Flavonol glycosides from .

Two new flavonol glycosides, fissmacosides A (1) and B (2) along with two known flavonol glycosides, kaempferol 3--l-rhamnopyranosyl-(1→6)--d-galactopyranoside (3) and kaempferol 3--d-glucopyranosyl-(1→4)--l-rhamnopyranosyl-(1→6)-[4-()-feruloyl]--d-galactopyranoside (4) were isolated from the methanol extract of the leaves of Merr. Their structures were determined on the basis of extensive spectroscopic methods, including 1D-, 2D-NMR, and MS data.

Prevalence and correlates of multimorbidity among adults in border areas of the Central Highland Region of Vietnam, 2017.
