Abstract:
BACKGROUND: Scutellaria baicalensis Georgi extract is used as a traditional herbal medicine. The efficacy of Scutellaria baicalensis Georgi extract is known for antioxidative activity, antiinflammation effect, antibacterial effect, inhibitory effect of melanin synthesis, sun protection effect, antiallergy effect, and etc. OBJECTIVE: We confirmed the cell viability or inhibitory effect of melanin synthesis in HaCaT (human keratinocyte cell line) and B16F10 (murine melanoma cell line) cells and the skin safety test through a clinical test (dermal irritation study) for Scutellaria baicalensis Georgi extract, according to the extraction methods. METHODS: We checked the cell viability, using MTT assay and inhibitory effect of melanin synthesis in B16F10 cells or HaCaT cells for thirty one Scutellaria baicalensis Georgi extract, according to the extraction methods. Then, we evaluated the skin safety for selected eight Scutellaria baicalensis Georgi extract through a primary dermal irritation test. RESULTS: Among the thirty one Scutellaria baicalensis Georgi extracts, according to the extraction methods, we selected eight Scutellaria baicalensis Georgi extracts that were not detected with cell toxicity in HaCaT cells and B16F10 cells, and could have inhibited the melanin synthesis in B16F10 cells. The selected eight Scutellaria baicalensis Georgi extracts identified the skin safety through a primary dermal irritation test. CONCLUSION: We expect clinical trials for whitening efficacy based on inhibitory effect of melanin synthesis and human skin safety for Scutellaria baicalensis Georgi extracts.
