BACKGROUND Extraction temperature influences the total phenolic content (TPC), total flavonoid content (TFC) of medicinal plant extracts to a great extend. TPC and TFC are the principle activity constituents present in the plant. The effects of extraction temperature on TPC, TFC and free

BACKGROUND Diabetes mellitus is a serious disease affecting about 5% of people worldwide. Although several studies have indicated hypoglycemic activities of Gynura divaricata (GD), the mechanisms by which GD improves the symptoms of diabetes remain unclear. OBJECTIVE The aim of this study was to

Gynura bicolor (Compositae) which is widely used by the locals as natural remedies in folk medicine has limited scientific studies to ensure its efficacy and nontoxicity. The current study reports the total phenolic content, antioxidant capacity, cytotoxicity, and acute oral toxicity of crude

Gynura procumbens (Lour.) Merr. is an evergreen edible vine in southern China. The antioxidant activity and metabolites of chlorogenic acid dimer from Gynura procumbens (Lour.) Merr. were evaluated by the model of in vitro digestion and in vivo metabolomics approach, respectively. Moreover,

Gynura segetum, family Compositae, is a cultivated species and can be found growing in the tropical regions of Indonesia and Malaysia. The plant is known for its use for the treatment of cancer, inflammation, diabetes, hypertension and skin afflictions. In the current study, in vivo

Gynura procumbens and Cleome gynandra are two herbs commonly used in Malaysia to treat various ailments and are also consumed as salads (ulam) and vegetables. The present study aims to evaluate the relationship between the chemical compositions of both herbs and their antioxidant and

BACKGROUND Ethanolic extract of G. procumbens leaves has been previously shown to possess antihyperlipidemic effects. OBJECTIVE This study was designed to prepare caffeoylquinic acids rich and poor fractions of the ethanolic extract using resin column technology and compare their antihyperlipidemic

Gynura formosana Kitam (family Compositae) has traditionally been used for the prevention of diabetes, cancer and inflammation in China. However, there are few reports of its anti-inflammatory effects. In the present study, after assessing the in vitro antioxidant activities of extracts from Gynura

BACKGROUND The phytochemical composition of aqueous and ethanol extracts from Gynura bicolor DC., a vegetable, was determined. Human umbilical vein endothelial (HUVE) cells were used to examine the antioxidative and anti-inflammatory potentials of these extracts at 1, 2 or 4% (v/v) against

It is well known that plants can grow under space conditions, however, perturbations of many biological phenomena have been highlighted due to the effect of altered gravity and its possible interaction with other factors (e.g., CO2 , ion radiation, etc. Our aim was to test whether elevated CO2 could

The present study investigates the antioxidant activity of 28 wild edible plants (WEPs) resources of Loktak Lake wetland ecosystem of Manipur, North East Indian Himalayan Region and their correlation with phenolics and flavonoids. Antioxidant activity was measured by DPPH, ABTS and FRAP assay. The

A randomized complete block (RCBD) study was designed to investigate the effects of cadmium (Cd) and copper (Cu) on the growth, bioaccumulation of the two heavy metals, metabolite content and antibacterial activities in Gyanura procumbens (Lour.) Merr. Nine treatments including (1) control (no Cd

Medicinal plants are important source of drugs with pharmacological activities. Therefore, there is always rising demands to discover more therapeutic agents from various species. Orthosiphon stamineus, Gynura procumbens and Ficus deltoidea are

Gynura procumbens (Lour.) Merr. is traditionally used as a raw material for making dumplings or steamed stuffed buns, and its fresh leaves are boiled with water for tea. Herein, we established an ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry

OBJECTIVE In order to assess traditional Thai claims about the therapeutic potential of medicinal plants and to select plants for future phytochemical research, nine plant species with anti-inflammatory uses were selected from Thai textbooks and assessed for their in vitro anti-inflammatory,
