Healthy Food Passion fruit and Skin Aging

Posted by Chantel Martiromo 

Skin aging is one of most visible ageing process which occurs constantly in our skin organ. According to the Clinical Centre of Nis, certain plant extracts may have the ability to scavenge free radicals, to protect the skin matrix through the inhibition of enzymatic degradation, or to promote collagen synthesis in the skin,  affect skin elasticity and tightness(a). Other suggested that free radicals induced domino effects in production of reactive oxygen species, can react with DNA, proteins, and fatty acids, causing oxidative damage and impairment of antioxidant system, leading  injuries damage regulation pathways of skin,  including wrinkles, roughness, appearance of fine lines, lack of elasticity, and de- or hyperpigmentation marks(b).
The degradation of the epidermal and dermal layers of the extracellular matrix (ECM), the non-cellular component present within all tissues and organs, such as UV Exposure, decline of lysosomal/endosomal cathepsin K, S and V activity(c) as well as environment factors such as irregular dryness, dark/light pigmentation, sallowness, severe atrophy, telangiectases, premalignant lesions, laxity, leathery appearance and deep wrinkling, etc.,  cause modification of the surface of skin and the physical properties of that lead to skin aging. Certain foods have been found to be effective in protect the skin against natural aging, including green tea and garlic.
Passionflower is also known as passion vines,, in the genus Passiflora , belonging to the family Passifloraceae, native to southeastern parts of the America. The herb has been used in traditional medicine in treating nervous tension including anxiety, insomnia, seizures, sleep problems and hysteria.
Passion fruit seed extract, piceatannol, and scirpusin B effected the keratinocyte by upregulated the glutathione (GSH) levels in keratinocytes in a dose-dependent manner, and suppressed the UVB-induced generation of reactive oxygen species (ROS), and enhanced matrix-metalloproteinase (MMP)-1 activity(10). A flavone chrysin from Passiflora caerulea Linn. and a benzoflavone moiety (BZF) recently isolated from Passiflora incarnata Linn in rat skin study, showed a great potential for clinical and therapeutic applications against the physiological and biochemical effects of aging(11).
