A rapid and accurate strategy of screening, identification, and purification of antioxidants from natural medicines was put forward in this work, and it was applied to discover the antioxidants from magnolia officinals Rahd. et Wils. On-line HPLC-DPPH combined with electrospray ionization
This study demonstrated that the aqueous extracts of plants employed in Mexican traditional medicine for the treatment of cardiovascular diseases are able to modify the tone of arterial smooth muscle. Agastache mexicana (Kunth) Lint & Epling (Labiatae), Chenopodium murale L. (Chenopodiaceae),
Microwave-assisted extraction was employed to extract polyphenols from the leaf of Magnolia kwangsiensis Figlar & Noot.. The polyphenols yield was 2.44±0.02% under the optimal conditions of RSM: acetone concentration of 70%, ratio of solvent to material of 21 mL·g -1 and extraction time of 16 min.
.This study aimed to investigate the hypolipidemic and antioxidant activities of volatile oils from Michelia martini Levl. The antioxidant property of volatile oils from Michelia martini in vitro was investigated by establishment of various systems. High fat diet induced rats were used to assess the
We reported the discovery of potent antioxidants based on magnolol, a naturally occurring biphenolic obtained from the bark of Magnolia officinalis. The allylmagnolols 3a,b were synthesized via O-alkylation of the biphenols followed by Claisen rearrangement. In-vitro using enhanced chemiluminescence
Acute liver failure (ALF), an often fatal condition characterized by massive hepatocyte necrosis, is frequently caused by drug poisoning, particularly with acetaminophen (N-acetyl-p-aminophenol/APAP). Hepatocyte necrosis is consecutive to glutathione (GSH) depletion and mitochondrial damage caused
BACKGROUND
Restenosis is a common complication after balloon angioplasty. A number of cytokines, chemotactic factors and growth factors may be involved. Several antioxidants have been shown to inhibit intimal thickening after balloon injury in hyperlipidemic animals.
OBJECTIVE
The effects of
The antioxidative effect of more than 50 ethanol extracts of Chinese drugs were studied on the air oxidation of linoleic acid. Several ethanol extracts such as Glycyrrhiza uralensis, Magnolia officinalis and Zingiber officinale etc., were found having stronger antioxidative effect.
Six different cultivars of banana flowers (Musa paradicicus) (Kathali, Bichi, Shingapuri, Kacha, Champa, and Kalabou) were analyzed for the content of polyphenol expressed as gallic acid equivalent and flavonoid expressed as quercetein equivalent, and the in vitro total antioxidative activities of
Magnolia grandiflora (Magnoliaceae) is an evergreen tree with fragrant and showy flowers native to southeastern USA but widely cultivated all over the world and used in cosmetics industry in treatment of skin diseases. Here, we report on the chemical analysis of the essential oil obtained from
BACKGROUND
Magnolia grandiflora L. flower is wildly used in Asian as a traditional herbal medication. The purpose of the study was to investigate the antimelanogenic and antioxidant properties of Magnolia grandiflora L. flower extract. In the study, the inhibitory effects of M. grandiflora L. flower
Tree bark represents an important source of medicinal compounds that may be useful for cancer therapy. In the current study, high-performance liquid chromatography with diode-array detection (HPLC-DAD) was used to determine the profile of the phenolic compounds of Catalpa speciosa, Taxus
Gwakhyangjeonggi‑san (GHJGS) is a mixture of herbal plants, including Agastache rugosa, Perilla frutescens, Angelica dahurica, Areca catechu, Poria cocos, Magnolia officinalis, Atractylodes macrocephala, Citrus reticulata, Pinellia ternata, Platycodon grandiflorum, Glycyrrhiza uralensis, Ziziphus
In this study, the effects of magnolia (Magnolia (M.) denudata) extract fermentation in increasing the extract's antioxidative and anticancer activities were investigated. Magnolia was fermented by Pediococcus acidilactici KCCM 11614. The total phenolic content was determined by the
This study intended to improve physiological characteristics of Magnolia officinalis bark (MOB) extracts by Aspergillus niger fermentation. M. officinalis bark was extracted using distilled water, 95% ethanol, and methanol, and it was then fermented by A. niger. The
