Enhancing polyphenol synthesis and antioxidant activity in Camellia sinensis using shikimic and salicylic acids

JSFA reports, EarlyView.
Abstract Background Camellia sinensis, widely consumed as tea, is the second most popular beverage globally and is valued for its health benefits. However, environmental stressors pose a significant challenge to the tea industry. This study investigates the potential of shikimic acid (ShA) and its derivative, salicylic acid (SA), as inducers to enhance

Formation of bilirubin glucoside [PDF]

Biochemical Journal, 1971
1. Rat liver microsomal preparation can effect the transglucosylation from UDP-glucose to bilirubin in the presence of Mg2+. 2. Other nucleotides, namely CDP-glucose, ADP-glucose and GDP-glucose, were not active as glucosyl donors. 3. Only trace amounts of galactose, galacturonic acid and N-acetylglucosamine were conjugated to bilirubin when their ...

Molecular characterization and structure basis of a malonyltransferase with both substrate promiscuity and catalytic regiospecificity from Cistanche tubulosa

Acta Pharmaceutica Sinica B
Enzymatic malonylation of natural glycosides provides a promising alternative method for drug-like malonylated glycosides supply. However, the catalytic potential and structural basis of plant malonyltransferase are far from being fully elucidated.

Studies on Monoterpene Glucosides. VII. Iridoid Glucosides of Paederia scandens

Chemical and Pharmaceutical Bulletin, 1969
Four new glucosides, paederoside (II), paederosidic acid (III), scandoside (IV) and deacetylasperuloside (V) along with asperuloside (I) were isolated as iridoid glucosides from Paederia scandens (LOUR.) MERRILL var. mairei (Leville) HARA and their structures were established. II and III are sulfur-containing glucosides.
