| Abstract |
Purpose
of this study is to evaluate the usefulness of fermented bamboo shoot sheath (BSS) for functional cosmetics. BSS was fermented using the mixed culture of Lactobacillus plantarum and Weissella cibaria. Antioxidant compounds, antioxidative activity, beauty-related enzymes (tyrosinase, collagenase, and elastase) inhibition, antibacterial activity, and keratinocyte growth activation effect of unfermented and fermented BSS extract were analyzed in the same way. The content of anthocyanin, polyphenol, total phenolic compounds, and total flavonoid in unfermented BSS extract were 1.08 mg/g, 43.67 mg/g, 17.14mg/g, 1.13mg/g, respectively and those in fermented BSS extract were increased to be 1.33mg/g, 52.95mg/g, 23.89mg/g, 1.62mg/g, respectively. ABTS radical-, DPPH radical-, and nitrite radical-scavenging activities of unfermented BSS extract were 55%, 62%, and 49%, respectively, and those of fermented BSS extract were 64%, 73%, and 53%, respectively. The tyrosinase- and collagenase-inhibitory activities of both unfermented and fermented BSS extract were approximately 80% and 25%, respectively. Meanwhile, the elastase-inhibitory activity of unfermented BSS extract was not detected but that of fermented BSS extract was shown to be 10%. The antibacterial activity of unfermented BSS extract was not detected but fermented BSS extract inhibited growth of Gram(+) Staphylococcus epidermis and Gram(-) Escherichia coli. Growth of keratinocyte cell line (HaCaT) was promoted by unfermented and fermented BSS at the level of 10 and 25%, respectively. Thus, the water extract of BSS was useful as the ingredient for functional cosmetics and the usefulness of specific factors was improved by the fermentation. |
