title: Two new compounds from the leaves of Indocalamus latifolius.
abstract: Two new compounds, erythro-syringylglycerol-9-O-trans-4-hydroxycinnamate 7-O-β-d-glucopyranoside (1) and indocalatin A (2), together with three known ones, 5,7,3'-trihydroxy-6-C-β-d-digitoxopyranosyl-4'-O-β-d-glucopyranosyl flavonoid (3), 5,4'-dihydroxy-3',5'-dimethoxy-7-O-[β-d-apiose-(1→2)]-β-d-glucopyranosyl flavonoid (4), and tricin-6-C-β-boivinopyranosyl-8-C-β-glucopyranoside (5), were isolated from the 95% EtOH extract of Indocalamus latifolius leaves. Their molecular structures were determined by UV, IR, HRESIMS, CD, and 1D and 2D NMR data analyses.
