atractylenolide ii/atractylodes

Ionizing radiation (IR) can act as a negative factor for human homeostasis, by causing and even aggravating a series of pathological conditions. To protect the intactness of normal tissues, effective anti-radiation drugs are urgently needed for alleviating the outcomes of radioactive damage. In this

Atractylenolide II (AII) and atractylenolide III (AIII) are the major active components in Atractylodes Macrocephala Rhizoma (AMR). In this study, a sensitive, rapid and selective liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for the simultaneous

The biotransformation of atractylenolide II, a major bioactive principle of the rhizomes of Atractylodes macrocephala Koidz., was investigated in vitro by incubation with rat hepatic microsomes pretreated with sodium phenobarbital. The biotransformation products were extracted and purified by

BACKGROUND Atractylenolide II (AT-II) is a sesquiterpene compound isolated from the dried rhizome of Atractylodes macrocephala (Baizhu in Chinese), which is traditionally prescribed for melanoma treatment by Chinese medicine practitioners. Our previous study showed that AT-II can inhibit B16 cells

Atractylenolide II (AT-II) exhibits several biological and pharmacological functions, especially anti-cancer activity as the major sesquiterpene lactones isolated from Atractylodes macrocephala (also named Baizhu in Chinese). However, the effects and mechanisms of AT-II on human gastric cancer

In the studies of chemoprevention, the Nrf2-ARE signaling pathway has received widespread attention due to its anti-inflammatory and anti-oxidation effects. Our previous study indicated that atractylenolide II, which is an active component of Atractylodes macrocephala Koidz, is a potential activator

Atractylodis Rhizoma is the dried rhizome of Atractylodes lancea (Thunb.) DC. or Atractylodes chinensis (DC.) Koidz and is often processed by stir-frying with wheat bran to reduce its dryness and increase its spleen tonifying activity. However, the mechanism by which the processing has

OBJECTIVE To research the process mechanism of Atractylodes macrocephala and conversion of sesquiterpenes from it. METHODS The contents of atractylenolide I, II and III in the different processed herbal medicines were determined by HPLC. The conversion of the sesquiterpenes was proved by the

The rhizomes of Atractylodes macrocephala are used as both a food source and traditional Chinese medicine in China. A phytochemical investigation was carried out on wild A. macrocephala grown in Qimen County in eastern China, and yielded a novel bisesquiterpenoid lactone, namely, biatractylenolide

The rhizome of Atractylodes ovata De Candolle is rich in essential oils, which are usually removed by processing. In this study, anti-oxidative abilities of essential oils and aqueous extracts of A. ovata rhizome were explored, and the influence of processing on the anti-oxidative abilities was

Bai-Zhu, the dried rhizome of Atractylodes macrocephala Koidz (AMK), is widely used as a tonic herbal in eastern Asia. It is commonly used as prepared slices in clinic by stir-frying with wheat bran (processed AMK). In the theories of traditional Chinese medicine (TCM), Bai-Zhu possesses

In the present study, two new compounds, together with six known compounds, were isolated from rhizome of Atractylodes macrocephala Koidz by a series of silica gel, ODS column chromatography, and preparative HPLC. Their structures were characterized as atractylenolide II (1), atractylenolide I (2),

The rhizome of Atractylodes ovata (Bai Zhu in Chinese) is a widely used traditional Chinese herb in Taiwan as a tonic agent. In this paper, four sesquiterpenoids, namely atractylon, and atractylenolides I, II, and III, were isolated from the n-hexane extract of A. ovata and were evaluated for

OBJECTIVE The rhizome of Atractylodes ovata De Candolle is popularly used in traditional Chinese medicine to treat gastrointestinal diseases. However, the major gastroprotective compounds of A. ovata have not been identified. This study reports on the principal gastro- protective component of A.

Several Chinese herbal medicines (CHMs) are used in the treatment of insomnia, restlessness, or anxiety. However, mechanisms underlying this effect and scientific proof for their traditional use is scarce. In the present study CHMs were screened for their ability to modulate GABA-induced chloride
