Table S1. DPPH radical scavenging activity of plants extracts and quercetin. The supplementary file compares the DPPH radical scavenging activity of different methanolic plant extracts in terms of its percentage of inhibition and IC50 values. Quercetin was used as a standard to compare the efficacy of the plant extracts. Table S2. DPPH radical scavenging activity of poly herbal formulations. The supplementary file compares the DPPH radical scavenging activity of poly herbal formulations in terms of its percentage of inhibition and IC50 values. TableS3. Total reducing power of methanolic plant extracts. The supplementary file compares the ability of plant extracts to reduce ferric iron to ferrous iron, using vitamin C as a standard to calculate the reducing power of the extracts equivalent to vitamin C. Table S4. reducing power of poly herbal formulations. The supplementary file compares the ability of poly herbal formulations to reduce ferric iron to ferrous iron, using vitamin C as a standard to calculate the reducing power of the extracts equivalent to vitamin C. Table S5. Elastase inhibition capacity. The supplementary file compares the elastase inhibition capacity of plant extracts and PHF1 with copper sulfate as standard. Table S6. Nitric oxide scavenging capacity. The supplementary file compares the nitric oxide scavenging capacity of plant extracts and poly herbal formulations with curcumin as standard. Table S7. In vitro inhibitory capacity of poly herbal formulations. The supplementary file enlists the percentage of cells inhibited by poly herbal formulations at different concentrations against NIH3T3 fibroblast cells and A375 malignant melanoma cells (PDF 727 kb
