TL;DR: Wound healing properties of plant extracts that contain the naphthoquinone natural products alkannin and shikonin have been known for many centuries and their production both by cell cultures and chemical synthesis has been studied extensively.

TL;DR: In this paper, seven different extracts, fractions and residues of Navel sweet orange (Citrus sinensis) peel were evaluated for their radical scavenging activity by the DPPH and luminol induced chemiluminescence methods.

TL;DR: The DPPH radical scavenging activity of a natural product that possesses biological properties, an extract of Crocus sativus L. (saffron), grown in Crocos, Kozani (Greece), and some of its bioactive constituents (crocin, safranal) was studied.

TL;DR: The findings and advances on the molecular and biological properties of A/S that promote wound healing are reviewed, revealing a new class of drugs that hold promise as the basis for many valuable therapeutic targets.

TL;DR: The results suggest that the ethyl acetate fraction of navel Citrus sinensis peel consists of significant antioxidant compounds and can be used as a food additive of natural origin or a pharmaceutical supplement using as a source of peel the byproducts of the orange juice industry.
