Effect of Natural Source as Stimulator on Vegetative Growth, Flowering, Chemical Composition and Oil on Viola Odorata, Linn.

The purpose of the present work was to evaluate the vegetative growth of Mentha piperita L. cultivated under different water availability, as well its influence in content, chemical composition and in vitro antioxidant activity of its essential oil. Plants were propagated by mother plants microcutting and scions were transplanted to 5 L pots with soil and cattle manure. Afterward, were kept at field capacity for 30 days and under treatment for 40 days. It was treated with different levels of water deficit treatments: (T1): 100 of field capacity (FC); (T2): 80 of FC; (T3): 60 of FC; (T4) 40 of FC with 5 blocks. Vegetative growth was evaluated by dry matter contents of all part of plants and by root/aerial rate. The essential oil of the leaves was extracted by hydrodistillation, analyzed by GC-FID and GC-MS and in vitro antioxidant potential was evaluated. A significant decrease in the dry matter of leaves and stems accompanied with a decrease in the roots dry matter was observed with an increase in the water stress. Quantitative chemical differences were observed in the chemical composition of the essential oil, according water availability. Total antioxidant activity showed a gradual increase as water stress progressed.

This investigation was conducted in a private farm, Samannoud district, El-Gharbia Governorate, Egypt, during two successive seasons of 2017 and 2018 to study the effect of organic fertilizers and foliar spray of amino acid on vegetative growth, fruit yield, chemical composition and capsaicin content of hot pepper (Capsicum annum L var. Minimum) plant. The experiment included 13 treatments obtained from cattle manure at rates of 60 and 30 N-units per fed. combined with amino acid at 0, 100 and 200 ppm as well as chicken fertilizer at rates of 60 and 30 N-units per fed combined with amino acid at 0, 100 and 200 ppm, besides the treatment of NPK at recommended dose as a control. A complete randomized block design with three replicates was adopted. The obtained results showed that, the highest values from vegetative growth parameters, fruit yield, chemicals composition and capsaicin content were obtained from plants treated with cattle manure full dose + 200 ppm amino acids , followed by plants treated with chicken manure full dose + 200 ppm amino acids compared with all treatments except plant height, the highest value was obtained from plants treated with NPK (control) in the two seasons. Amino acid had a great effect when added with organic fertilization, whether cattle manure or chicken fertilizer at a concentration of 100 or 200 ppm. Based on the previous results, it could be recommend that spraying amino acids (glycine and glutamine) at the rate of 200 ppm along with organic fertilizers at the rate of 60 nitrogen units per feddan get the highest fruits yield, Vitamin C and capsaicin of hot pepper.

Background: The exploration of the plant biodiversity as a natural source to obtain sustainable food products and new bioactive pharmaceutical compounds has been growing significantly due to their abundance, safety and economy. Natural pharmaceutical and edible compounds present some advantages when compared to synthetic ones, such as being chemically inert and widely available. In this sense, plants of the genus Pereskia belonging to the Cactaceae family, have been studied. It is an unconventional wild edible plant that contains a large amount of protein and minerals. Studies have demonstrated their biological activities and potential application in different areas such as pharmaceutical, medicinal and food. Objective: This review is focused on the chemical composition, functional properties, applications on pharmaceutical, nutraceutical and food areas and formulation techniques to enhance the stability and bioavailability of bioactive compounds from the underutilized wild edible plant known as ora-pro-nobis (Pereskia aculeata or Pereskia grandifolia). Conclusion: The latest studies involving ora-pro-nobis demonstrated its great potential due to its biological activities, which could stimulate further investigations. The utilization of this plant as a natural source to supplement the diet, or to prepare new food products and pharmaceutical formulations is an attractive approach to explore and fully realize the potential of the rich biodiversity found in Brazil and in other countries.

Aflatoxin B

The aims of the current work are in large part the benefit of rice straw to be used as adsorbent material and natural source of fiber in Fino bread. The rice straw was subjected to high temperature for modification process and the chemical composition was carried out and the native rice straw contained about 41.15% cellulose, 20.46% hemicellulose, and 3.91% lignin while modified rice straw has 42.10, 8.65, and 5.81%, respectively. The alkali number was tested and showed an increase in the alkali consumption due to the modification process. The different concentrations of modified rice straw, aflatoxin B1, and pH were tested for removal of aflatoxin B1from aqueous media and the maximum best removal was at 5% modified rice straw, 5 ng/mL aflatoxin B1, and pH 7. The modified rice straw was added to Fino bread at a level of 5, 10, and 15% and the chemical, rheological, baking quality, staling, and sensory properties were studied. Modified rice straw induced an increase of the shelf life and the produced Fino bread has a better consistency.
