Abstract
|
|
|
|
Methanol extract (1.0 wt%) of Scutellaria baicalensis George satisfied preservation standard of CTFA (The Cosmetics, Toiletry, and Fragrance Association) against Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans and Escherichia coli which were inoculated in skin lotion. Even at a low concentration (0.01 wt%) the extract showed high superoxide dismutase-like activity. The CTFA standard could also be satisfied for the above four strains when methanol extract of Liriope platyphylla were combined with the 1.0 wt% extract of S. baicalensis George. This result suggests that extract of L. platyphylla does not hinder the preservation activity of S. baicalensis George. Moreover, skin moisture content could be maintained for 6 hours after the application of a cream containing the extract of L. platyphylla.
