✦ Synopsis
Abstract
Three new iridoid glycosides, hedycorysides A–C (1–3, resp.), were isolated from the whole plant of Hedyotis corymbosa (Linn.) Lam., along with four known compounds. Their structures were elucidated by extensive 1D‐ and 2D‐NMR analysis, as well as by HR‐ESI‐MS experiments. The three new compounds are the first benzoylated geniposide derivatives from Hedyotis.
