Since ancient times, honey has been appreciated not only for its sensorial traits, but also the observed effects in rejuvenation and treatment against several bad health conditions, when used externally or internally, along with other beehive products, such as pollen, propolis royal jelly. Today, it is known that are generated by compounds bearing antimicrobial, anti-inflammatory, antioxidative...

BACKGROUND Rhododendron anthopogonoides Maxim, a kind of traditional Tibetan medicine, has been used to remove body heat, body detoxification, cough, asthma, stomachic and swelling, eliminate abundant phlegm and inflammatory for a long time. In the present study, the total phenols and total flavonoid contents as well as antioxidative properties of the crude extract and solvent fractions of R. a...

recently, subcritical water extraction (swe) has been well known as a green technology for extraction of bioactive compounds from plants. in this study, subcritical water extraction, ultrasound assisted extraction (uae) and shaker solvent extraction (sse) were compared for extraction of phenolic compounds from fig (ficuscarica) pulp and skin. antioxidant activity of the extracts was evaluated u...

a peer-reviewed, open access online international journal which publishes original research papers. The welcomes submission from scholars and experts for possible publication all over the world. scope of includes: Pharmaceutical research, chemistry biochemistry naturally occurring compounds, biological evaluation crude extracts, ethnomedicine, traditional complementary medicine, ethnopharmacolo...

The aim of this study was to identify the flavonoid constituents of the Bulgarian endemic Alchemilla jumrukczalica Pawl. and evaluate the antiradical scavenging activity of the total extract, fractions and individual compounds. The total MeOH extract exhibited a significant DPPH activity (IC50 10.7±0.4 μg/ml), while EtOAc fraction obtained after partition of the total extract was found to be th...

Grape pomace is a potential source of natural antioxidant and antimicrobial agents. Phenolic compounds, antioxidant, and antibacterial properties of pomace extracts from four Virginia-grown grape varieties were investigated. White grape pomaces had higher (P < 0.05) solvent extraction yield than red varieties. Concentrations of total phenolic (TPC), total flavonoid (TFC), total anthocyanin (TAC...

background: the use of natural products as anticancer and antioxidant agents has a long history. several drugs currently used in chemotherapy were isolated from plant species. objective: the aim of this study was to evaluate cytotoxicity and antioxidant activity as well as phenol and flavonoid contents of five plant species of solanaceae family. methods: five plant species of solanaceae family ...

Seasonal discrepancy in the antioxidant potential from bark of Nothapodytes nimmoniana was evaluated using two different methods (DPPH and FRAP) and were related to total phenolic content as well as flavonoid content. Higher yield of phenolic and flavonoid were observed during summer (May) similarly, the antioxidant activities (DPPH & FRAP) also were high. The antioxidant activities were strong...

The polyphenol content and antioxidant activity of Nonpareil, Carmel, Butte, Sonora, Fritz, Mission, and Monterey almond cultivars harvested over three seasons in California were examined. LC-MS was employed to quantify 16 flavonoids and two phenolic acids in acidified methanol extracts of almond skins. The 3-year mean polyphenol content of cultivars ranged from 4.0 to 10.7 mg/100 g almonds. Is...
