Dihydroflavonols from the leaves of Macaranga recurvata and their cytotoxic and antioxidant activities
Three dihydroflavonol derivatives, macarecurvatin A (1), macarecurvatin B (2), and 6,8-diisoprenylaromadendrin (3) have been isolated from the leaves of Macaranga recurvata. The structures of these compounds were determined based on UV, IR, HRESIMS, 1D and 2D NMR data. All of compound isolated were evaluated for their inhibitory effect on scavenging DPPH radical and their growth inhibition on M...
متن کاملDegradation of Tropical Malaysian Peatlands Decreases Levels of Phenolics in Soil and in Leaves of Macaranga pruinosa
Indo-Malaysian tropical peat swamp forests (PSF) sequester enormous stores of carbon in the form of phenolic compounds, particularly lignin as well as tannins. These phenolic compounds are crucial for ecosystem functioning in PSF through their inter-related roles in peat formation and plant defenses. Disturbance of PSF causes destruction of the peat substrate, but the specific impact of disturb...
متن کاملAllelopathic prenylflavanones from the fallen leaves of Macaranga tanarius.
Two new prenylflavanones, tanariflavanones A (1), and B (2), and one known compound, (-)-nymphaeol-C (3), were isolated from the fallen leaves of Macaranga tanarius. Compounds 1 and 2 showed inhibition of radical growth of lettuce seedlings at 200 ppm. Their structures were elucidated primarily by NMR, circular dichroism, and mass spectroscopic methods.
