Antifeedant diterpenoids against Tribolium castaneum from the stems and twigs of Ceriops tagal (Rhizophoraceae).
The screening of several Chinese mangrove plants for insecticidal principles showed that ethanol extract of Ceriops tagal stems and twigs possessed significant feeding deterrent activity against the red flour beetle, Tribolium castaneum (Family: Rhizophoraceae). From the ethanol extract, three feeding deterrent diterpenoids were isolated by bioassay-guided fractionation. The compounds were iden...
متن کاملAntifeedant Activities of Lignans from Stem Bark of Zanthoxylum armatum DC. against Tribolium castaneum.
The speciation of a methanolic extract of Zanthoxylum armatum stem bark has enabled the isolation and characterization of 11 known lignans. Among them, five compounds (6, 8-11) are reported in this plant for the first time. All of the chemical structures were elucidated on the basis of NMR spectral analysis. Additionally, their antifeedant activities against Tribolium castaneum were evaluated s...
متن کاملSpatial and Temporal Regeneration Dynamics in Ceriops tagal ( Perr.) C.B. Rob. (Rhizophoraceae) Mangrove Forests in Kenya
Mangrove forests consist of a mosaic of tree cohorts, each having a regeneration history that depends on episodic recruitment of seedlings based on the availability of a “regeneration niche”. The aim of this study was to assess seedling population structure in Ceriops tagal natural monospecific stands and one eight-year old reforested stand at Gazi Bay, Kenya, to determine performance in terms ...
متن کاملDammarane triterpenes from the hypocotyls and fruits of Ceriops tagal.
Three new dammarane triterpenes, cereotagaloperoxide, cereotagalol A, and cereotagalol B, together with four known dammarane triterpenes, an oleanane triterpene, and 13 known lupane triterpenes were isolated from the hypocotyls and fruits of Ceriops tagal. The structures of 1-3 were characterized on the basis of their spectroscopic data.
متن کاملAntifouling metabolites from the mangrove plant Ceriops tagal.
The new diterpene methoxy-ent-8(14)-pimarenely-15-one (1) and three known metabolites: ent-8(14)-pimarene-15R,16-diol (2), stigmasterol (3) and beta-sitosterol (4), were isolated from the roots of the mangrove plant Ceriops tagal. Their structures and relative stereochemistry were elucidated by means of extensive NMR, IR and MS analysis. Compounds 1, 2, 3 and 4 exhibited significant antifouling...
