The extract of Bletila flower was obtained by extraction of its components,and its cytotoxicity,whitening,antioxidant,and anti-ag-ing effects were studied.The results showed that the extract of Bletila flower had no cytotoxicity to B16 cells and fibroblasts,indicating its safe use.At a concentration of 0.5 mg/mL,the extract could inhibit the activity of tyrosinase in B16 cells but did not inhibit melanin synthesis,in-dicating its whitening effect under certain conditions.The extract of Bletila flower exhibited significant antioxidant properties,with free radical scavenging and iron ion reduction capabilities comparable to vitamin C.Additionally,it promoted the production of hyaluronic acid in fibro-blasts.In the skin,hyaluronic acid forms extracellular matrix with elastin and collagen,providing elasticity and resilience to the skin.These data suggest that the extract of Bletila flower has the potential to whiten,antioxidant,and promote hyaluronic acid production in fibroblasts.
