Two New Phenolic Glycosides from Viburnum melanocarpum
Two new phenolic glycosides 1 and 2 were isolated from the ethanolic extract of Viburnum melanocarpum P.S. Hsu and identified as (7R,8S)-syringylglycerol 8- O - β -D-allopyranoside ( 1 ) and (7S,8S)-syringylglycerol 8- O - β -D-allopyranoside ( 2 ). Their structures, including absolute configuration...

were isolated from the ethanolic extract of
Viburnum melanocarpum
P.S. Hsu and identified as (7R,8S)-syringylglycerol 8-

-
β
-D-allopyranoside (
1
) and (7S,8S)-syringylglycerol 8-
O
-
β
-D-allopyranoside (
2
). Their structures, including absolute configurations, were determined by spectroscopic data (
1
H and
13
C NMR, HSQC, HMBC, and ORD) and chemical methods. In addition, compounds
1
and
2
were assayed for their free radical scavenging and α-glucosidase inhibitory activities. |
