Bioreduction of silver nanoparticles (AgNPs) from silver ions (Ag) using water extract of Thai basil leaf was successfully carried out. The basil leaf extract provided a reducing agent and stabilizing agent for a synthesis of metal nanoparticles. Silver nanoparticles received from cut and uncut basil leaf was compared. The resulting silver nanoparticles are characterized by UV-Vis spectroscopy....

The aim of this study was to estimate the genetic divergence between African cowpea lines from the Cowpea Germplasm Bank of Embrapa Meio-Norte, Brazil. The morphoagronomic diversity of 57 cowpea lines was assessed using multivariate analysis. The germplasm was evaluated in August 2009 using a randomized block design with three replications based on the following traits: number of pods per pedun...

Rice is the most important durable food product for more than half of world’s population, as it very nutritious in terms carbohydrate containment and can meet a large part human caloric needs on daily basis. The sensitivity rice fortified with spearmint or basil was evaluated three stored insect species: Sitophilus oryzae (L.) (Coleoptera: Curculionidae), Rhyzopertha dominica (F.) Bostrychidae)...

Since the 1980s cowpea has become an alternative cash crop in northern Senegal. However, in 1997, surveys showed that farmers often sold their crop at unprofi table prices. The hypothesis was that farmers could improve selling prices if they produced cowpea with the characteristics demanded by consumers. To identify those characteristics, data were collected in six markets from January 1998 to ...

Background: Groundnut bud necrosis virus (GBNV) (Tospovirus genus, Bunyaviridae family) infects the major crops of solanaceae, leguminosae and cucurbitaceae in India. Temperature is an important factor which influences the plant growth and development under diseased conditions.Objective: In the present study, we evaluated the effect of four different temp...

This study aims to determine the effect of substitution tofu flour and corn by addition sodium bicarbonate in a completely randomized design with two replicates. The first factor is flour: (S) are: S1=100:0, S2=25:75, S3=50:50, S4=75:25, S5=0:100. second adding (P), which consists three levels, namely: P1=0.00 %, P2=0.20 P3=0.30 %. observed parameters: protein content, water fat ash organolepti...

Abstract This study aimed to determine the best concentration of sago liquid sugar obtain quality cookies. used a completely randomized design (RAL) with five treatments and three replications, namely: P0 (100% granulated cane 0% starch sugar), P1 (75% 25% P2 (50% 50% P3 (25% 75% P4 (0% 100% sugar). Data were statistically analyzed using ANOVA DNMRT at 5% level. The results showed that ratio si...

Of 17 spices and herbs tested at 1% (wt/vol) in Mueller-Hinton (MH) agar, only cloves, thyme, oregano, allspice, basil, rosemary, and marjoram showed antimicrobial effects on Shigella. The MICs of thyme, oregano, basil, and rosemary (as determined by the agar dilution method) ranged from 0.5 to 1% (wt/vol) depending on the Shigella strain used. With the use of various combinations of temperatur...

Effects of four tropical plant (Aframomum melegueta, Zanthoxylum zanthoxyloides, Piper guineense and Eugenia aromatica) were investigated under tropical laboratory storage conditions for the protection of cowpea seeds against insect infestation. The plant materials were pulverised into fine powder after air drying and admixed with 20 g of cowpea seeds at the ...

OBJECTIVES Various antibacterial and antiplaque agents are used in chemical plaque control but none are without their shortcomings. Chlorhexidine considered a gold standard, also has an array of side effects. To overcome these, numerous herbal extracts have been tried and tested and one among them is holy basil. The present study evaluated the antibacterial efficacy of holy basil in vitro again...
