Trans-o-Hydroxycinnamic Acid Glucosylation in Cell-Free Extracts of Melilotus alba
The gIucosylation of trans-o-hydroxycinnamic acid has been demonstrated in cell-free extracts of MeliIotus alba. The reaction requires UDPG, a sulfhydryl compound, and an active extract from sweet clover leaves. The product of the reaction has been tentatively identified as trans-/3-D-glucosyl-o-hydroxycinnamic acid. I N T R O D U C T I O N Low molecular weight phenols which occur in living cel...
متن کاملAbsence of Dominance of the Cu Gene in Influencing o-Hydroxycinnamic Acid Content in Melilotus alba
The average content of o-hydroxycinnamic acid in sweetclover plants of the Cucu genotype was 36% of the level found in CuCu plants. Thus, the level of o-hydroxycinnamic acid in the Fl was more like the content of the cucu parent than that of the CuCu parent, indicating that cu was partially dominant over Cu. The calculated value for the degree of dominance of cu over Cu was +0.299. The partial ...
متن کاملThe biosynthesis of coumarin in Melilotus alba.
Previous investigations have shown that CY4-labeled transcinnamic acid is rapidly converted to o-coumaric acid P-glucoside by shoots of Melilotus alba (white sweet clover) (1) and Hierochlod odorata (sweet grass) (2). This glucoside is then converted to coumarin (l-3), possibly by way of trans-cis isomerization of the glucoside to coumarinic acid P-glucoside. The small amount of radioactivity f...
