The use of colorants in the dried noodle manufactures is an effort of product diversification. Besides of being used as a natural coloring agent, this peel extract is also used to improve nutritional value of the expected product. The purpose of this study was to determine the effect of red dragon fruit peel extract on the physical quality of dried noodle.  The study was conducted by using Completely Randomized Design (CRD) method with one factor, namely concentration of red dragon fruit peel extract (N1 = 10 ml, N2 = 15 ml, N3 = 20 ml, N4 = 25 ml, N5 = 30 ml).  The observations of its physical quality consisted of water absorption, solid loss during cooking, and organoleptic tests (aroma and color).  The best quality of dried noodle was obtained by using 30 ml red dragon fruit peel extract (N5) with physical properties, namely DSA levels of 351.92%, solid loss during cooking 4.78%, aroma 3.79 (like) and color 3.89 (like).

Edible film and coatings are been looked upon for preservation of fruits, vegetables and bakery products. Extended shelf life with preservation of natural properties of food is always been a challenge; by incorporation of bio-actives in edible coatings, the shelf life can be increased as they are known for their antioxidant and antimicrobial properties. With this view, present study was undertaken, where edible coatings were prepared from starch, gelatin and glycerol and incorporated with Lemon peel extracts and coated on apples for increased shelf life. Antimicrobial activity of Lemon peel extracts was studied on eight organisms by broth dilution method and were found to be effective at concentration 3mg/mL-9mg/mL for bacteria and 50mg/mL- 90mg/mL for fungi. Fuji apples coated with starch-gelatin based edible formulation containing lemon peel extracts were studied for the effect of coating on fruit shelf life during storage for 28 days. Incorporation of lemon peel extract into edible coating improved shelf life with reducing rate of browning of apples.

Teratogenic is an abnormal development on embryo and is the cause of congenital defect or birth defect. This study aims to determine the effect of the addition of Dioscorea alata L. ethanol extracts to the embryo development on pregnant mice whose given orally to 24 mice which divided to 4 treatment groups, they are the normal group (NG) with NaCMC 0.5%; 28 mg/KgBB treatment group; 35 mg/KgBB; 42 mg/Kg BB. The addition of Dioscorea alata L ethanol extracts was done on the sixth day until the 15th day of pregnancy. On the 18th day of pregnancy, Laparaktomi was done to the pregnant mice and the embryo was taken out of the uterus. The observation was done to the fetus numbers, weight weighing of the fetus's body, dan length measurement of the fetus's body. Another observation is the observation of the external organ defect of the embryo. The study results that the addition of Dioscorea alata L ethanol extracts with various doses have no significant effect (P>0.5) to the mice external fetus development. On the examination of the fetus, we can conclude that Dioscorea alata L ethanol extracts don’t give any effect that may cause the defect of the fetus’ external organ.

Multiple sclerosis is a chronic inflammatory and demyelinating disorder of the central nervous system (CNS) that can cause cognition, mobility, and sensory impairments. Studies have shown that the immune system through inflammation and autoreactive T cells are involved in the progression of MS. The present article aimed to review the potent anti-inflammatory, antioxidant, and immunomodulatory agents that could modulate the immune response in MS. In herbal medicine, various medicinal plants including Olive, Silybum marianum, Grape, Pomegranate peel extract, Nigella sativa, Turmeric, Green tea, Aloysia citrodora, Boswellia papyrifera, Boswellia serrata, Ruta graveolens, and Andrographis paniculata are known with therapeutic benefits in MS patients through immunoregulation and reduction of major symptoms.

Background: Funcionalized multi-walled carbon nanotubes (ox-MWCNTs) were used for the preparation of therapeutic nanoparticles for delivery of some bioactive compounds. Consequently, this work deals with the preparation of grafted MWCNTs with n-vinyl caprolactam in the presence of pomegranate peel extract (P. granatum), titanium dioxide (TiO2) and/or silver nanoparticeles and their toxic effects on male mice using in vivo biological examination (liver and kidney dysfunction biomarkers) and the histopathological analysis. Methods: P. granatum extract was immobilized onto functionalized MWCNTs using simple adsorption technique. Moreover, The prepared materials were analyzed by Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM). In vivo examination using liver and kidney dysfunction biomarkers was investigated. In addition, the histopathological study was carried out. Results: The ox-MWCNTs induced significant elevation in the liver enzymes including AST, ALT and ALP relative to the control group. While, the treatment with P. granatum extract only did not induce any change in the liver and kidney biomarkers. In other words, P. granatum extract loaded onto functionalized MWCNTs showed low effects on liver enzymes and kidney function biomarkers in the treated mice in comparison with ox-MWCNTs and extract separately. Moreover, histopathological analysis revealed that the P. granatum extract functionalized MWCNTs exhibited normal renal tissue with no histopathological alteration. Conclusion: The grafted MWCNTs with n-vinyl caprolactam in the presence of pomegranate peel extract (P. granatum), titanium dioxide (TiO2) and/or silver nanoparticeles were successfully prepared. SEM-micrographs showed complete coating of MWCNTs fiber with the extract. The prepared materials resulted in no toxic effects and the histopathological findings were confirmed by inflammation of the liver and kidney tissues.

Background: Fungal infections are opportunistic infections that become a serious problem to human health. Objective: Considering the antifungal potential of triazole nucleus, the study was carried out with the objective to synthesize some novel triazole derivatives with antifungal potential. Method: 1,2,4-triazole derivatives were synthesized via a two step reaction (reported earlier). The first step involves reaction of substituted benzoic acid with thiocarbohydrazide to form 4-amino-3-(substituted phenyl)-5-mercapto-1, 2, 4-triazole derivatives (1a-1k) while in second step, synthesized compounds (1a-1k) were then subsequently treated with substituted acetophenone to yield substituted (4-methoxyphenyl-7H-[1, 2, 4] triazolo [3, 4-b][1,3,4] thiadiazine derivatives (2a-2k). All synthesized compounds were characterized by IR, 1H NMR, and Mass spectral data analysis and were screened for their antifungal properties against different fungal strains i.e. Candida tropicalis (ATCC-13803, ATCC-20913), Candida albicans (ATCC-60193), Candida inconspicua (ATCC-16783) and Candida glabrata (ATCC-90030, ATCC-2001). Results: Compound 2d displayed better percentage inhibition (26.29%, 24.81%) than fluconazole (24.44%, 22.96%) against ATCC-16783, ATCC-2001 fungal strains respectively at 100µg/ml. Compound 2f also displayed better percentage inhibition (28.51%) against ATCC-90030 as compared to fluconazone (27.4%) at 200 µg/ml. Similarly, compounds 2e and 2j also exhibited better antifungal properties than fluconazole at 200µg/ml. Compound 2e was found most potent against ATCC13803 (30.37%) and ATCC-90030 (30.37%) fungal strains as compared to fluconazole (28.14%, 27.4%) at 200 µg/ml respectively whereas compound 2j exhibited better antifungal activity (28.51%) against ATCC-60193 than fluconazole (27.7%) at 200 µg/ml. Conclusion: The results were in accordance with our assertions for triazole derivatives, as all compounds displayed moderate to good antifungal activity.
