AIM OF THE STUDY Depression is a severe mood disorder. It was treated with Shudihuang, the steamed roots of Rehmannia glutinota Libosch. (SRG), in traditional Chinese medicine. The present paper was designed to verify its antidepressant effect. MATERIALS AND METHODS A mouse model of depression was established though unpredictable chronic mild stress(More)
OBJECTIVE To establish a method for the germplasm preservation of R. glutinosa. METHOD Plantlets of different cultivars obtained by tip culture were inoculated into test tubes with MS medium supplemented with 0.2 mg.L-1 BA and 0.02 mg.L-1 NAA, and preserved at 4-6 degrees C in dark. At the same time, different media (A. distilled water + 10 g.L-1 agar; B.(More)
OBJECTIVE In the Chinese Pharmacopoeia (2010 edition), the minimum limit of verbascoside (acteoside) in Rehmanniae Radix Praeparata (RRP) was set at 0.20%, the rationality of the standard was evaluated in this paper. METHODS 10 samples of Rehmanniae Radix (RR) and RRP were collected or prepared. According to the traditional method, different samples of(More)
ETHNOPHARMACOLOGICAL RELEVANCE Intestinal mucositis induced by chemotherapy is a severe clinical problem in cancer patients that currently lack effective interventions. In traditional Chinese medicine, chemotherapeutic toxicity is diagnosed as Qi and Yin deficiency, and steamed rehmannia root (SRR) is frequently prescribed to these patients. Whether SRR can(More)
OBJECTIVE To evaluate the germplasm of Rehmannia glutinosa on the basis of photosynthetic pigment contents (PPC). METHOD 20 cultivars were planted on the same condition. On Oct. 23 and Sept. 25, 3 leaves per cultivar were collected on different plants, and 80 mg mesophyll was collected among upper lateral veins and was ground in 96% alcohol, and the(More)
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a major public health problem and gives arise to severe chronic morbidity and mortality in the world. Inflammatory response and oxidative stress play dominant roles in the pathological mechanism of COPD, and have been regarded to be two important targets for the COPD therapy. Traditional Chinese(More)
OBJECTIVE To optimize the processing of mannatriose preparation from stachyose by acidolysis. METHODS An orthogonal experiment was performed to select a better condition of acidolysis. Fructoes and stachyose was determined by HPLC. RESULTS Among the factors set in the present work, temperature and time have little influence on the acidolysis, while the(More)
BACKGROUND The dried and steamed roots of Rehmannia glutinosa have different pharmacological functions and indications. Catalpol, the main active component of the dried root, was found to be entirely degraded together with amino acids and some oligosaccharides during preparation of the steamed root. Its degradation may contribute to the differences between(More)
The progress in the studies on chemical constituents and pharmacological activity of the genus Pfaffia is summarized in recent 20 years. These plants contain various chemical constituents and have broad bioactivities such as sthenic, anti-tumor, analgesic and anti-inflammatory and should be further investigated.
