Effect of Seed Oil and Methanol Leaf Extract of Dialium guineense Steud on Wound and Inflammation

These ingredients are all derived from hazelnut trees. The two seed oils are expressed from the nuts of the hazelnut tree of the particular species identified. Most current reported cosmetic uses are of the seed oils. The seed extracts are the extract of the nuts of the identified species tree. There is one current report of use of seed extract in cosmetics. The leaf extracts are the extract from the leaves of the particular species tree. There are no current reports of use of these extracts in cosmetics. Analysis of seed oil from one species identified Oleic Acid, Palmitoleic Acid, Linoleic Acid, Eicosaenoic Acid, Docosenoic Acid, Eicosanoic Acid, Palmitic Acid, Linolenic Acid, Stearic Acid, and Tetraeicosanoic Acid. Little information is available to characterize the extracts, however. The functions of most of these ingredients in cosmetics are not reported. In studies of hazelnuts from Spain and Egypt, aflatoxin was reported as a possible contaminant. Aflatoxins are considered carcinogenic in humans. Virtually no safety test data are available on these ingredients. Negative results in one comedogenicity study using a seed oil are reported. Cross-sensitivity to proteins in peanuts and those in hazelnuts are reported, but the presence or absence of protein in nut extract and plant extract from hazelnut trees is not known. Additional data were provided regarding concentration of use, method of extraction and contaminants, comedogenicity, and ultraviolet (UV) radiation absorption, but these data related to nut oil from only one species, and were not overall sufficient to resolve questions about irritation, sensitization, and photosensitization. Because of the absence of data, it is concluded that the available data are insufficient to support the safety of these ingredients in cosmetic products. Because of the limited information that characterizes any of these oils or extracts, data are needed on each (except that items 1, 2, and 3 below are not needed for Hazel [Corylus Avellana] Nut Oil). The additonal data needs include: (1) current concentration of use; (2) method of extraction/manufacture and quality control (i.e., chemical analyses); (3) contaminants and methods of extraction (especially pesticides and heavy metals); (4) dermal irritation and sensitization; (5) UV absorption; if there is significant absorption, then a photosensitization study will be needed; (6) 28-day dermal toxicity; (7) reproductive and developmental toxicity; and (8) two genotoxicity assays, one in a mammalian system; if positive, then a 2-year dermal carcinogenesis study using National Toxicology Program (NTP) methods may be needed.

Antibacterial And Antifungal

The study on antibacterial and antifungal efficacy of leaf and seed extract and seed oil of Jatropha curcas reveals that the inhibition zones ranged from 7 to 22 mm for antibacterial and from 10 to 20 mm for antifungal activity. Among all extracts tested, seed extract showed significant activity while leaf extract showed intermediate activity against gram-positive bacteria. In case of gram-negative bacteria, seed extract and seed oil has shown some moderate activity whereas, no activity was observed in leaf extract. In case of fungal cultures, among all test extracts only seed extract showed significant activity against Mucor and Tilletia fungus, while in case of Rhizopus no activity was observed against all test extracts. These results indicated the possibility of using Jatropha extract and seed oil for medicinal uses and natural food preservation.

Dipteryx Odorata

O cumaru (Dipteryx odorata (Aubl.) é uma leguminosa da família Fabaceae, suas sementes são muito utilizadas na extração do óleo, o qual é bastante utilizado pela medicina popular como antiespasmódico, tônico, anti-inflamatório, reumatismos e antimicrobiano. A cumarina está presente na semente e também em toda a extensão da planta. O objetivo deste trabalho foi obter o óleo da semente e o extrato de folhas, realizar ensaios biológicos com o extrato e elaboração de um produto biotecnológico. O estudo foi realizado no laboratório de Química Orgânica da Universidade Federal do Amazonas, no qual as sementes foram coletadas, maceradas, para extração do óleo, em seguida, se realizou análise por cromatografia de camada delgada (CCD) do óleo da semente. As folhas foram maceradas, e preparadas as exsicatas, utilizou-se o óleo na produção do produto e para os ensaios biológicos frente às bactérias: Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae. Os resultados obtidos da extração das sementes foram o óleo e os cristais brancos em forma de agulha. Após análises cromatográficas (CCD) do extrato das folhas foi possível observar a presença de cumarina. O ensaio biológico com os cristais frente às bactérias S. aureus, E. coli, K. Pneumoniae apresentou halo de inibição. Assim, o óleo e a cumarina presentes na semente podem atuar como antibacteriano natural para o tratamento de várias doenças infecciosas causadas pela bactéria S. aureus. Foi possível formular um creme hidratante incorporando o óleo obtido da semente. Palavras-chave: Extração do Óleo. Cumarina. Produto Biotecnológico. Abstract Coumaru (Dipteryx odorata (Aubl.) is a legume of the Fabaceae family, its seeds are widely used in oil extraction, which is widely used by folk medicine as an antispasmodic, tonic, anti-inflammatory, rheumatism and antimicrobial. Coumarin is present in the seed and also in the entire length of the plant. The objective of this work was to obtain the seed oil or the leaf extract, to perform biological tests with the extract and to elaborate a biotechnological product. The study was carried out in the Organic Chemistry laboratory, where the seeds were collected, macerated, for oil extraction, then a CCD analysis of the seed oil was carried out, the leaves were macerated, and the exsiccates were prepared, the oil was used in the product production and for biological tests against bacteria: Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae. The results obtained from the seeds extraction were oil and white crystals. After a chromatographic analysis (CCD) of the leaf extract, it was possible to observe the presence of coumarin. The biological assay with the crystals against the bacteria S. aureus, E. coli, K. Pneumoniae showed an inhibition halo. Thus, the oil and coumarin present in the seed can act as a natural antibacterial for the treatment of various infectious diseases caused by the bacteria S. aureus. It was possible to formulate a moisturizing cream incorporating the oil obtained from the seed. Keywords: Cumaru Oil Extraction. Coumarin. Biotechnological Product.

Neem Seed Oil

Soybean (Glycine max L., Variety PB-1) is an important oilseed crop though not extensively cultivated in Bangladesh. Five different plant extracts i.e., Bara Bishkatali leaf extract, sesame seed oil, castor seed oil, a mixture of sesame oil and neem seed oil and tobacco leaf extract were sprayed prior to pest infestation. The major insect pests encountered were the leaf roller (Sylepta derogata), pentatomid bug (Nezara viridula and Piezodorus hybneri), noctuid semilooper (Trichoplusia ni) and blue butterfly (Euchrysops cnejas). Among the applied treatments, tobacco leaf extract showed the best result followed by Bara Bishkatali leaf extract, sesame seed oil and a mixture of sesame oil and neem seed oil and castor oil. Some unidentified beneficial eurytomid, braconid, ichneumonid and encyrtid insect parasites and coccinellid predators played an important role in suppressing the pest population during the study period. The maximum yield was 36.7 maunds per acre in the BCSIR Laboratories Campus, Rajshahi but the yield was only 3 maunds per acre in the Oilseeds Cultivation Centre Patgram, Lalmonirhat. Bangladesh J. Sci. Ind. Res. 41(1-2), 73-76, 2006
