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 Alkaloids of Sophora alopecuroides have good biological activity, and are widely used in clinical settings, which not only have pharmacological activities of anti-cancer, cancer suppression, as well as the inhibition, and killing of various microorganisms; but also possess extensive pharmacological effects on immune system, nervous system and cardiovascular system. The objective of t...

Th e aerial parts and seeds of Sophora alopecuroides L. var. alopecuroides growing in Turkey were investigated for their alkaloid compositions and antimicrobial activities. Th e alkaloid extracts were analysed by capillary gas chromatography-mass spectrometry (GC-MS). Th e main components were identifi ed as sophoridine (33.07%), matrine (24.03%), and sophocarpine (8.01%) in the aerial parts, a...

Sophora alopecuroides lectin (SAL), a novel lectin from the seeds of Sophora alopecuroides, was purified by ion-exchange chromatography on diethylaminoethyl (DEAE)- and carboxymethyl (CM)-Sepharose columns, followed by gel filtration on a Sephadex 75 10/300 GL column. SAL was found to be a monomer of 39916.3 Da, as determined by tricine-sodium dodecyl sulphate-polyacrylamide gel electrophoresis...

Endophytes MQ23 and MQ23R isolated from Sophora alopecuroides root nodules were characterized by observing their ability to promote plant growth and employing molecular analysis techniques. Results showed that MQ23 and MQ23R are potential N2-fixing endophytes and belong to the same species as Bacillus cereus. MQ23 was shown to be able to produce siderophores, IAA, and demonstrate certain antifu...
