Summary The neotropical genus Ruagea H.Karst. is revised. Fifteen species are recognised, including three R. obovata T.D.Penn., beckii T.D.Penn. and parvifructa which described as new to science. A key the presented, along with information on morphology, distribution, ecology, conservation assessments, local names, uses field characters. All mapped illustrated line drawings all specimens seen c...

the fruit of melia azedarach l. (meliaceae) was extracted with hexane, and its fatty acids methyl ester was analyzed using gc/ms. thirteen components representing 85.1% of the total extract were identified. the major components identified were methyl palmitate (18.8%), methyl linolenate (16.1%) and methyl linoleate (9.8%). the fruits’ extract had a lc50 of 5.5 ppm against the larvae of anophles...

The activities of two triterpenoids, ocotillone and cabraleadiol, and four limonoids, methyl angolensate, 3-deacetylfi ssinolide, 7-deacetoxy-7-oxogedunin, and -photogedunin, isolated from arillus of Carapa guianensis and fruits and seeds of Cabralea canjerana (Meliaceae), were evaluated against the fall armyworm Spodoptera frugiperda. Gedunin was used as a positive control. 7-Deacetoxy-7-oxoge...

Four new compounds, the limonoid 24-epi-melianodiol (8), the tirucallane aglaiodiol (9), and the two cyclopentatetrahydrobenzopyran derivatives pyramidaglain A (11) and B (12) were isolated from the leaves of Aglaia andamanica Hiern (Meliaceae), together with the eleven known constituents beta-sitosterol, beta-sitosterol glucoside, cycloart-23E-ene-3 beta,25-diol (1), three flavonoids 5-hydroxy...

Nimonol (1), a tetranortriterpenoid isolated from the leaves of Azadirachta indica A. Juss (Meliaceae), upon photolysis undergoes both Diels-Alder and ene reactions with singlet oxygen at different sites leading to 14,15,20,21-diepoxy-23-nimonolactone (3), along with nimonolide (4), which have been well-characterised. The novelty of the reported reactions lies in hitherto unreported formation o...

THE ANTILEISHMANIAL ACTIVITY OF THREE ORGANIC SOLVENT EXTRACTS AND WATER RESIDUE OF THE PLANTS: Acacia nilotica (Mimosaceae) (husk), Ambrosia miratima (Astraceae) (aerial shoot) and Azadarichta indica (Meliaceae) (leaves) were tested in vitro against Leishmania donovani promastigotes. The study revealed that the extracts of A. nilotica and A. miratima have effectious antileishmanial activity at...
