Biocatalytic synthesis of quercetin 3-O-glucoside-7-O-rhamnoside by metabolic engineering of Escherichia coli
You are what you eat: Quercetin 3-O-glucoside-7-O-rhamnoside is a rare natural product with potential biological importance. We describe a strategy for the regioselective synthesis of this bisglycoside by feeding quercetin 3-O-glucoside, a naturally abundant precursor, to metabolically engineered Escherichia coli.

Further acylated flavonol bisdesmosides from Sinocrassula indica
Further investigation on the whole herbs of Sinocrassula indica (Crassulaceae) led to the isolation of four new acylated flavonol bisdesmosides, sinocrassosides A13 (1), B6 (2), B7 (3), and D4 (4), together with kaempferol 3-O-β-d-(6-O-acetyl)glucopyranos
