文摘
The effect of passion fruit, the fruit of Passiflora edulis, on melanin inhibition and collagen synthesis was studied using cultured human melanoma and fibroblast cells. Passion fruit was divided into three parts, rind (PF-R), pulp (PF-P), and seed (PF-S), and each part was extracted using 80% ethanol. The concentration of polyphenols was higher in PF-S than in PF-R or PF-P. Treatment of melanoma cells with PF-S led to inhibition of melanogenesis. In addition, the production of total soluble collagen was elevated in dermal fibroblast cells cultured in the presence of PF-S. PF-R and PF-P did not yield these effects. Furthermore, the removal of polyphenols from PF-S led to the abolishment of the effects described above. We discovered that piceatannol (3,4,3′,5′-tetrahydroxy-trans-stilbene) is present in passion fruit seeds in large amounts and that this compound is the major component responsible for the PF-S effects observed on melanogenesis and collagen synthesis.
