Brazilian Archives of Biology and Technology , 2002, DOI: 10.1590/S1516-89132002000100012
Abstract: the fruit of schinus terebinthifolius raddi is a globose red drupe with friable exocarp when ripe and composed of two lignified layers: the epidermis and hypodermis. the mesocarp is parenchymatous with large secretory ducts associated with vascular bundles. in the mesocarp two regions are observed: an outer region composed of only parenchymatous cells and an inner region, bounded by one or more layers of druse-like crystals of calcium oxalate, composed of parenchymatous cells, secretory ducts and vascular bundles. the mesocarp detaches itself from the exocarp due to degeneration of the cellular layers in contact with the hypodermis. the lignified endocarp is composed of four layers: the outermost layer of polyhedral cells with prismatic crystals of calcium oxalate, and the three innermost layers of sclereids in palisade.

Abstract: the etoh extract from the leaves of schinus terebinthifolius showed anti-radicalar potential in the dpph test. it was partitioned between n-buoh:h2o (1:1) and these two phases were also evaluated for anti-radicalar activity. the active n-buoh phase was partitioned between etoac:h2o (1:1) and the active etoac phase was submitted to chromatographic procedures to afford five active phenolic compounds: ethyl gallate, methyl gallate, quercitrin, myricetrin and myricetin. the structures of these compounds were established by nmr spectral data analysis.

Biotemas , 2004,
Abstract: Schinus terebinthifolius Raddi is a brazilian native dioecious species of Anacardiaceae with a wide geographical distribution and great ecological plasticity. The studywas carried out in a sandbank area, in the municipal district of Florianópolis-SC, from September 2002 to May 2003. Analysis of the flower morphology of both sexes, measures of the inflorescence lengths and widths, counting of the inflorescence numbers per branchs and flowers per inflorescence, as well as the daily number of opened flowers, were all performed with the aim of detecting a probable reproductive dimorphism. The results obtained in the present study demonstrate that the studied plant present diclinous flowers depending basically on insects for pollination. Anthesis occurs always in the morning and the male flower has a duration of only 12 hours, while the female flower remains receptive for a period of more than 32 hours. In the 1st reproductive period of the study (springtime), just 22% of the plants were blooming. In the 2nd period (summer/autumn), 100% of the individuals were blooming. The species presented sexual dimorphism, manifested by the length (t= -12.75; p<0.5) and (t= -11.78; p<0.5) of their inflorescence. However, the similarities between their flowers, added to the synchrony of their reproductive period, the anthesis and availability, in both sexes, seem to attenuate the differences and possibly favor reproductive success through the attraction of floral visitors to both types of flower.

Abstract: the essential oil of schinus terebinthifolius (anacardiaceae) was analyzed by gc and gc-ms. α-fenchene, limonene, β-pinene, α-phellandrene, and β-isosylvestrene represent about 80% of the oil composition. the reproductive toxicity of the essential oil in wistar male rats was evaluated. no changes were observed in the mass of the reproductive organs, number and morphology of spermatozoa, reproductive rates, and the body mass of offspring of male rats after treatment with the essential oil of s. terebinthifolius.

Abstract: essential oils of ripe fruits from schinus terebinthifolius (anacardiaceae), obtained using a pilot extractor and a clevenger apparatus were chemically characterized. due the high amount of (-)- α-pinene in both oils, this monoterpene was tested against the protozoan parasite trypanosoma cruzi, showing a moderate potential (ic50 63.56 μg/ml) when compared to benznidazole (ic50 43.14 μg/ml). otherwise, (-)- α-pinene oxide did not showed anti-trypanosomal activity (ic50 > 400 μg/ml) while (-)-pinane showed an ic50 of 56.50 μg/ml. the obtained results indicated that the epoxydation of α-pinene results to the loss of the anti-parasitic activity while its hydrogenation product, contributed slightly to the increased activity.

Abstract: the effect of soil polluted by diesel oil on the germination of seeds and the growth of schinus terebinthifolius raddi seedlings was analyzed at different times after contamination of the soil. the experiments were conducted under greenhouse conditions, with four treatments and five repetitions. the four treatments included: soil contaminated 30 (t30), 90 (t90) or 180 (t180) days before planting as well as a non-polluted soil (t0) (control). soil saturated to 50% of its maximum retention capacity (mrc) was contaminated with diesel oil at a rate of 92.4 ml per kg. the germination rate and germination speed index (gsi) were significantly affected only in t30. the development of the plants was affected significantly in all the treatments, with reductions of biomass and eophyll area. it could be concluded that diesel oil significantly affected the germination, gsi and seedling growth of s. terebinthifolius, but the toxic effect decreased over the time.

Abstract: the secreory cavities in fruits of schinus terebinthifolius raddi were studied by optical and electron microscopy. these are complex cavities with a multistratified epithelium, surrounding a lumen filled with whole cells and viscous fluid. each cavity is surrounded by two or three layers, radially flattened cells, which will progressively mature into epithelial cells. the secretory cavities initiate schizogenously and develop schizolysigenously. the lumen appears by the dissolution of the middle lamela in a group of precursor cells arranged in a rosette, and widens by the separation of the inner cells of this rosette. the young epithelial cells have dense cytoplasm with large mitochondria, extensive rough endoplasmic reticulum, numerous multivesicular bodies, and modified plastids. clumps of electron-dense material without a delimiting membrane occur the peripheral cytoplasm, periplasmic space, and scattered in the cavity lumen. as differentiation progresses, the innermost epithelial cells are continuously released into the lumen and degenerate. lysigeny of these cells contributes with materials to secretion, also leading to cavity enlargement. optical and ultastructural data indicate that secretion elimination occurs by ecrine and holocrine mechanisms.

Abstract: reproductive phenology, floral morphology and the reproductive system of schinus terebinthifolius were investigated in two physiognomies of restinga vegetation at grussai/iquipari, rio de janeiro, from january to december/2004. schinus terebinthifolius had cornucopia flowering strategy, with two flowering peaks during the year, both in the rainy season; fruit was set in the dry period. morphological analysis of the flowers and pollination experiments confirmed dioicism and obligatory xenogamy in this species. high synchrony between male and female plants occurred, an important strategy for dioecious species. no difference in fruit set was found between natural and cross pollinations in the two physiognomies studied, indicating lower values than those observed in others studies.

Abstract: schinus terebinthifolius fruit contains a single seed that is reniform, with a smooth pale-brown membranaceous seed coat, and a small dark brown saddle-shaped patch. it is an exalbuminous seed and the reserve foods in the cotyledons are proteins and lipids. the ovule is anatropous, bitegmic, crassinucellar with well developed rafe, inserted in an apical-lateral position in the fruit. the outer tegument is continuous with the base of the funicle and has been interpreted as a partially tegumentar funicular obturator. the hypostase is tanniferous and results from the chalazal and nucelar tissues. the presence of remains of the funicle fused to the seed-coat is considered a vestigial aril. the seed-coat has double origin: a partially pachychalazal one, externally evident in the mature seed, as a small dark brown saddle-shaped patch, and another one of tegumentary origin.
