The Cosmos bipinnatus has been used in a traditional herbal remedy for various diseases such as jaundice, intermittent fever, and splenomegaly. The present study describes the preliminary evaluation of antioxidant activities and antigenotoxic effect of Cosmos bipinnatus flowers according to four

Influence of growth stage and season on the antioxidant constituents of Cosmos caudatus.

Only registered users can translate articles

The impact of tropical seasons (dry and wet) and growth stages (8, 10 and 12 weeks) of Cosmos caudatus on the antioxidant activity (AA), total phenolic content (TPC) as well as the level of bioactive compounds were evaluated using high performance liquid chromatography (HPLC). The plant morphology

Flavonoid content and antioxidant activity of vegetables from Indonesia.

Only registered users can translate articles

Extracts from 11 vegetables of Indonesian origin were screened for flavonoid content, total phenolics, and antioxidant activity. The flavonols myricetin, quercetin, and kaempferol and flavones luteolin and apigenin were quantified by HPLC. Flavonoid content in mg/100 g fresh weight (fw) was

The effects of Cosmos caudatus (Ulam Raja) supplementation on bone biochemical parameters in ovariectomized rats.

Only registered users can translate articles

Cosmos caudatus (ulam raja) contains high mineral content and possesses high antioxidant activity which may be beneficial in bone disorder such as postmenopausal osteoporosis. The effects of C. caudatus on bone metabolism biomarkers in ovariectomized rats were studied. 48 Sprague-Dawley rats aged

Cosmos caudatus as a potential source of polyphenolic compounds: optimisation of oven drying conditions and characterisation of its functional properties.

Only registered users can translate articles

The aim of the study was to analyze the influence of oven thermal processing of Cosmos caudatus on the total polyphenolic content (TPC) and antioxidant capacity (DPPH) of two different solvent extracts (80% methanol, and 80% ethanol). Sonication was used to extract bioactive compounds from this

Highlights

Cosmos caudatus Ethanolic extract fractionation by n-butanol produced a phenolics-saponin rich fraction.Cosmos caudatus butanol fraction was the most potent in all antioxidant and MTT assays.High concentrations of all fractions increased cells migration

The presence of zinc reduced cadmium uptake and translocation in Cosmos bipinnatus seedlings under cadmium/zinc combined stress.

Only registered users can translate articles

Cadmium (Cd) and zinc (Zn) coexist in the environment but interact differently in plants. Cosmos bipinnatus has been potentially considered as a Cd-accumulator. Thus, this study investigated the detoxification mechanism in C. bipinnatus seedlings under Cd, Zn and Cd + Zn stresses. In the present

Osteoporosis is considered a serious debilitating disease. Cosmos caudatus (ulam raja), a plant containing antioxidant compounds and minerals, may be used to treat and prevent osteoporosis. This study determines the effectiveness of C. caudatus as bone protective agent in postmenopausal osteoporosis

Protective effects of total flavonoids of Bidens bipinnata L. against carbon tetrachloride-induced liver fibrosis in rats.

Only registered users can translate articles

Bidens bipinnata L. is well known in China as a traditional Chinese medicine and has been used to treat hepatitis in clinics for many years. In a previous study we found that total flavonoids of Bidens bipinnata L. (TFB) had a protective effect against carbon tetrachloride (CCl4)-induced acute liver

Enrichment of flavonoid-rich extract from Bidens bipinnata L. by macroporous resin using response surface methodology, UHPLC-Q-TOF MS/MS-assisted characterization and comprehensive evaluation of its bioactivities by analytical hierarchy process

Only registered users can translate articles

The extract of Bidens bipinnata L. exhibited wide spectrum of bioactivities due to the presence of flavonoids. In this study, the purification process was developed to enrich the flavonoids-rich extract from B. bipinnata L. (BBTF). AB-8 resin was selected for the purification of total flavonoids.
