rhododendron ovatum/抗酸化物質

BACKGROUND Rhododendron brachycarpum (RB) is a genus of flowering plants generally used for traditional medicine in Korea to treat hypertension, neuralgia, and sterility. Previous studies have shown that RB extract alleviate inflammation and antimicrobial activity. OBJECTIVE In this study, the

Rhododendron, one of the most famous ornamental plants in the world, is traditionally a medicinal plant. However, the potential bioactivities of native Rhododendron in Taiwan have not been completely studied. In this study, the results revealed that Rhododendron pseudochrysanthum exhibited the best

In the present investigation, the ultrasound-assisted extraction (UAE) conditions and optimization of Rhododendron arboreum polysaccharide (RAP) yield were studied by a Box-Behnken response surface design and the evaluation of its antioxidant potential. Three parameters that affect the productivity

BACKGROUND Some of the genus Rhododendron was used in traditional medicine for arthritis, acute and chronic bronchitis, asthma, pain, inflammation, rheumatism, hypertension and metabolic diseases and many species of the genus Rhododendron contain a large number of phenolic compounds and antioxidant

The antioxidant activity of extracts obtained from different parts of Georgian flora species Hamamelis virginiana L., Astragalus caucasicus Pall., Astragalus microcephalus Willd., Vitis vinifera L., Rhododendron ponticum L., Rhododendron Ungernii Trautv., Ginkgo biloba L., Salvia officinalis L.,

In the current investigation, we studied role of Rhododendron leaf extract in Vigna radiata grown under chromium metal stress. We observed that seed treatment with Rhododendron leaf extract resulted in the recuperation of seedling growth under chromium toxicity. Seed treatment

In this study, we aimed to optimize the extraction of polysaccharides from the leaves of Rhododendron aganniphum and investigate its rheological properties and antioxidant activity. After optimizing the operating parameters using a Box-Behnken design (BBD), the results showed that the optimal

Antioxidant flavonoids have been isolated from the flower of Rhododendron yedoense var. poukhanense. One new flavonoid and three known flavonoids, quercetin-5-O-beta-D-glucopyranoside (1), quercetin (3), and quercitrin (4), were isolated from the butanol and ethyl acetate extracts of the plant. The

Ethnobotanical evidences report the use of Rhododendron luteum Sweet (Ericaceae) in traditional medicinal systems. However, R. luteum has been associated to the occurrence of 'mad honey' poisoning. In the present study, the ethyl acetate, methanol, and water extracts of R. luteum were investigated

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

Evaluation of native plant resources and their efficient use is one of the current trends in phytochemistry. The main aim of the present study was to investigate the biological activities of different Rhododendron luteum Sweet leaf extracts obtained with the use of accelerated solvent

Rhododendron formosanum is an endemic species distributed in the central mountains of Taiwan. In this study, the biological activities of major procyanidins isolated from the leaf extract of R. formosanum were investigated. Four compounds, including two procyanidin dimers, procyanidin A1 (1) and B3

Rhododendron molle G. Don is an important traditional Chinese medicinal plant, which has been applied to treat some inflammatory diseases. In the present study, ethanol extracts of R. molle flower (RFE) and leaf (RLE) were used for phytochemical, antioxidant and anti-inflammatory analysis. The

In the current investigation, the active principles of the methanol extracts of Rhododendron arboreum leaves (MEL) and flowers (MEF) were investigated with the help of ultra-high performance liquid chromatography (UHPLC), amino acid analyzer and gas chromatography mass spectrometry (GC-MS).

This study investigated some physico-chemical and biochemical characteristics of different honey types belonging to Turkish flora. Sixty-two honey samples were examined on the basis of pollen analyses, including 11 unifloral honeys (chestnut, heather, chaste tree, rhododendron, common eryngo,
