Black soybeans contain high antioxidant compounds such as isoflavone but mainly in glucoside form, with low activities. Fermentation by lactic acid bacteria (LAB) can enhance the properties, its ability is strain-dependent. This study aims to of Indonesian indigenous LAB, Lactiplantibacillus plantarum WGK 4, Streptococcus thermophilus Dad 11, and 13, properties during black soy milk fermentatio...

Osmotic drying of celery leaves was studied in two osmotic solutions (ternary aqueous solution and sugar beet molasses), at three temperatures (20, 35, 50?C), diverse immersion periods (1, 3, 5 hours). The aim to examine the influence used hypertonic agent, temperature time on antioxidant capacity (AOC) color characteristics samples. AOC assessed by spectrophotometric assays (ABTS, FRAP, DPPH),...

The antioxidant properties from medicinal plants have protective effects against oxidative stress-linked diseases. Their antioxidantcapacities are related to phenolic compounds, including phenols and flavonoids.Clinacanthus nutans, a native Asia, includingMalaysia, Thailand, Indonesia, used for treating diabetes other diseases, but the exploration of plant in Indonesia isstill limited. Therefor...

In this study, we have examined the antioxidant activity and total phenolic content of different extracts (including water, methanol, water : methanol and acetone) of Nerium oleander L. grown in the north of Iran by employing various in-vitro assay, i.e. DPPH free radical scavenging, reducing power and total antioxidant capacity through the Mo (VI) reduction. The extracts showed different level...

Algae and seaweeds are used in cookery since the beginnings of human civilization, particularly several Asian cultures. Phenolic compounds secondary metabolites produced by aquatic terrestrial plants for their natural defense against external stimuli, which possess powerful antimicrobial antioxidant properties that can be very important food industry. The main objective this study was to develo...

In this study, the methanolic extracts from four medicinal plants (Sarcopoterium spinosum, Paronychia argentea, Inula viscosa, and Achillea fragrantissima) were tested in vitro for antibacterial antioxidant properties. The properties of these MPEs assessed using disc diffusion Serial dilution techniques. evaluated by DPPH FRAP methods. total phenolic compounds measured according to Folin-Ciocal...

Sodium bicarbonate is sometimes used to aid in the extraction of total polyphenols. Its main effect increase pH solution. Raising can cause changes chemical structure This lead variations their biological properties, solubility and stability. work studied sodium carbonate on by aqueous decoction polyphenols from leaves Combretum micranthum. The content phenolic compounds extracts was estimated ...

Lysimachia nummularia L. is a perennial herbaceous plant rich in bioactive compounds, which can be utilized for medicinal purposes. The present work aims to analyze the phenolic compounds from different parts of using HPLC technique: Lysimachiae radix (the root part), herba aerial flores (flowers). In order determine extraction three categories vegetable products was performed with ethanol 70% ...

Background: Avocado is a plant that can grow in tropical climates. In general, people only consume the fruit while skin and seeds are not used. fruit, contain secondary metabolites such as flavonoids tannins which have antioxidant activity. Objective: To determine activity, total flavonoid, tannin content of ethanol extract avocado peel. Methods: P. americana Mill. was collected from Lubuk Ling...

Propolis, arıların bitkilerin çeşitli kısımlarından topladığı reçine benzeri doğal bir maddedir. Arılar propolisi patojenlere karşı koruyucu olarak kullanırlar. Propolis zengin içeriği sayesinde birçok biyolojik etkiye sahiptir. Perga, yavrularını beslemek için kullandığı polen ve baldan oluşan fermente üründür. Bu çalışmanın amacı fenolik bileşiklerce olan perganın, antimikrobiyal aktivitesini...
