From waste to health: sustainable exploitation of grape pomace seed extract to manufacture antioxidant, regenerative and prebiotic nanovesicles withi…
2020
AbstractPomace seed extract loaded vesicles were prepared as promising technological and green solution to exploit agri-food wastes and by-products, and develop high value-added products for human health. An antioxidant extract rich in bioactive compounds (epicatechins, catechin, gallic acid, quercetin and procynidins) was obtained from the seeds isolated from the pomace of Cannonau red grape cultivar. The extract was incorporated into phospholipid vesicles ad hoc formulated for intestinal delivery, by combining them, for the first time, whit a maltodextrin (Glucidex). Glucidex-transfersomes, glucidex-hyalurosomes and glucidex-hyalutransferomes were prepared, characterized and tested. Gluci…
Phytocomplexes extracted from grape seeds and stalks delivered in phospholipid vesicles tailored for the treatment of skin damages
2019
Abstract In the present work, red grape seed and stalk extracts were incorporated in vesicular systems designed for topical application. The phytocomplexes were obtained by maceration of biomasses in ethanol and subsequent lyophilisation. Seed extract was rich in catechin, epicatechin, epicatechin gallate, while gallic acid, epigallocatechin gallate, quercetin, quercetin 3-glucoside and malvidin-3-glucoside were detected in higher amounts in the stalk extract. Both extracts were incorporated in liposomes, hyalurosomes and transfersomes. In addition, hyalo-transfersomes were developed for the first time in this work, by combining the main modifiers of hyalurosomes and transfersomes (i.e., so…
