Extraction of Saponins from Soapnut (Sapindus Mukorossi) and Their Antimicrobial Properties

In this study optimization of extraction conditions for saponin from Sapindus mukorossi was investigated. Results showed that polarity of the extraction solvent affects the yield percentage of the extraction process. Best yield percentage was obtained as 78.1 % at 1:10 solid-liquid ratio in aqueous ethanol solution (50% v/v). The antimicrobial properties of extracts containing saponins were investigated for different microorganisms. Minimum inhibition concentrations of extract were obtained against Escherichia coli, Staphylococcus aureus and Candida albicans. Minimum inhibition concentrations (MIC) of saponin extract ranged between 12.5 mg/mL to 25 mg/mL.nbs

Electroencapsulation (Electrospraying & Electrospinning) of Active Compounds for Food Applications

###EgeUn###With new consumption trends and mindset of a healthier way of life, there is an increasing demand for functional foods. To provide stable and functional products to consumers, the stability of the active compounds must be preserved during the processing of food. For this purpose, encapsulation techniques have been used in various industries in order to overcome problems such as stability, low solubility, and degradation under process conditions for food applications. Electrospinning and electrospraying are two highly versatile and scalable electrohydrodynamic methods, which have gained increasing attention in the various encapsulation applications. This review will give readers an overview of the latest electroencapsulation (electrospraying and electrospinning) of natural bioactive compounds for functional foods applications.COST (European Cooperation in Science and Technology)European Cooperation in Science and Technology (COST) [NutRedOx-CA16112]This article/publication is based upon work from COST Action NutRedOx-CA16112 supported by COST (European Cooperation in Science and Technology)

Antioxidant and Antimicrobial Activities of Extracts from Some Selected Mediterranean Plant Species

In this study, in vitro antioxidant and antimicrobial activities of the plant extracts of four different plant species were evaluated. These plants are Olea europaea (Olive leaf), Liquidambar orientalis (Turkish sweetgum), Ziziphus jujuba (Lotus) and Juniperus communis (Juniper) which are common in Mediterranean region and used in various application, especially for therapeutic purposes. The most efficient extraction yield was obtained for Liquidambar orientalis as 24.7 %, and followed with Ziziphus jujuba and Olea europaea. The extracts of Liquidambar orientalis exhibited the highest phenol content as 0.372 mgGAEq/g sample. Antioxidant activities of the extracts ranged between 8.009 and 0.527 TEAC (mmol/g sample). Extracts of Liquidambar orientalis had the highest antioxidant capacity with 8.009 TEAC (mmol/g sample). The antimicrobial activities of plant extracts were evaluated by using both disc diffusion and minimum inhibition concentration assays. Disc diffusion results were obtained for each plant extracts. The diameter of inhibition zones ranged between 20.5 and 7.8 mm. The extracts of Liquidambar orientalis had the highest inhibition activity with 20.5 and 19.2 mm inhibition zones against Pseudomonas aeruginosa and Escherichia coli respectively. The extract of Olea europaea had second highest antimicrobial activity against E.coli with a inhibition zone diameter of 13.6 mm. Both extracts of Ziziphus jujuba and Juniperus communis showed approximately the same inhibition activity. The minimum inhibition concentration (MIC) values of plant extracts ranged between 0.4 and 100 mg/ml. Liquidambar orientalis extract had the lowest MIC values against Staphylococcus aureus and Staphylococcus epidermidis, Bacillus subtilis. The extract of Juniperus communis had second highest antimicrobial activity against S.epidermidis, S.aureus and B.subtilis with minimum inhibition concentration value of 3.125 mg/ml. nbs
