Methylated flavonols form a special group with modulating biological activities in comparison with kaempferol and quercetin. The present study isolated ten compounds including two kaempferol methyl ethers: 5-hydroxy-3,7,4'-trimethoxyflavone (1), 3-hydroxy-5,7,4'-trimethoxyflavone (6);

The antioxidant activity, cytotoxicity and mechanism of induction of HepG2 cell death of essential oil from Amomum tsao-ko were determined. The essential oil was cytotoxic to HepG2, Hela, Bel-7402, SGC-7901 and PC-3 cell lines. The lowest IC(50) of 31.80+/-1.18microg/ml was measured for HepG2

BACKGROUND Medicinal herb-derived drug development has become important in the relief of liver pathology. Amomun cardamomum is traditionally used therapeutically in Korea to treat various human ailments including dyspepsia, hiccupping, and vomiting. We investigated to assess the protective effect of

A simple, green and efficient extraction method named modified-solvent free microwave extraction (M-SFME) was employed for the extraction of essential oils (EOs) from Amomun tsao-ko. The process of M-SFME was optimized with the prominent preponderance of such higher extraction yield (1.13%) than

Chemical composition, in vitro antioxidant, DNA damage protective, nitrite scavenging activities, as well as antibacterial activity of Amomum kravanh fruits essential oil against several foodborne pathogens, were investigated. Results showed that the 1,8-cineole (58.53%) was found as the main

Our previous study showed that tsao-ko intake can lower plasma and liver triacylglycerol (TG) concentrations and has hypoglycemic and antioxidant activity in mice. This study involved separating two major fractions (A and B) from the methanol extracts (MeX) of tsao-ko using silica gel column

In order to gain insight into the antioxidant effect of cinnamon (Cinnamomum verum; Lauraceae) and cardamom (Amomum subulatum; Zingiberaceae) hepatic and cardiac antioxidant enzymes, glutathione (GSH) content and lipid conjugated dienes were studied in rats fed high fat diet along with cinnamon or

OBJECTIVE Amomum xanthoides is a well-known traditional herbal medicine mainly for diverse digestive system disorders in Asia for a long time. In the present study, we investigate the effects and action mechanism of methanol fraction of Amomum xanthoides (MFAX) on thioacetamide (TAA)-induced liver

Lipids extracted from tsao-ko were separated into three fractions with silica gel column chromatography and fed to mice (3 mo old) for 90 d to clarify their inhibitory activity on digestive enzyme activity. The diets contained the following: control--no tsao-ko, 0.05% total lipid of tsao-ko (TL),

Amomum villosum Lour. (Zingeraceae) is a perennial herb that occurs in the understory of tropical and subtropical forests, and is an important medicinal plant. A. villosum, native to Guangdong province, was introduced intentionally to Xishuangbanna, Yunnan province in 1963, and was planted under

The aim of this study was to investigate the chemical composition and bioactivity of Amomum biflorum Jack harvested in the region of Petchaboon, Thailand. The essential oil of the fresh whole plant obtained by hydrodistillation was analyzed by gas chromatography (GC) (Kovats index) and gas

BACKGROUND Amomum xanthioides Wall. ex Baker (Zingiberaceae) is a tropical medicinal plant that is commonly utilized in the treatment of digestive system disorders in Asia for a long time. OBJECTIVE This study aimed to evaluate the hepatoprotective effect and related mechanisms of A.

Despite its deleterious effects on living cells, oxidative stress plays essential roles in normal physiological processes and provides signaling molecules for cell growth, differentiation, and inflammation. Macrophages are equipped with antioxidant mechanisms to cope with intracellular ROS produced

In the present study, the extraction, purification, characterization and biological activities of polysaccharides from the seeds of Amomum villosum (ASP) were investigated. Firstly, the optimal parameters for the extraction of ASP were obtained by using a Box-Behnken Design as follows: extraction

Amomum nilgiricum is one of the plant species reported from Western Ghats of India, belonging to the family Zingiberaceae, with ethno-botanical values, and is well-known for their ethno medicinal applications. In the present investigation, ethyl acetate and methanol extracts of A. nilgiricum were
