title: A phenolic glucoside isolated from Prunus serrulata var. spontanea and its peroxynitrite scavenging activity.
abstract: A new phenolic glucoside (1), pursargentoside, was isolated from the leaves of Prunus serrulata var. spontanea, along with three other known compounds, orobol 7-omicron-glucoside (2), 1beta, 2alpha, 3alpha, 24-tetrahydroxy-urs-12-en-28-oic acid (3), and chlorogenic acid (4). The structure of pursargentoside (1) was identified by spectroscopic data analysis including 1D and 2D NMR spectroscopy, as 2-omicron-beta-(6'-benzoyl)-glucopyranosyl omicron-(Z)-coumaric acid. Compounds 1, 2, and 4 exhibited ONOO scavenging activity, whereas compound 3 was determined to be virtually inactive.
