In this study, callus and cell suspension were induced from seedlings of licorice (G. uralensis). In addition, it was revealed that the appropriate concentration of sucrose could promote the callus growth and increase the content of polysaccharide. The methyl jasmonate (MJ) and phenylalanine (PHE) could enhance the callus growth and content of flavonoids(More)
Formosanin C (FC) isolated from Rhizoma Paridis, showed pro-apoptosis and immunoregulation with antitumor activity in cultured cells and animal systems. However, there is no report about its anti-metastatic effect on cancer cells. This research used the wound healing and the migration assay to detect the anti-invasive effect of FC on LA795 cells. Through(More)
Saponins are a group of naturally occurring plant glycosides, characterized by their strong foam-forming properties in aqueous solution. The presence of saponins has been reported in more than 100 families of plants out of which at least 150 kinds of natural saponins have been found to possess significant anti-cancer properties. There are more than 11(More)
ETHNOPHARMACOLOGICAL RELEVANCE Cytotoxicity and hemolysis of saponins were the characteristic activities. Many researches have been devoted to the synthesis of saponins devoid of the hemolysis by structure-activity relationship studies. However, saponins contained in the plants were not fully researched on the two activities such as Parissteroidal saponins.(More)
Rhizoma paridis saponins (RPS) played a good antitumor role in many clinical applications. However, low oral bioavailability limited its application. In this research, water extract of Curcuma (CW) significantly increased antitumor effect of Rhizoma paridis saponins (RPS). GC-MS was used to identify its polar composition. HPLC was applied for determination(More)
We investigated the influence of ammonia/nitrate ratio and phosphate concentration on biomass and accumulation of metabolites in adventitious roots of Glycyrrhiza uralensis Fisch. A NH4 +/NO3 − ratio of 10:20 was optimal for the production of biomass (0.30 g dry weight) as well as polysaccharide (18.98 mg g−1) and glycyrrhetinic acid (0.31 mg g−1). The(More)
Formosanin C (FC) is a pure compound isolated from Rhizoma Paridis. In the past years, antitumor effects of FC have been observed in several cultural cells and animal systems. However, there was no research particular on liver cancer. In this experiment, 3-(4, 5-dimethylthiazol diphenyltetrazolium bromide (MTT) dye reduction assay was used to evaluate cell(More)
ETHNOPHARMACOLOGICAL RELEVANCE Paris polyphylla var. yunnanensis as a traditional Chinese medicine has been used in the treatment of liver disease for thousands of years. Rhizoma paridis saponins (RPS), as the main active components of Paris polyphylla, have been used to treat liver injury. Anti-cirrhosis effect of Rhizoma paridis saponins (RPS) has not(More)
Rhizoma Paridis saponins are bioactive steroidal saponins derived from Paris polyphylla. Optimization of the ionization process was performed with electrospray ionization tandem mass spectrometry in both positive and negative-ion modes. Negative-ion ESI was adopted for generation of the precursor deprotonated molecules to achieve the best ionization(More)
Rhizoma Paridis Saponins (RPS), which is the effective part of Rhizoma Paridis, showed strong anti-lung cancer and anti-hepatocarcinoma activities. In this research, a gas chromatography/mass spectrometry (GC/MS) method was developed and validated for the metabolic profiling of RPS intervention in H22 hepatocarcinoma mice. Data were analyzed with partial(More)
