In this study, the antibacterial activity of ethanol and methanol extracts of Zataria multiflora and Teucrium polium was determined against Paenibacillus alvei by disc diffusion method. Paenibacillus alvei is one secondary bacterium for the European foulbrood disease in honey bee. Minimum inhibitory concentration and minimum bactericidal concentration were determined by using the serial dilution method. For this, Z. multiflora and T. polium are collected from different areas of Iran then they are dried and extracted in lab. The antibacterial effect of alcoholic extracts of Z. multiflora and T. polium was lower than usual standard antibiotics (P<0.01), but the ethanol and methanol extracts of Z. multiflora at a concentration of 60mg/ml, have inhibitory and lethal effects on P. alvei. Also, 100mg/ml concentrations of ethanol extract of T. polium has inhibitory and lethal effects on this bacterium. But, the no one of used concentrations of its methanol extract has inhibitory and lethal effects. Results indicated that used extracts of Z. multiflora have the higher antibacterial effects than extract of T. polium on Paenibacillus alvei. It can be concluded that regarding the high antibacterial power of Z. multiflora, it is necessity to work on how they can be used in control and treatment of bacterial honey bee diseases.

A series of derivatives of trans-3-(2,4,6-trimethoxyphenyl)4,5-dihydroisoxazolo-4,5-bis[carbonyl-(4′phenyl)thiosemicarbazide (9) and of trans-3-(2,4,6-trimethoxyphenyl)-4,5-dihydro isoxazolo-4,5-bis(aroylcarbohydrazide) (10a–c) were synthesized from trans-3-(2,4,6-trimethoxyphenyl)-4,5-dihydro-4,5-bis(hydrazenocarbonyl)isoxazole (8). The structures of the compounds were elucidated by both elemental and spectral (IR, NMR, and MS) analysis. Compound 9 shows activity against some bacterial species. No antibacterial activities were observed for compounds 10a–c. The antioxidant activity of the new compounds has been screened. Compound 9 showed higher antioxidant activity using the DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2’-azino–bis(3-ethylbenzoline-6-sulfonic acid) diammonium salt methods.

Tetrapleura Tetraptera

The use of antioxidants has emerged as a promising therapeutic strategy for the management of mitochondrial dysfunction and other oxidative stress-related degenerative pathologies. Tetrapleura tetraptera is a well-known tree and its fruit is applied traditionally as spice and in the preparation of remedies for different ailments. In this study, the gas chromatography-mass spectrometry (GC-MS) analysis and mitochondrial functionality potential of T. tetraptera fruits were investigated. GC-MS was used to detect compounds in then-hexane and ethanol extracts of T. tetraptera fruits. Cupric reducing antioxidant capacity (CUPRAC) assay was used to evaluate the mitochondrial functionality potential of the ethanol extract. GC-MS analysis revealed the presence of six compounds in then-hexane extract of T. tetraptera fruits. These compounds were detected in trace quantities, the most abundant being 2,3-dimethyl-3-buten-2-ol (0.04%). The compounds: cis-vaccenic acid (35.37%), n-hexadecanoic acid (28.09%), 6-octadecenoic acid (25.21%), and octadecanoic acid (11.33%) were identified in the ethanol extract of the fruits. Consequently, the ethanol extract was subjected to CUPRAC assay. The ethanol extract exhibited a concentration-dependent high cupric reducing capacity, returning CUPRAC values in the range of 0.090 to 0.403 at the concentration of 10 – 80 μg/ml. This activity was comparable to that of the positive control, naringenin, which showed CUPRAC values of 0.059 – 0.378 at the same concentrations. These results indicate that T. tetraptera fruits possess good antioxidant property as evaluated by other related antioxidant assays. This could be attributed to a synergistic effect of the phytochemical constituents. Hence consumption of T. tetraptera fruits could be beneficial for the prevention of mitochondrial dysfunction and other oxidative stress-related degenerative disorders.
