Abstract

A rare noriridoid and six known phenolic compounds were isolated from the parasite plant Rhopalocnemis phalloides. Using spectroscopic methods, these compounds were identified as 10-acetoxy-cis-2-oxabicyclo[4.3.0]nonan-7-en-3-one (1), p-hydroxybenzoic acid (2), protocatechuic acid (3), gallic acid (4), coniferyl aldehyde (5), l-O-trans-cinnamoyl-β-D-glucoside (6), and coniferin (7). The noriridoid compound is the first reported from the family Balanophoraceae. Of the isolated compounds, coniferyl aldehyde had the strongest inhibitory effect on nitric oxide production (IC₅₀ = 8.24 μM).
