Abstract
Opuntia ficus-indica (L.) Miller (OFI), belonging to the family Cactaceae, is widely cultivated not only for its delicious fruits but also for its health-promoting effects, which enhance the role of OFI as a potential functional food. In this study, the in vitro collagenase and elastase enzyme inhibitory effects of extracts from different parts of OFI were evaluated. The most promising extracts were formulated as creams at two concentrations (3 and 5%) to investigate their effects on a D-galactose (D-gal)-induced skin-aging mouse model. The ethanolic extracts of the peel and cladodes exhibited the highest enzyme inhibitory effects. Cream made from the extract of OFI peel (OP) (5%) and cream from OFI cladodes extract (OC) (5%) significantly decreased the macroscopic aging of skin scores. Only a higher concentration (5%) of OC showed the normalization of superoxide dismutase (SOD) and malondialdehyde (MDA) skin levels and achieved significant improvements as compared to the vitamin E group. Both OC and OP (5%) showed complete restoration of the normal skin structure and nearly normal collagen fibres upon histopathological examination. The Ultra-Performance Liquid Chromatography High Resolution Mass Spectrometry (UHPLC-ESI-TOF-MS) metabolite profiles revealed the presence of organic acids, phenolic acids, flavonoids, betalains, and fatty acids. Flavonoids were the predominant phytochemical class (23 and 22 compounds), followed by phenolic acids (14 and 17 compounds) in the ethanolic extracts from the peel and cladodes, respectively. The anti-skin-aging effects could be attributed to the synergism of different phytochemicals in both extracts. From these findings, the OFI peel and cladodes as agro-waste products are good candidates for anti-skin-aging phytocosmetics.This publication has 105 references indexed in Scilit:
