| Summary: | The present investigation assessed the anticancer potential and chemical profile of the polyherbal formulation (PHF6) against human breast cancer cells. The plants (Alchemilla vulgaris, Cichorium pumilum, Crataegus azarolus, Eruca sativa, Ferula hermonis, and Hypericum triquetrifolium) were combined in equal quantities and extracted using soxhlet apparatus. The total polyphenolic (TPC) of the hexane and chloroform extract of PHF6 were 3.11 ± 0.004 and 7.88 ± 0.004 µg/mL (as gallic acid equivalent), respectively. The radical scavenging activity (RSA) values for the hexane and chloroform extract were 35.1 % ±0.01 and 36.9 % ±0.06, respectively. For hexane extract, the IC50 values were found to be 82.8 and 48.7 µg/mL against MCF-7ER(+)/PR(+) and MDA MB-231ER(−)/PR(−), respectively. Similarly, the IC50 value of chloroform extract was 44.4 µg/mL against both cell lines. The MDA MB-231ER(−)/PR(−) cells stained with DAPI post-treatment with hexane and chloroform extract showed cell shrinkage, nuclear fragmentation, and chromatin condensation. Moreover, GC–MS screening of the PHF6 revealed several compounds with different reported biological activities, such as phytol and octadecanoic acid. PHF6 showed promising anticancer activity against cancer cells tested, thus deserving more clinical studies in the future.
