Simultaneous determination of aurantio-obtusin, Chrysoobtusin, obtusin and 1-desmethylobtusin in rat plasma by UHPLC-MS/MS
Biomed Chromatogr 2014 Mar;28(3):369-74.PMID:24027008DOI:10.1002/bmc.3030.
A sensitive and reliable ultra-high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UHPLC-MS/MS) method was developed and validated for the simultaneous determination of four active components of Semen Cassiae extract (aurantio-obtusin, Chrysoobtusin, obtusin and 1-desmethylobtusin) in rat plasma after oral administration. Chromatographic separation was achieved on an Agilent Poroshell 120 C18 column with gradient elution using a mobile phase that consisted of acetonitrile-ammonium acetate in water (30 mm) at a flow rate of 0.4 mL/min. Detection was performed by a triple-quadrupole tandem mass spectrometer in multiple reaction monitoring mode. The calibration curve was linear over a range of 3.24-1296 ng/mL for aurantio-obtusin, 0.77-618 ng/mL for Chrysoobtusin, 34.55-1818 ng/mL for obtusin and 1.86-1485 ng/mL for 1-desmethylobtusin. Inter- and intra-day assay variation was <15%. All analytes were shown to be stable during all sample storage and analysis procedures.
2-Hydr-oxy-1,6,7,8-tetra-meth-oxy-3-methyl-anthraquinone
Acta Crystallogr Sect E Struct Rep Online 2008 Jan 4;64(Pt 2):o371.PMID:21201403DOI:10.1107/S1600536807067864.
The title compound, C(19)H(18)O(7), also known as Chrysoobtusin, was isolated from Cassia tora L. (Leguminosae). The anthraquinone ring system is almost planar, the dihedral angle between the two benzene rings being 4.27 (4)°. The structure is stabilized by intra- and inter-molecular O-H⋯O and C-H⋯O hydrogen bonds, and by weak π-π stacking inter-actions along the b axis, with a centroid-centroid distance between related benzene rings of 3.800 (4) Å.
Discovery of potential hypoglycemic metabolites in Cassiae Semen by coupling UHPLC-QTOF-MS/MS combined plant metabolomics and spectrum-effect relationship analyses
Food Funct 2022 Oct 3;13(19):10291-10304.PMID:36125104DOI:10.1039/d2fo00562j.
Cassiae Semen (CS) is consumed as fried tea or medicinal food in Asian areas. Its two commercial forms, namely raw and fried CS, exert different clinical applications, in which fried CS is commonly applied as a functional tea for losing weight. To prevent confusion in the use of the two forms of CS, a comprehensive strategy by combining plant metabolomics and spectrum-effect relationship analyses was developed for the fast and efficient discrimination of raw and fried CS, and further for the discovery of the potential hypoglycemic metabolites of CS to control its quality. First, the plant metabolic profiling of raw and processed samples was performed by UHPLC-QTOF-MS/MS. A total of 1111 differential metabolites were found to well distinguish the raw and fried CS after analyzing by MPP software. Subsequently, α-glucosidase inhibition of raw and fried CS was investigated. As a result, fried CS demonstrated much stronger α-glucosidase inhibition activity than the raw sample. By analyzing the spectrum-effect relationship with GRA, BCA, and PLSR, 14 potential hypoglycemic-related compounds were discovered. As anticipated, they were also found as the differential metabolites of the raw and fried samples with a potential hypoglycemic effect, which might be beneficial for the quality control of CS tea. Additionally, molecular docking analysis was conducted to reveal the underlying inhibition mechanisms of the four most critical constituents, including physcion, Chrysoobtusin, aurantio-obtusin, and obtusifolin. This study provides a powerful tool for the discrimination of processed samples and fast screening of the active constituents in complex natural products on a high-throughput basis.
Nine components pharmacokinetic study of rat plasma after oral administration raw and prepared Semen Cassiae in normal and acute liver injury rats
J Sep Sci 2019 Jul;42(14):2341-2350.PMID:31037812DOI:10.1002/jssc.201900007.
In China, Semen Cassiae has long been used to protect liver, brighten eyes, and relieve constipation. Prepared Semen Cassiae is produced from raw Semen Cassiae by processing, the two forms of Semen Cassiae have different clinical applications. Pathological state is an important factor affecting the efficacy of drugs, the pharmacokinetic behavior of drugs could be significantly changed when people or animal were under different pathological state. To clarify the effect of processing mechanism and pathological state for pharmacokinetic behavior, the pharmacokinetics of nine components of raw and prepared Semen Cassiae under normal and acute liver injury rats were examined. The results showed that the bimodal phenomenon appeared on the plasma concentration-time profiles of obtusin, emodin, chrysophanol, aloe emodin and rhein. The Tmax of aurantio-obtusin, obtusin, Chrysoobtusin, emodin, chrysophanol, aloe emodin, physcion in normal groups administrated prepared Semen Cassiae were shorter than those administrated raw Semen Cassiae. For the AUC0-t , aurantio-obtusin, obtusin, Chrysoobtusin, chrysophanol, aloe emodin and physcione in model groups administrated prepared Semen Cassiae were significantly higher than other groups, unlike above components, rhein had poor absorption in model groups. The study would be useful for further studies on pharmacokinetics and clinical application of raw and prepared Semen Cassiae.
