Herbal teas was are widely consumed by people around the world have high antioxidant activities. The flavor and color combination of specific enriches aroma appearance tea, producing a tea with fresh tastier flavor. This study determines activity telang flower (Clitoria ternatea), pineapple (Ananas comosus), formula called TeNan. activities herbal were measured 2,2 Diphenyl-1-picrylhydrazyl (DP...

Purpose: To evaluate protein hydrolysates and membrane ultrafiltration fractions of blue-spotted stingray for metal chelating and radical scavenging activities, as well as protection against oxidative protein damage. Methods: Stingray protein isolates were hydrolysed with alcalase, papain and trypsin for 3 h. Alcalase hydrolysate was fractionated by membrane ultrafiltration to yield < 3, 3 10 a...

The fruit of Averrhoa carambola L. (A. L.) belongs to the Oxalidaceae family, is probably native Ceylon and Moluccas, commonly known in various places as “star-fruit” or “carambola.” This used traditional medicine for a variety diseases. phenolic compounds that contains are thought be responsible its many benefits. Currently there extensive research on content antioxidant capacity A. Most autho...

To explore the antioxidant potential of hen egg white lysozyme N-acetylmuramide Glycan hydrolase in full fat Mozzarella cheese, an experiment was conducted where control sample brined without addition lysozyme; while four samples were along with 0.02%;w/v (T1), 0.04%;w/v (T2), 0.06%;w/v (T3) and 0.08%;w/v (T4) lysozyme. The cheese measured through several methods, including 2, 2-azino-bis (3-et...

Antioxidant capacity (AOC) against peroxyl radical and 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt (ABTS) radical cation was measured for a series of p-hydroxybenzoic (HB) and p-hydroxycinnamic (HC) acids at different pH. Quantum-chemical computation was performed using Gaussian 3.0 software package to calculate the geometry and energy parameters of the same compoun...

The antimelanogenic and antioxidant activities of the essential oil extracted from the leaves of Acorus macrospadiceus (Yamamoto) F. N. Wei et Y. K. Li have never been explored. The essential oil effectively inhibited mushroom tyrosinase activity (EC(50) = 1.57 mg/mL) and B16F10 tyrosinase activity (IC(50) = 1.01 mg/mL), decreased the melanin content (EC(50) = 1.04 mg/mL), and depleted the cell...

Considerations on antioxidants derived from plants have continuously increased during this decade because of their beneficial effects on human health. In the present study we investigated the free radical scavenging properties of extracts from Piper guineense (P. guineense) and their inhibitory potentials against oxidative mediated ion toxicity. The free radical quenching properties of the extr...

BACKGROUND Medicinal and aromatic plants play a significant role in drug discovery and development process. Flavonoids, revealing a wide spectrum of biological activities, extensively found in plants are important secondary metabolites. MATERIALS AND METHODS Aerial parts of Cyclotrichium origanifolium were collected, dried, and boiled in water then extracted with hexane, ethyl acetate, and n-...

BACKGROUND Laccases are multi-copper oxidases that catalyze the one electron oxidation of a broad range of compounds. Laccase substrates include substituted phenols, arylamines and aromatic thiols. Such compounds are activated by the enzyme to the corresponding radicals. Owing to their broad substrate range laccases are considered to be versatile biocatalysts which are capable of oxidizing natu...
