Sophora comprises 45-50 species of worldwide distribution, but no general proposal as to the evolution of this group has been put forth. We used cladistic relationships of the quinolizidine alkaloids (matrine, sparteine, methylcytisine, anagyrine, and sophoranol) with morphological and palynological characters to suggest a hypothesis of evolutionary and biogeographic relationships. The mainland...

Knema (Myristicaceae family) is a large genus, comprising over 100 species found in of South East Asian countries, among that 10 was Vietnam. pachycarpa native tree distributed central provinces Viet Nam. Until now, only few chemical studies Nam have been reported. Phytochemical study leaves led to the isolation seven known compounds including six flavonoids 5,7,3′-trihydroxy-5′-methoxy isoflav...

BACKGROUND Ku Dou Zi is the dried whole plant, roots and seeds of Sophora alopecuroides L. in the genus Sophora of family Leguminosae. The entire plant is bitter in taste, cold in nature, and has the heat clearing, detoxifying, pathogenic wind dispelling dampness, analgesic, and insecticidal effects. Modern pharmacological studies have proved that TASA has pharmacological activities of anti-can...

BACKGROUND Sophora flavescens Ait. is a traditional Chinese medicine with a long history in China. It is mainly used in the treatment of heat dysentery and similar ailments in the clinical. The objective of this paper was to isolate, purify and identify alkaloids from Sophora flavescens Ait. and to explore their inhibitory effects on C6 glioma cells. MATERIALS AND METHODS Column chromatograph...

Different endophytes isolated from the seeds of Sophora flavescens were tested for their ability to produce matrine production. Response surface methodology (RSM) was applied to optimize the medium components for the endophytic fungus. Results indicated that endophyte Aspergillus terreus had the ability to produce matrine. The single factor tests demonstrated that potato starch was the best car...

in order to study the weeds frequency and dry matter in corn and cowpea sole cropping and intercropping systems, an experiment using replacement and additive techniques was conducted using different combination of intercropping in seven levels with ratio of 1:1 (50% corn + 50% cowpea), 1:2 (33% + 67%), 2:1 (67% + 33%), (100% + 20%), (100% + 10%), 100% corn and 100% cowpea, two levels optimal an...

The present study demonstrated the use of the Linear Quantitative Profiling Method (LQPM) to evaluate the quality of Alkaloids of Sophora flavescens (ASF) based on chromatographic fingerprints in an accurate, economical and fast way. Both linear qualitative and quantitative similarities were calculated in order to monitor the consistency of the samples. The results indicate that the linear qual...
