Objective: To analyze the phytochemical constituents, and to explore potential protective effect of the methanol extract of moringa oleifera(m. oleifera) seeds and Egyptian propolis, each alone or concurrently administered on acetic acid-induced ulcerative colitis in rats. methods: Eight groups of 5 rats each were used: normal control group with distilled water, model group, two groups with m. oleifera seeds(100 and 200 mg/kg), two groups with propolis(50 and 100 mg/kg), one group with concurrent administration of both, and one group with prednisolone(reference drug). macro-and microscopic picture, ulcer index and lesion scores, oxidative markers, inflammatory mediators, in vitro activity of the inflammatory enzymes and 1, 1-diphenyl-2-picrylhydrazyl free radicals scavenging activity were evaluated. The phytochemical constituents of both extracts were explored by GC-mS analysis. Results: Both treatments modulated the macro-and microscopic picture, decreased the ulcerative index, lesion score, oxidative markers and inflammatory mediators, and inhibited the COX-1 and COX-2 enzymes. Propolis appeared to be powerful free radicals scavenger. A powerful synergistic effect of both treatments in modulating the course of the disease was reported. GCmS analysis of methanol extract of m. oleifera seeds and propolis revealed the presence of 50 and 34 compounds, respectively. Conclusions: m. oleifera seeds and propolis methanol extracts have modulated the course of acetic acid-induced ulcerative colitis. moreover, both treatments induce a good synergistic effect against the disease. Isolation of the active constituents is recommended.

Objective: To evaluate the potential antioxidant and hepatoprotective effects of n-hexane, dichloromethane(DCm), ethyl acetate(EtOAc), n-butanol and aqueous fractions of moringa oleifera(m. oleifera) leaves methanol extract against carbon tetrachloride(CCl_4)-induced liver injury in rats. methods: These fractions were prepared from the m. oleifera leaves methanol extract by solubilization in water and partitioning in n-hexane, EtOAc, DCm and n-butanol. Their phyto-components were identified by GC-mS analysis. The in vitro antioxidant effect of these fractions was carried out by assessment of 1,1-diphenyl-2-picrylhydrazyl scavenging activity. A total of 40 Sprague Dawley rats were allocated into 8 equal groups: group 1 given olive oil(1 m L/kg ***.), group 2 injected with CCl_4, group 3 to 7 administered with n-hexane, DCm, EtOAc, n-butanol and aqueous fractions, respectively after CCl_4, group 8 administered with silymarin after CCl_4. The activities of aspartate aminotransferase, alanine aminotransferase, and the levels of total cholesterol, triglycerides, glucose, total proteins and albumin in serum were determined spectrophotometrically. Glutathione reduced, lipid peroxide by-products levels, glutathione-s-transferase and catalase enzyme activities in the liver homogenate were determined by spectrophotometer. Liver specimens were also examined for histopathological alterations under light microscope. Results: The GCmS analysis of different fractions of the m. oleifera leaves methanol extract revealed that n-hexane, DCm, EtOAc, n-butanol, and aqueous fractions contained 17, 22, 23, 19 and 32 compounds, respectively. The percent and the molecular structure of each component in each fraction were identified. The n-butanol and EtOAc fractions exhibited the strongest in vitro antioxidant activity against 1,1-diphenyl-2-picrylhydrazyl.

Journal of Ocean University of China 2018年第5期17卷 1178-1188页

作者： mOHY EL-DIN soad m. mOHYELDIN mohamed m. Botany and microbiology Department Faculty of ScienceAlexandria UniversityAlexandria 21511Egypt Pharmacognosy Department Faculty of PharmacyAlexandria UniversityAlexandria 21521Egypt

The polar and nonpolar extracts of Colpomenia sinuosa, Padina pavonia, Cystoseira barbata and Sargassum vulgare collected during spring, summer and autumn were evaluated for their antifungal activities. The phytochemicals of unexplored seaweeds were analyzed by gas chromatography and mass spectrometric （GC/mS）. The algal extracts were tested for their antifungal activities against Aspergillus niger, A. flavus, Penicillium parasiticus, Candida utilis and Fusarium solani. Phytochemicals were extracted from the four seaweeds with various solvents including methanol, ethanol, acetone, chloroform and dimethyl ether. Among the various extracts, methanolic extract showed the highest inhibition activity on all fungal species. Seasonal variation in antifungal activity was studied, while methanol extracts showed the best antifungal activity in spring. Cystoseira barbata was the most effective seaweed, having anatifungal activity throughout the whole year. The UV-Vis phytochemical procedure and GC-mS analysis of the methanol extracts from tested species indicated the existence of different constituents. In conclusions, the compounds with antifungal activity were identified as indoles, terpenes, acetogenins, phenols, and volatile halogenated hydrocarbons.

Four rhizobacteria selected out of over 500 isolates from rhizosphere of the vegetables in China were further studied for suppression of the root-knot nematode and soil-borne fungal pathogens in laboratory and greenhouse in Belgium. They were identified as Brevibacillus brevis or Bacillus subtilis by Biolog test and partial 16s rDNA sequence comparison. They not only inhibited the radial growth of the root-infecting fungi Rhizoctonia solani SX-6, Pythium aphanidermatum ZJP-1 and Fusarium oxysporum ***. cucumerinum ZJF-2 in vitro, but also exhibited strong nematicidal activity by killing the second stage larvae of meloidogyne javanica to varying degrees in the greenhouse. The toxic principles of bacterium B7 that showed the highest juvenile mortality were partially characterized. The active factors were heat stability and resistance to extreme pH values. B7 used either as seed dressing or soil drench significantly reduced the nematode populations in the rhizosphere and enhanced the growth of mungbean plants over the controls in the presence or absence of R. solani.
