In helical strips of dog mesenteric, coronary and cerebral arteries and mesenteric veins contracted with prostaglandin F2 alpha, sophoramine (10(-4) and 10(-3) M) produced a concentration-related relaxation, which was not influenced by treatment with indomethacin, atropine, aminophylline,
The effects of sophoramine on experimental arrhythmias in animals and its mechanisms were studied. Sopaoramine is an alkaloid isolated from Sophora alopecuroides L. The iv and ip LD50 of sophoramine in mice were found to be 74.90 +/- 17.86 and 106.15 +/- 1.05 mg/kg respectively. Sophoramine showed
OBJECTIVE
Evaluation of the Sophora alopecuroides var. alopecuroides seed effects on morphine withdrawal syndrome in mice and determination of the alkaloid composition of the seed total extract.
METHODS
The effects of the seed total extract, alkaloid fraction and major compound matrine on the mice
OBJECTIVE
To study the chemical constituents of the alkaloid fraction of Kushen decoction.
METHODS
Constituents were isolated by different kinds of column chromatography and their structures were elucidated with spectral methods.
RESULTS
Eight compounds were isolated and identified as matrine (I),
A rapid method for the determination of quinolizidine alkaloids by nonaqueous capillary electrophoresis was developed. A total of 10 alkaloids (matrine, sophocarpine, oxymatrine, oxysophocarpine, sophoridine, cytisine, sophoramine, aloperine, lehmannine and dauricine) could be easily separated
Manipulating insect behavior through the deployment of semiochemicals offers a promising opportunity for protecting crops in a sustainable manner. Therefore, there is still a significant opportunity for the development of natural crop protectants as eco-friendly tools in pest management. In this
A new matrine-type alkaloid, 7alpha-hydroxysophoramine (1), was isolated from the aerial parts of Sophora alopecuroides together with eight known alkaloids, 12beta-hydroxysophocarpine (2), sophoramine (3), 14beta-hydroxymatrine, matrine, sophoridine, sophocarpine, adenocarpine, and baptifoline. The
A new matrine-type alkaloid, 7α-hydroxysophoramine (1), was isolated from the aerial parts of Sophora alopecuroides together with eight known alkaloids, 12β-hydroxysophocarpine (2), sophoramine (3), 14β-hydroxymatrine, matrine, sophoridine, sophocarpine, adenocarpine, and baptifoline. The structures
A new cytisine-type alkaloid, along with five known alkaloids was obtained from the seeds of Sophora alopecuroides. Their structures were determined to be (-)-N-(2'-hydroxy-3',5'-di-tert-butyl-toluene)-cytisine (1), (-)-lupanine (2), (+)-matrine (3), (+)-sophoramine
Previous studies have demonstrated that the total alkaloids of Sophora alopecuroides (TASA), which contains many different ingredients like sophocarpine, matrine, oxymatrine, sophoridine, sophoramine, aloperine and cytosine, were able to protect colon against ulcers caused by 2,4,6-trinitrobenze
To study the chemical constituents in the bark of Sophora japonica.
The chemical constituents were separated and purified by silica gel,Sephadex LH-20 column chromatography,and HPLC. Their structures were identified by various spectroscopic analyses.
Eleven compounds were obtained from the bark of
Herbal medicines were one of the major resources for healthcare in earlier stages, and some traditional herbal medicines have been in use for more than 2000 years. Currently, they are attracting more and more attention of the modern pharmaceutical industry, as scientists has become aware that herbs
Quinolizidine alkaloids are the main bioactive components in Sophora alopecuroides L. This study reports a novel ultrasound-assisted enzymatic hydrolysis method for the extraction of these important alkaloids. Box-Behnken design, a widely used response surface methodology, was used to investigate
The seeds of Sophora alopecuroides L. var. alopecuroides (S. alopecuroides) have alleviated morphine withdrawal in mice. Therefore, in this study, the alkaloid composition of S. alopecuroides extract was determined by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) analysis.
Three new matrine-type alkaloids, (+)-5α-hydroxyoxysophocarpine (1), (-)-12β-hydroxyoxysophocarpine (2), and (+)-5α-hydroxylemannine (3), along with 14 known analogues, (-)-sophocarpine (4), (-)-5α-hydroxysophocarpine (5), (-)-9α-hydroxysophocarpine (6), (+)-12α-hydroxysophocarpine (7),
