Phytochemical Study of Glycosmis Mauritiana  [PDF]
Javed Intekhab, Mohammad Aslam, Hira Khalid
American Journal of Plant Sciences (AJPS) , 2011, DOI: 10.4236/ajps.2011.25078
Abstract: Three quinolinone alkaloids, two acridone alkaloids and a flavones glycoside were isolated from the aerial parts of Glycosmis mauritiana. These compounds were characterized as 7, 8-Dimethoxy-2,2,6-trimethyl-pyrano quinolin-5-one, 4-Methoxy 1-methyl quinolin-2-one, 6-Hydroxy N-methyl 2,3-furo-quinolin-4-one, 1-Hydroxy-10-methyl acridone, 1- Hydroxy-2, 3-dimethoxy-10-methylacridin-9-one and Luteolin-4'-O-[α-L-rhamnopyranosyl-(1→2)-{α-L-rhamnopyra- nosyl-(1→6)}-β-D-glycopyranoside]. The isolated compounds were characterized by UV, IR and N. M. R (1H, 13C) studies.

Bioagro , 2005,
Abstract: azahar of india (murraya paniculata) is widely cultivated as ornamental plant. its propagation at commercial level has been done by seeds, but the plants show very slow growth, taking a long time for transplanting; the asexual propagation has been difficult. the present study was conducted in order to evaluate the effect of four concentrations of aib (0, 3000, 4000 and 5000 m g·g-1) on rooting when using air layering propagation. after 60 days 100% of rooting was obtained in all treatments, but the concentration of 4000 m g·g-1 produced the highest fresh and dry mass, number and total length of roots.

Pollen morphology of species of Hortia (Rutaceae)
Groppo, Milton;Cruz-Barros, Maria Amélia Vitorino da;Correa, Angela Maria da Silva;
Brazilian Journal of Botany , 2010, DOI: 10.1590/S0100-84042010000100003
Abstract: a palinological study covering all 10 species of the neotropical genus hortia vand. (rutaceae) was conducted. pollen grains were collected from herbarium exsiccates, acetolysed and mounted in glycerine jelly on glass slides. the grains were studied under light and scanning electron microscopy, including measurements of polar and equatorial diameters, shape of the grains, number and shape of apertures, and thickness of the exine. the results demonstrated that the genus is stenopalynous, with pollen grains in monads, subprolate to prolate, 3-colporate, with very thick exine and a psilate-perforate pattern of ornamentation. pollen grains of all species revealed a great similarity, with few variations in the pattern of ornamentation of exine, number and form of apertures and measurements. although well-characterized palinologycally, pollen features did not furnish relevant information on the position of hortia into an intrafamilial phylogeny.
Hortia brasiliana Vand. (Rutaceae): poliniza??o por aves Passeriformes no cerrado do sudeste brasileiro
BARBOSA, ANA ANGéLICA ALMEIDA;
Brazilian Journal of Botany , 1999, DOI: 10.1590/S0100-84041999000100013
Abstract: hortia brasiliana vand. (rutaceae) is a common shrub found in cerrado areas of uberlandia, mg, brazil. individuals are 0.5 to 2.0 m high, with rose-coloured and coriaceous flowers, displayed in dense inflorescences. the anthesis occurs along the day or night and can take from 25 min. to 3 hours to complete, according to the temperature. the flower is protandrous and produces an average of 60 μl of nectar, with sugar concentrations ranging from 24 to 32%. the species is self-compatible. flowers are visited by six passeriform birds belonging to the fringillidae, thraupidae and mimidae families, considered effective pollinators. this pollination type is new for cerrado vegetation. birds were observed visiting the flowers to obtain nectar from 4:30 a.m. to 8:30 a.m., when they were sent away by trigona spinipes bees (apidae). in order to visit the plant, the birds use the inflorescence as a landing platform, probing 15 to 25 flowers per visit without flight incursion. the permanence period of a bird in a particular plant depended on the arrival of other individuals, and all bird species showed agonistic behaviour when other birds landed on the same plant. pollination was carried out when the stigma got in contact with body parts in which sticky pollen was adhered to. among the bees, trigona spinipes was the most regular visitor, its activity taking place from 8:30 a.m. to 5 p.m. bees remained in the same inflorescense for a long time performing selfing and geitonogamous pollination. xylocopa aff. hirsutissima was less common than trigona spinipes, but due to its behaviour on inflorescences, contacting the stigma and the anther, and its larger size as compared to trigona, it was considered an additional pollinator. other visitors (wasps, butterflies, flies, and ants) were considered nectar robbers, occasionally able to perform pollination.

Nascimento, Eduardo Tigre do;Pérez-Maluf, Raquel;Guimar?es, Rosimeire Alves;Castellani, Maria Aparecida;
Revista Brasileira de Fruticultura , 2011, DOI: 10.1590/S0100-29452011005000048
Abstract: the presence of bees on cultures with commercial value during flowering is important to ensure the cross-pollination, when necessary, but also to increase the production of fruits and seeds. this work aimed to identify flowers' visiting bees on orange and tangerine orchards in salinas - mg. the work was leaded on santa isabel experimental farm of the federal agro-technical school of salinas - mg, on orange orchards (citrus sinensis) with pear, bahia and baianinha varieties in the spacing of 5,0 x 6,0, and on tangerine orchards (c. reticulate) using ponc? variety in the spacing of 5,0 x 5,0. the sampling of visiting bees from orange and tangerine orchards was made during the main flowerings, between august and october. the bees that visited the flowers between 06:00 a.m. and 06:00 p.m. were collected. 5045 bees were collected with richness of 12 species in orange and 1428 bees with richness of 20 species in tangerine. the species of bees with major predominance and dominance in all sampled times were apis mellifera and trigona spinipes (orange) and apis mellifera, trigona spinipes e tetragonisca angustula (tangerine).
ISOLATION OF A FLAVONOID FROM THE ROOTS OF CITRUS SINENSIS
JAVED INTEKHAB,MOHAMMAD ASLAM
Malaysian Journal of Pharmaceutical Sciences , 2009,
Abstract: Citrus sinensis is native to Asia and throughout the Pacific and warm areas of the world. The ethyl acetate extract of the roots of Citrus sinensis yielded a flavonoid. The compound was characterizedas 5, 8-dihydroxy-6, 7, 4′-trimethoxyflavone on the basis of UV, I.R, mass and N.M.R (1H, 13C) spectral studies. We believe this is the first report describing the isolation of flavonoid from thisplant.
