Crustacean cardioactive peptide (CCAP) is a highly conserved, amidated cyclic nonapeptide with the primary structure PFCNAFTGC-NH2 (ProPheCysAsnAlaPheTyrGlyCys-NH2) and a disulfide bridge between Cys3 and Cys9. It is found in crustaceans and insects where it behaves as a cardioaccelerator, neuropeptide transmitter for other areas of the nervous system and a hormone.

Chrysophanol 8-O-β-D-(6’-O-galloyl)glucopyranoside, an anthraquinone glucoside, can be isolated from Rheum undulatum L. Chrysophanol 8-O-β-D-(6’-O-galloyl)glucopyranoside has potent DPPH radical and ?O2- scavenging activity.

1-O-galloyl-6-O-cinnamoylglucose is a natural product for research related to life sciences.
