g) reducing activity. According to total secondary metabolites tests, gall extract showed high total phenolic, total flavonoid and total tannin amount. HPLC analysis of the extract suggested it to contain caffeic acid (424.068.479 µg/g), ellagic acid (187.696.132 µg/g). XTT assay revealed gall extract to enhance percent survival of Mia-Paca2 cell line exposed A. tomentosus extracts. The best cytotoxic effect was determined in acetone extracts ( IC50: 124.7 µM). Expression of some genes (Bax, Bcl-2, FAS, BID, caspase-3, caspase-8, caspase-9, caspase-10, FADD, TRADD) in the apoptosis pathway was determined to invastigate apoptosis inducing activity. These results indicate that A. tomentosus galls possess potent antioxidant activity, when tested both in chemical as well as biological models.

Introduction In recent years, the use of herbs for the prevention and treatment of cancer has gained more attention, due to various phytochemical components and fewer side effects. Cytotoxic potentials of four different medicinal plants against six different cancer cell lines (A-549, CCC-222, DU-145, MCF-7, K-562 and PC-3) and one normal cell line (Beas-2B) were investigated [1]. In another study was revealed that three
