EFFECT OF FOLIAR SPRAY WITH ZINC, BORON AND MOLYBDENUM ON THE GROWTH, YIELD, ESSENTIAL OIL PRODUCTIVITY AND CHEMICAL COMPOSITION OF ROSEMARY (ROSMARINUS OFFICINALIS, L.) PLANT.

This experiment was carried out in Medicinal and Aromatic Plants Research Station at EL-Kanater EL-Khayria, Horticultural Research Institute, Agricultural Research Center, in two successive seasons; 1998 and 1999. The trace elements used in this experiment were Zn, B and Mo. Zn or B used at the rates of 0, 25, 50 or 100 ppm, while Mo at 0, 5, 10 or 20 ppm. The plants were treated with the microelements as foliar spray on April 22nd, July 7th and October 23rd. The obtained results can be summarized as follows: Spraying the plants with B at 100 ppm resulted in the greatest plant height and number of branches/plant as well as oil percentage in herb and leaves and N, K and B content in the herb. It increased herb and leaves fresh and dry weight/plant, oil yield of herb and leaves/plant as well as total carbohydrates, chlorophylls (a, b and total), carotenoids, P, Zn and Mo contents in the herb. Treating the plants with B at 50 ppm increased the vegetative growth, leaves and herb oil % and oil yield/plant, chlorophylls a, b and total, carotenoids, total carbohydrates content, N, Zn, B and Mo in the herb. Using B at 25 ppm led to an increase in the vegetative growth, oil% and yield in leaves and herb/plant, chlorophylls a, b and total, carotenoids, total carbohydrates content, Zn, B and Mo in the herb. However, it decreased P% in both seasons, compared to control plants. Supplying the plants with Zn at 50 ppm resulted in the highest P% in the herb. It increased the vegetative growth as well as oil% and oil yield in herb and leaves/plant. It increased chlorophylls a, b and total, carotenoids, total carbohydrates content, N, P, Zn, B and Mo in the herb, compared to control plants. Application of Zn at 25 ppm resulted in an increase in plant height, oil% in the leaves, oil yield in leaves and herb/plant, total carbohydrates, chlorophylls a, b and total, K%, Zn, B and Mo content in the herb. However, it decreased herb and leaves fresh and dry weight/plant in comparison with untreated plants. Application of Zn at 100 ppm led to an increment in number of branches/plant, total carbohydrates, chlorophylls (a, b and total), carotenoids, N, Zn and B contents. While, it decreased plant height, leaves and herb fresh and dry weight/plant, oil% in leaves, oil yield of leaves and herb/plant and P % compared to control plants. Application of Mo at 10 ppm led to the greatest fresh and dry weights of leaves and herb/plant as well as oil yield of herb and leaves/plant, also total carbohydrates content in the herb. It increased plant height, number of branches/plant, oil percentage in both herb and leaves, N, K, Zn, B and Mo in the herb, chlorophylls (a, b and total), carotenoids content. It decreased P content in the herb, compared to untreated plants. Spraying the plants with Mo at 5 ppm caused an increase in plant height, leaves and herb fresh and dry weights/plant, as well as oil% and yield of leaves and herb/plant, chlorophylls (a, b and total), carotenoids, Zn and B contents. However, P and K% in both seasons were decreased compared with control plants. Treating the plants with Mo at 20 ppm decreased all vegetative characteristics and the chemical determinations, except chlorophylls (a, b and total), carotenoids, Zn, B, and Mo contents which were increased compared to untreated plants.

EFFECT OF PLANTING DISTANCES ON THE GROWTH, YIELD, ESSENTIAL OIL PRODUCTIVITY AND CHEMICAL COMPOSITION OF ROSEMARY (ROSMARINUS OFFICINALIS, L.) PLANT.

This experiment was carried out in Medicinal and Aromatic Plants Research Station at EL-Kanater EL-Khayria, Horticultural Research Institute, Agricultural Research Center, in two successive seasons; 1998 and1999. The aim of this study was to investigate the effect of planting distances on the growth, yield, essential oil productivity and chemical composition of Rosmarinus officinalis, L. plant. The plants of this experiment were cultivated at a distance of 20, 30, 40, 60 or 80 cm between them in the row and 30 cm between the rows. All the plants of this experiment were fertilized with nitrogen (N) at 150 kg, phosphorus (P2O5) at 50 kg and potassium (K2O) at 30 kg/fad. Nitrogen was added in the form of ammonium nitrate (33.5% N), while phosphorus was applied as calcium superphosphate (15.5% P2O5) and potassium as potassium sulfate (48% K2O). The obtained results can be summarized as follows: Growing rosemary plants at 20 cm apart resulted in the tallest plants, while, increasing the distance from 20 to 80 cm decreased steadily plant height. Cultivation at 80 cm between the plants in the row increased the number of branches, fresh and dry weights of herb as well as leaves/plant. Also, the plants which grew at this distance had the highest oil percentages and oil yield in their fresh herb and leaves per plant. Whereas increasing planting distances from 20 to 80 cm increased photosynthetic pigments (chlorophylls a, b and total, as well as carotenoids), total carbohydrates, nitrogen, phosphorus and potassium percentages in the herb in the two seasons. As a general trend, it is very clear that the highest values of all previous parameters were resulted in cultivation at the widest distance (80 cm between the plants in the row). Whereas the lowest values of all previous characters were produced from cultivation at the narrow distance (20 cm between the plants in the row). At the same time the opposite trend was found with plant height in the two seasons.

Gastroprotective effect of an aqueous suspension of black cumin Nigella sativa on necrotizing agents-induced gastric injury in experimental animals

Background/AimPrevious studies on “Black seed” or “Black Cumin” Nigella sativa (NS) have reported a large number of pharmacological activities including its anti-ulcer potential. These studies employed either fixed oil, volatile oil components or different solvent extracts. In folkloric practices, NS seeds are taken as such, in the form of coarse dry powder or the powdered seeds are mixed with water. This study examines the effect of NS aqueous suspension on experimentally induced gastric ulcers and basal gastric secretion in rats to rationalize its use by herbal and Unani medicine practitioners.Materials and MethodsThe study was conducted at the Medicinal, Aromatic and Poisonous Plants Research Center, College of Pharmacy, King Saud University, Riyadh, Saudi Arabia. Acute gastric ulceration was produced by various noxious chemicals (80% ethanol, 0.2 M NaOH, 25% NaCl and indomethacin) in Wistar albino rats. Anti-secretory studies were undertaken in a separate group of rats. Gastric wall mucus contents and non-protein sulfhydryl concentration were estimated, and gastric tissue was examined histopathologically.ResultsAn aqueous suspension of Black seed significantly prevented gastric ulcer formation induced by necrotizing agents. It also significantly ameliorated the ulcer severity and basal gastric acid secretion in pylorus-ligated Shay rats. Moreover, the suspension significantly replenished the ethanol-induced depleted gastric wall mucus content levels and gastric mucosal non-protein sulfhydryl concentration. The anti-ulcer effect was further confirmed histopathologically.ConclusionThese findings validate the use of Black seed in gastropathies induced by necrotizing agents. The anti-ulcer effect of NS is possibly prostaglandin-mediated and/or through its antioxidant and anti-secretory activities.

The Role of Planar Chromatography in Medicinal Plant Research

This paper summarizes the role of planar chromatography (PC) in medicinal and aromatic plant (MAP) research and development, and demonstrates the importance of the technique, after extraction, in the analysis of MAP (identification and quantitative determination of the separated compound/s), in the purification and isolation process, and in different types of screening procedure. Special attention is paid to analytical, micropreparative and preparative forced-flow techniques, for example overpressured-layer chromatography (OPLC) and rotation planar chromatography (RPC). The special features of analytical, micropreparative, and preparative layer chromatography (PLC), OPLC, and RPC are compared in tables. Purification and isolation procedures using forced-flow techniques are shown in flowcharts. Some applications, relating to different classes of substance, are presented to demonstrate the versatility of various planar chromatographic techniques.
