Abstract


The biological activities of petroleum ether (P), 95% ethanol (E) extracts and hydro-distillation (H) of Perilla frutescens (Linn.) Britton leaves were evaluated. Total phenolic contents, anti-oxidant activity (DPPH and hydroxyl radical (OH) scavenging) and the anti-inflammatory effects were determined. The volatile components of the hydro-distillation were determined by GC-MS analysis. The stability of cosmetic products containing the extract and dermal irritancy on human skin were also evaluated. The results suggested that the total phenolic content in E extract was higher than that in P extract.  All extracts presented significantly inhibited hydroxyl radical induced deoxyribose degradation with an IC50 value in the range of 0.045±0.017-0.092±0.024 mg/ml more than Trolox (IC50=1.351±0.408 mg/ml). For DPPH assay, E extract showed significantly (p<0.05) higher activity than P extract. The highest ability of inhibition exhibited in E extract was 040E (IC50=0.824±0.061 mg/ml) which is also related to GEAC (3.298±0.237 mg/g extract) and TEAC (13.002±0.933 mg/g extract) values. The anti-inflammatory effects of all E extracts at low concentration 0.0625 ug/g were higher activity to NO inhibition than those of all P extracts. GC-MS analysis showed the presence of 2-Hexanoylfuran and 1-Pentanone in all three samples. The irritation on the volunteer’s skin was not found. To conclude, P. frutescens leaves showed antioxidants activity, serving as an anti-inflammatory agent, and volatile compounds (essential oil) which might be a good plant for cosmeceutical products.
