Delforge is a Mediterranean species, known as the giant orchid, having scented flowers arranged in a dense inflorescence. Flowers accumulate anthocyanins and are used to obtain a polyphenol-rich hydroalcoholic extract. The extract has been shown to contain flavonoids, scopoletin, and phenolic acids, exert powerful antioxidant activity, strongly inhibit matrix degrading enzymes, and promote keratinocyte re-epithelialization after wounding. Hence, the complexity of the data indicates that the extract has distinct skin-preserving properties. The in vitro propagation of the orchid has been developed, making it exploitable as a source of bioactive substances for skin care applications. View this paper
