The Influence of Light on Synthesis of Protein and of Chlorogenic Acid in Potato Tuber Tissue.
Disks of tuber tissue maintained in a moistened environment increase substantially in both protein content (18, 19, 21) and phenolic content (28). The 2 processes have not previously been considered as related. However, the stimulation by light of phenolic synthesis in tuber slices (11, 16) has been found to depend largely on the synthesis of proteins. Data which relate the production of phenol...
متن کاملAnalytical study of ipomeamarone & chlorogenic acid alterations in sweet potato roots infected by Ceratocystis fimbriata.
Several metabolic alterations have been studied, from biochemical and pathological viewpoints, in sweet potato roots infected by the black rot fungus, Ceratocystis finbriata (2, 11, 13), among which the formation of ipomeamarone is of particular interest. Because this substance is a unique furanoterpenoid produced by host tissues in response to infection, and because it has remarkable biologica...
متن کاملThe isolation of chlorogenic acid from the apple fruit.
Chlorogenic acid, the depside formed by the condensation of caffeic and quinic acids, was first obtained in crystalline form by Gorter (1909) from green coffee beans, although considerably earlier Ludwig & Kromeyer (1854) had noted the presence in the seeds of the sunflower of a compound which was undoubtedly chlorogenic acid. The acid was first thought to be a glycoside of caffeic acid, but Go...
متن کاملChlorogenic acid facilitates root hair formation in lettuce seedlings.
Root hairs, which arise from root epidermal cells, are tubular structures that increase the efficiency of water absorption and nutrient uptake. A low pH (pH 4) medium induced root hair formation in lettuce (Lactuca sativa L.) seedlings, and the decapitation of shoots inhibited root hair formation. The addition of shoot extract to the medium restored root hair formation in the decapitated lettuc...
متن کاملChlorogenic acid and caffeic acid are absorbed in humans.
Chlorogenic acid, an ester of caffeic acid and quinic acid, is a major phenolic compound in coffee; daily intake in coffee drinkers is 0.5-1 g. Chlorogenic acid and caffeic acid are antioxidants in vitro and might therefore contribute to the prevention of cardiovascular disease. However, data on the absorption of chlorogenic acid and caffeic acid in humans are lacking. We determined the absorpt...
