Physicochemical properties, antimicrobial and antioxidant activity of ganoderma transparent soap

Abstract

Ganoderma lucidum has been known as a cosmetic source. It contains bioactive ingredients such as triterpenoids and polysaccharides. The present study was to formulate transparent soap enriched with Ganoderma (Ganoderma lucidum) extract and investigate its antibacterial and antioxidant activity. Formulation of Ganoderma transparent soaps was made by hot process method. The results showed that Ganoderma transparent soaps have moisture content 21.8%, pH 9.22, total fatty matter 41.66%, free fatty acid 1.08% and chloride acid 5.57%. Antibacterial assay by agar well diffusion method showed that Ganoderma transparent soaps were more active against the S. aureus than the Gram-negative bacteria and even C. albicans. The antioxidant activity assay using 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical showed that the IC50 of transparent soap was 1.53 mg/mL.
