Phenolic glycosides from Viscum angulatum.
Three new glycosides, pinocembrin 7-O-apiosyl(1-->5)apiosyl(1-->2)-beta-D-glucopyranoside (1), 2',3',4',3' '-tetramethoxy-1,3-diphenylpropane 5',4' '-di-O-beta-D-glucopyranoside (2), and rhamnocitrin 3-O-apiosyl(1-->5)apiosyl(1-->2)-[alpha-L-rhamnopyranosyl(1-->6)]-beta-D-glucopyranoside (3), were isolated from Viscum angulatumalong with viscumneoside V, naringenin, and homoeriodictyol. Their structures were established by spectral and chemical methods.
