Journal Title: Journal of Ayurvedic and Herbal Medicine - Year 2018, Vol 4, Issue 3
Abstract
Agrimonia pilosa Ledeb (AL) has received considerable attention as a herbal medicine for its applications in ethnopharmacology with heath benefits. This study aimed to investigate antioxidant activities and A549 growth inhibitory capacity from its root extract (RE) and aerial parts extract (AE). The 50% ethanol extracts were used for the tests. The total polyphenol content and the antioxidant effects comprising ABTS+ and DPPH free radical scavenging activities were evaluated. Phenolic compounds in the extracts were isolated using high performance liquid chromatography (HPLC). Lactate dehydrogenase released in medium was also evaluated. Total phenolic and flavonoid content, and in vitro antioxidant potential of the RE were higher (p<0.01) than that of the AE. Two individual phenolic compounds consisting of 4-hydroxybenzoic acid and p-coumaric acid were firstly identified in both by HPLC. The RE exhibited higher A549 inhibitory capacity compared to the AE and activated the apoptotic proteins of bcl-2, bax, bad, caspase-3 and caspase-9 in A549. In conclusion, the AL extracts were more effective in antioxidant and A549 cells inhibitory capacity.
