The amorpha fruticosa spironolone geared up by the tactic has superior item purity, and industrial amplification is a snap to appreciate.
Get amorpha fruticosa leaf,, acquire by weighing 2kg, be a part of supercritical CO as a result of pulverization approach 2In the extractor, as entrainment agent, use is twenty% of a medicinal content weight with ethanol, extracts, and extraction temperature is 50 ℃, and extracting force is 28MPa, CO 2Flow is 3ml/g crude drug/min, and also the extraction time is 4h, and separating even now I temperature is forty ℃, and stress is 10MPa, and separating however II temperature is 35 ℃, and stress is 7MPa, obtains extract, stirs with ETHYLE ACETATE and would make dissolving, filters, and the filtrating concentrate drying gets crude extract; Adopt the Wrong indigo spiral shell ketone during the higher-pace countercurrent chromatography separation and purification crude extract, its two-stage solvent process is petroleum ether-ethyl acetate-methanol-h2o, and quantity ratio is eight:three:seven:three, on to fill Using the substantial pace adverse latest chromatogram post mutually be stationary phase; Rotate principal frame, pump into down and do shifting phase mutually, shifting stage is dissolved crude extract with the sampling valve sample introduction, the UV-detector on-line checking; The detection wavelength is 209nm, collects Wrong indigo spiral shell ketone ingredient, vacuum focus; Individual out crystallization, leach crystallization, insert the dissolving of eighty% methanol eddy; Area recrystallization, filtration, washing are drying to get Bogus indigo spiral shell ketone, information ninety six.two%. Embodiment 4:
Average values of parameters of structural dynamics, compactness and hydrogen bond Investigation of cost-free ITK and also the ITK-ligand units above a hundred ns

Structure and stereochemistry of amorphispironone, a novel cytotoxic spironone sort rotenoid from Amorpha fruticosa
The creation belongs to the standard Chinese medicine extraction separation technologies field, relate to a style of process for planning Fake indigo spiral shell ketone of from amorpha fruticosa Amorphispironone leaf, separating.
Precedence day (The precedence day is definitely an assumption and is not a legal conclusion. Google has not done a authorized Assessment and tends to make no representation as on the precision of your day listed.)
Notably, the ITK-Amorphispironon E elaborate exhibited essentially the most restricted conformational sampling throughout both eigenvectors, occupying only 32% of the section Place relative to apo ITK. This minimized variance indicates enhanced structural rigidity and thermodynamic stabilization on ligand binding, most likely reflecting optimized molecular complementarity.
