Antioxidant activity of depsides and depsidones

Phytochemistry, 1994
The antioxidant activity of lichenic metabolites, depsides and depsidones, was assessed by their effects as inhibitors of rat brain homogenate auto-oxidation and beta-carotene oxidation. The results obtained in both systems indicate that lichenic metabolites afford a moderate protection in the microM concentration range. The largest effect was measured

Biosynthesis of Depsides, Depsidones, and Diphenyl Ethers from Fungi and Lichens

Asian Journal of Organic Chemistry
Depsides are natural products derived from (poly)phenolic acid derivatives connected by ester bonds. Recent research has revealed crucial molecular mechanisms and distinctive enzymatic chemistry underlying the biosynthesis of depsides, as well as related natural products, such as depsidones and diphenyl ethers.

Depsides in Sunflower Leaves

Nature, 1966
THIS communication reports our finding of neochlorogenic, isochlorogenic, and 3-O-feruloylquinic acids in the leaves of sunflowers, Helianthus annuus, Russian Mammoth variety. The well-known chlorogenic acid (3-O-caffeoylquinic acid) has been previously found in sunflowers by Urban1 and its presence there has been confirmed by Watanabe et al ...
