Abstract: 本研究著重在中草藥植物萃取液之防曬成份之探討與應用以應用在化粧品配方之評估,本研究選擇20種於文獻記載指出具防曬美白及抗氧化作用之中草藥,進行紫外光吸收測試,並從中篩選出松樹皮、黃芩、薑黃水萃液均具有吸收紫外光區光線之能力,然而其中又以松樹皮水萃取物吸收光譜能力表現最佳。
加入不同濃度之松樹皮萃取液進行細胞存活率(MTT)及細胞毒性試驗(LDH),發現人類表皮細胞(HS-68) 在濃度3%之松樹皮萃取液中細胞存活率最高且細胞毒性低,將此一濃度之樣品加入乳液中進行防曬係數測試,其防曬係數可達SPF8.81。
This research investigates herb extracts as a potential sun screen ingredient in cosmetics. As cited in this experiment twenty herbs were tested for their sun protection and whitening factor as well as their anti-oxidizing properties.
Pine bark, scutellaria, and turmeric extract showed viable results in ultraviolet ray absorption, in particular pine bark extract showed the most significant viability in spectrum absorption spectroscopy (spectrophotometer or spectrometer).
By testing of MTT assay kit (MTT) and Cytotoxic Assay (LDH) in different concentrations of the pine bark extract, it was found that the cells in the epidermis (HS-68) had the highest survival rate and lowest toxicity levels in 3% concentration pine bark extract. Adding the same concentration of the extract into emulsion to test out its sun protection factor consequently yielded a SPF 8.81.
The experimentation resulted in a practical application of the extract in the cosmetic formula. Assessment of in vitro tests revealed a differentiation in outcome, the results do show the pine bark extract can be used as cosmetic sunscreen.
