Two tetranortriterpenoids, kokosanolide A (1) and C (2) were isolated from the seeds and three onoceranoid-type triterpenoids: kokosanolide B (3), 8,14-secogammacera-7,14-diene-3,21-dione (4) and a 1.5:0.5 mixture of 8,14-secogammacera-7,14(27)-diene-3,21-dione (5) and compound 4 were isolated from the bark of kokossan (Lansium domesticum). Complete 1H- and 13C-NMR data of the triterpenoids 1-5...

The microscopic and macroscopic characters of the leaves, physical constant values, behavior on treatment with different chemical reagents, fluorescence characters under ultra violet light after treatment with different chemical reagents of the powdered leaves of Azadirachta indica A. Juss (Family-Meliaceae) were studies to fix some pharmacognostical parameters.

The small Neotropical genus Mastigimas with five described species is revised. Three new species are added: Mastigimas colombianus sp. n. from Colombia on Cedrela montana, M. drepanodis sp. n. from Brazil (Paraná) on C. fissilis and M. reseri sp. n. from Jamaica collected in light traps.

Plotococcus Miller & Denno is synonymized with Leptococcus Reyne (Coccoidea: Pseudococcidae). The genus is redescribed and the adult female of the type species, L. metroxyli Reyne, is redescribed and illustrated. All species hitherto included in Plotococcus are transferred to Leptococcus as L. capixaba (Kondo) comb. nov., L. eugeniae (Miller & Denno) comb. nov., L. hambletoni (Kondo) comb. nov....

Rohitukine, a chromone alkaloid, possesses anti-inflammatory, anti-cancer and immuno-modulatory properties. It has been reported from four species, belonging to the families, Meliaceae and Rubiaceae. Stem bark of Dysoxylum binectariferum (Meliaceae) accumulates the highest amount of rohitukine (3-7% by dry weight). In this study, we examine the spatial and temporal distribution of rohitukine an...

A fraction of leaf extract isolated from leaves of Azadirachta indica (Meliaceae) was tested for lowering of blood cholesterol level in rats. The extract at a dose of 200 mg/kg i.p. significantly lowered the blood cholesterol level in test animals.
