Phytochemical characteristics and antioxidant activities of the crude and fractionated plant extracts of Anoectochilus formosanus were evaluated using five different assay systems. An acid-treatment (2 N HCl in 95% ethanol) was employed to treat a butanol fraction (BuOH), creating an acid-hydrolyzed
Anoectochilus formosanus Hay. and Gynostemma pentaphyllum Makino are popular folk medicines that have been used for treating hepatitis, hypertension and cancer in Taiwan. Our previous studies showed that these crude drugs exert antiinflammatory activity and hepatoprotective activity against
Radical-scavenging activity of isorhamnetin (1) and its diglycosides, named isorhamnetin-3,5'-O-β-D-diglucoside (2) and isorhamnetin-3,7-O-β-D-diglucoside (3) extracted from Anoectochilus roxburghii, has been studied through three main
This study evaluated a novel use of the traditional Asian herb Anoectochilus formosanus. This plant is a traditional food item, generally used for the treatment of liver disorder, hepatitis, hypertension, diabetes, cardiovascular disorder, etc. In this study, the root, stem, and leaf of A.
1. In the present study, we investigated aqueous extracts of Anoectochilus formosanus (AFE) for antihyperglycaemic and anti-oxidant effects in diabetic rats induced by streptozotocin (STZ). 2. Diabetic rats were randomly divided into groups and treated orally by gavage with vehicle (distilled water)
The hypoglycemic and antioxidant effects of the water extract from Anoectochilus roxburghii in alloxan-induced diabetic mice were examined. Compared with untreated diabetic mice, the daily oral administration of the water extract from A. roxburghii at 0.5 or 2 g/kg for 14 days caused a significant
The physicochemical properties (molecular weights and monosaccharide compositions), antioxidant and hepatoprotective activities of polysaccharides (ARPPs: ARPP30, ARPP60 and ARPP80) isolated from Anoectochilus roxburghii were investigated. ARPP80 exhibited relatively strong antioxidant activities in
This study used MAE and RSM to extract phenolic compounds from Anoectochilus roxburghii, and the optimum conditions defined by the model to give an optimum yield of 1.31%. The antioxidant activity in vitro showed when the concentration of phenolic compounds was reached 1 mg mL-1, the clearance rates
Anoectochilus formosanus (AF) is a popular folk medicine in Taiwan whose pharmacological effects have been characterized. In this work we investigated the antioxidant properties of an aqueous extract prepared from AF. The AF extract was capable of scavenging H2O2 in a dose-dependent manner. We
Anoectochilus roxburghii, a famous Chinese herbal medicine, has been commonly used for the treatment of liver disease, diabetes, and rheumatoid arthritis. Our study aimed to investigate the anti-rheumatoid arthritis effects of A. roxburghii polysaccharides (ARP), using the rat's model of type II
This study investigated biological activities including antioxidative stress, anti-inflammation, and anti-insulin resistance of Anoectochilus burmannicus aqueous extract (ABE). The results showed abilities of ABE to scavenging DPPH and ABTS free radicals in a dose-dependent manner. Besides, ABE
Anoectochilus roxburghii, a traditional Chinese medicinal herb, has been widely used for treating numerous chronic diseases. In this study, a polysaccharide from A. roxburghii (ARPs-p) was purified by anion exchange and size exclusion chromatography. The structural characteristics of ARPs-p were
The aim of this study was to investigate the effects of light quality on the morphological traits, leaf anatomical characteristics, antioxidant enzyme (superoxide dismutase, catalase, and peroxidase) activities, photosynthetic pigments content, and bioactive compounds (phenols, flavonoids, and
BACKGROUND
Anoectochilus roxburghii (Wall.) Lindl. is traditionally used for the treatment of various types of chronic and acute hepatitis in China. Considering that Anoectochilus roxburghii polysaccharide (ARPT) is the main constituent of Anoectochilus roxburghii, the present study was designed to
This study investigated the isolation and characterization of Anoectochilus roxburghii polysaccharides (ARP), and further evaluated whether ARP possessed hepatoprotective activities against CCl4-induced oxidative liver damage in mice. ARP is comprised of glucose and galactose in a 1.9:1 molar ratio,
