Authors:Safoora Borzoo , Sasan Mohsenzadeh , Danial Kahrizi Pages: 1 - 10 Abstract: Camelina sativa, being a flowering plant in the family Brassicaceae, is traditionally cultivated as an oilseed crop due to its exceptionally high level (up to 45%) of omega-3 fatty acids, which is uncommon in vegetable sources. In the recent years camelina has been growing more than before because of its potentiality in the production of biodiesel and bioproduct. An aforementioned experiment was designed in three irrigation levels (100%, 75% and 50% of field capacity) and Micrococcus yunnanensis was used as plant growth-promoting bacteria during the reproductive phase. The bacteria were incubated in a nutrient broth medium at the temperature of 28°C for 24h on shaker ceaselessly. When sowing, seeds were treated with 1.0 ml bacteria suspension in the inoculated groups. Water stress was applied to each pot in the levels of 75 and 50 % FC from the budding stage to full maturity in generative phase. Camelina silique yield was harvested at the maturity stage for analysis of seed quality and biochemical responses. Total soluble carbohydrate was extracted thrice from 100 mg of mature seed using extraction soluble including glacial acetic acid, methanol, and water. Oil and protein content were measured using Near-Infrared Reflectance spectrometer. Seed fatty acid contents were determined using gas chromatography. The results showed a significant relation between the highest proportion of fatty acid and the polyunsaturated fatty acid (55.12 to 65.66%) in particular linolenic acid. The increase of polyunsaturated fatty acid and saturated fatty acid was coincided with the decrease of monounsaturated fatty acid under water deficit stress. The application of plant growth-promoting bacteria is proven to increase protein with 50% of field capacity. In general, water deficit stress and plant growth-promoting bacteria have significant effects on the remobilization of nutrients from the soil to developing seed and following metabolism synthesis.

Authors:Tao Yuan, Xin-yu Wen , Zhi-qiang Zhang , Yi Huang Pages: 11 - 18 Abstract: Objective: Compared the nuclear magnetic resonance (NMR) fingerprint spectra of Ophiopogon japonicus from three planted regions in Sichuan province and used multiple stoichiometric methods to distinguish these medicinal material's production areas. Methods: The 1H-NMR data of three Ophiopogon japonicus-producing areas in Sichuan province were obtained. Three stoichiometric methods---similarity analysis, clustering analysis, and principal component analysis (PCA) were used to analyze these 1H-NMR characteristics. Results: There were significant differences in Ophiopagon japonicus from the three production areas. Samples in distinct regions of the same large production area could also observe a slight divergence. The similarity analysis, clustering analysis, and PCA analysis results consistently indicated that NMR spectroscopy combined with chemical measurement analysis could identify the production areas of medicinal material. Conclusion: This study established a method of determining the Ophiopogon japonicus's district based on the 1H-NMR fingerprint map and stoichiometric methods. The technique was relatively simple and could serve as a basis for identifying the production areas of Ophiopogon japonicus, providing a reference for developing and utilization of Ophiopogon japonicus.

Authors:Shabnam Kumari Thakur, N. V. L. Suvarchala Reddy V., Ganga Raju M., Poojeetha Sree, Sappa Sowmya , Sree Lakshmi S., Suchitra J. Pages: 19 - 29 Abstract: The current study focuses on the green production of silver nanoparticles utilising an ethanolic extract of Millingtonia hortensis leaves. This medicinal plant was high in the phenol and flavonoids classes of chemicals. They converted silver nitrate into silver nanoparticles (AgNPs), which were then characterised by FT-IR, particle size analysis, and Zeta potential. The FT-IR analysis confirmed the existence of several functional groups around AgNPs. The particle size examination revealed that the synthesised silver nanoparticles were spherical in shape and nano in size. The zeta potential of AgNPs was determined to be -14 mV; this negative value validates particle repulsion and so increases the formulation's stability. The antioxidant and anti-diabetic properties of AgNPs were investigated, and the results revealed significant free radical scavenging ability, inhibition of carbohydrate digesting enzymes (α-Amylase and α-glucosidase). The green synthesized silver nanoparticles were found to be a promising phyto-medicine for the treatment of diabetes.

Authors:Oyeyemi. S. Dele , Raymond O. Pages: 30 - 41 Abstract: Corn silk is an agricultural waste material from corn cultivation. The need for a supplement feed material that would be readily available, affordable and has nutritional qualities prompted this study. Fresh and dry corn silk were collected from a farm land in Ado Ekiti, Ekiti State, Nigeria and evaluated for phytochemical and nutritional composition using standard techniques. The phytochemical analysis revealed that both the young and matured corn silk contained alkaloids, tannins, saponins, flavonoids, phenols, steroids and reducing sugar. The qualitative phytochemical estimates showed high concentration of flavonoids and total phenols while tannins were found in moderate quantities. The proximate estimation (%) revealed high values of carbohydrate and crude fiber, moderate crude protein and ash, low crude fat, low moisture as well as high energy content in young and matured corn silk respectively. Both samples contained high K, P, Ca, Mg, moderate Na, Fe, Mn, Zn and Cu while Pb and Ni, toxic metals, were absent. The results showed low mineral CV% which ranged from 1.32-38.92. The results of the mineral safety index were lower than the standard, an indication that there would be no mineral overload. The two corn silk samples were rich in active secondary metabolites which could offer protective health benefits, also safe and contained nutritional qualities that could make them suitable to be incorporated into man’s diet and domestic feed.
