Martins, Ernane R.;Casali, Vicente W. D.;Barbosa, Luiz C. A.;Carazza, Fernando;
Journal of the Brazilian Chemical Society , 1997, DOI: 10.1590/S0103-50531997000100006
Abstract: chemical composition analysis of the essential oil from the leaves and flowers of two accessions of ocimum selloi benth, cultivated at the federal university of vi?osa was carried out. for accession a the major component was identified as estragole and represented 94,95% and 92,54% of the oil from the leaves and flowers respectively. for accession b, the oil from the leaves and flowers was constituted by 65,49% and 66,18% of methyleugenol, respectively. for both accessions several minor constituents were also identified. the phenotypic and chemical differences observed between these two accessions suggest the existence of two chemicaly distinct varieties for ocimum selloi benth.

Abstract: ocimum selloi benth, a native plant of brazil, has medicinal uses as anti-diarrheic, antispasmodic and anti-inflammatory product. the yield of essential oils of the inflorescences, containing flowers and seeds, was 0.6%, and the yield of leaves, collected in two different seasons, was 0.25% (june 2000) and 0.20% (january 2001), respectively. the essential oils of the inflorescences and leaves presented as major constituents trans-anethol (41.34%, 45.42%, 58.59%) and methyl chavicol (27.10%, 24.14%, 29.96%).

Abstract: the present study was undertaken to develop the proliferation of sprouts in apical and nodal segments of ocimum selloi with different bap levels. young plants aged 60 days were used as donors of nodal and apical segments. the segments were inoculated in ms medium at half the concentration of salts supplemented with 1.5% of sucrose and different bap levels. the experiment was in 3 x 4 factorial arrangement, 3 positions of o. selloi segments (apical segment; first and second nodal segment) and 3 bap levels (0 - control; 2; 4 and 6 mg l-1). after 30 days, the number, the length, and the fresh and dry biomass of sprouts and roots were evaluated. the first and the second segments showed better results in inducing o. selloi sprouts, 7 and 8 sprouts/explant, at the different bap levels, but there was not root formation in the presence of the cytokinin. under the tested conditions, use of the first and the second nodal segments is recommended in addition to supplementing the culture medium with bap for in vitro proliferation of o. selloi sprouts.

Abstract: this work describes the chemical composition and antimicrobial activity of the volatile oils of ocimum canum and ocimum selloi, both occurring in jequié/ba, northeastern brazil. the plants were collected in the winter/2005 andsummer/2006, the oils extracted by steam distillation and further analyzed by gc-ms. a total of 30 and 31 compounds was identified from the oils of o. selloi and o. canum, respectively. it was observed that the oil content of o. canum showed variation during the seasons, while the oils of o. selloi did not. methylchavicol and linalool were the main chemical components found in the aerial parts and leaves of o. canum. this finding permitted to characterize this specimen as a new chemotype of o. canum. regarding the aerial parts of o. selloi, eugenol, 1,8-cineole, transcaryophyllene and linalool were identified as their major components. all extracted oils from the aerial parts showed biological activity against gram-positive cocci - staphylococcus aureus atcc 25923 - but only the o. canum one showed activity against gram-negative bacilli - escherichia coli atcc 25922.

Abstract: ocimum selloi benth. (lamiaceae) is native to south america and in traditional medicine has been used due to its analgesic, anti-inflammatory, and antispasmodic properties. the aim of this study was to identify the types of glandular trichomes that occur on the vegetative and reproductive organs of o. selloi and to determine trichome ontogeny. lateral branches at the initial formation phase, fully opened leaves, flowers at different differentiation stages, and stem and inflorescence axes were analyzed under light and scanning electron microscopy. glandular trichomes of the peltate and subsessile capitate types were observed on the stem, leaves, inflorescence axis and the adaxial surface of the sepals. on the sepals, in addition to the peltate and subsessile capitate secretory trichomes, the stalked capitate glandular trichome type was detected. ontogeny began with the expansion of a protodermic cell, which according to the sequence of periclinal and anticlinal division (either symmetric or asymmetric) gave rise to the glandular trichomes. differentiation of the peltate and capitate glandular trichomes was not synchronized and occurred very early in the leaf, stem and floral axis.

Abstract: among the medicinal plants native to brazil, ocimum selloi benth., an herbaceous annual plant of the lamiaceae family, occurs in the southeastern and south regions of the country. this work evaluated flower biology aspects (flower structure, flowering and fructification) and reproductive mechanisms of four o. selloi populations from piquete and apiaí regions, s?o paulo state; camanducaia, minas gerais state; and colombo, paraná state. anthesis started at 11:00 a.m. and finished at 3:00 p.m., with flowering climax at 1:00 p.m., and temperature was slightly important in this process. pollen viability was high in all four studied populations. this species is self-compatible, forming fruits and seeds under both free pollination and spontaneous self-pollination, which indicates it has a great reproductive versatility, assuring genetic variability. seed germination was also high in all four populations.

Abstract: "atroveran" or "elixir-paregórico" (ocimum selloi benth.) is a brazilian species that produces an essential oil rich in methyl chavicol. this work aimed to evaluate the influence of light, temperature and time of storage in different environments on the germination and vigor of o. selloi seeds. we initially tested the influence of presence and absence of white light in a 12-hour photoperiod to determine the photoblastism of the seeds under different temperatures (20, 25, 30 and 35oc). the physiological quality of seeds conserved under two temperatures (room temperature and cold chamber) was tested at 0, 2, 4, 6, 8 10 and 12 months of storage. the species was classified as neutral photoblastic with germination at a wide temperature range (20oc-30°c). germination was maintained for twelve months of storage in cold chamber at room temperature, but the vigor was reduced in seeds kept at room temperature after the sixth month of storage.

Abstract: This paper aimed to list the community of floral visitors of Ocimum selloi, indicate the potential pollinators, and their patterns of visitation. The collection of flower visitors was carried out in 2007, in an anthroposophical area, with analysis of constancy and dominance of taxa. A total of 653 insects was collected, belonging to seven orders; Hymenoptera, with 370 individuals, was the most representative group. Thirty six families were identified, being 12 of Hymenoptera and eight of Diptera the most diverse ones. Apidae was the family which showed the greatest constancy and dominance, especially through the bee Apis mellifera L., 1758 (n = 223), followed by Halictidae (n = 107). Most of the foraging activity was observed between 9a.m. and 11a.m. It was found that A. mellifera was the main floral visitor and potential pollinator of O. selloi.

Abstract: the aim of this work was to avail the effect of different manures in association or nor with green manure on yield of leaves of ocimum selloi benth. the assay was accomplished on experimental area of embrapa environmental (jaguariúna district), at two different spaces (with or without green manure crotalaria juncea). the treatments used were t1 - witness (no manure), t2 - chicken manure (5 kg m-2), t3 - commercial product fishfértil - 5 ml m-2) and t4 - composting (4 kg m-2). the cut was realized on 180 days after the planting (january - 2011), and were collected four plants/ plot. the yield of dried and fresh ocimum selloi phytomass was availed. the experimental design was factorial scheme (2x4), with four repetitions. the treatment with chicken manure showed best results on ocimum selloi leaves yield than the others treatments, but did not was influence by using crotalaria juncea.
