Naoshuantong capsule (NSTC) is an oral traditional Chinese medicine formula used widely in the clinic for ischemic stroke. The absorbed ingredients and metabolites of NSTC have never been reported before. In this study, a method incorporating rapid resolution liquid chromatography with quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF/MS) was used to identify absorbed ingredients and metabolites after oral administration of NSTC. A total of 15 constituents were detected and identified as prototypes of NSTC. 109 metabolites related to catechin, gallic acid, paeoniflorin, chlorogenic acid, protocatechuate, typhaneoside, β-elemene, calycosin were identified in serum, urine and brain. 19 metabolites of typhaneoside, 3 metabolites of β-elemene, 12 metabolites of calycosin were reported for the first time. This is the first time to explore the absorption and metabolism of NSTC. The work will provide helpful information for further research of the mechanism and application of NSTC.

Typhae Pollen (TP) and Trogopterus Feces (TF) are well-known traditional medicine in china which widely used for thousands of years as drug pair called Shixiao San for treatment of blood stasis syndrome, specially shown great efficacy in gynecological disease. Typhaneoside, vanillic acid and p-coumaric acid are the main bioactive components of Typhae Pollen. This study was carried out for comparing the pharmacokinetic profile of these three major bioactive components in rats after oral administration of Typhae Pollen-Trogopterus Feces (TP-TF) drug pair before and after compatibility.
A sensitive and rapid UPLC-TQ/MS method has been developed for simultaneous quantification of the three main bioactive compounds in blood at different time points after oral administration of Typhae Pollen (TP) and the combination with Trogopterus Feces (TF).
There were significant differences of C(max), T(max), T(1/2) and AUC(0~t) for three bioactive compounds among the groups, for typhaneoside with the most highest plasma concentration of 370.86 ± 315.71 ng/mL and more longer T(max) in TP-TF co-decoction group (C(M)); for vanillic acid, TP-TF co-decoction group (C(M)) had a good absorption with C(max) (3870.99 ± 2527.99 ng/mL) and T(max) (1.47 ± 3.20 h); for p-coumaric acid, it had similar pharmacokinetic characteristics with vanillic acid.
The three bioactive components in Typhae Pollen (TP) were simultaneously determined by UPLC-TQ/MS and had a good absorption in rat plasma after the combination with Trogopterus Feces (TF).

For the first time, a selective and rapid ultra-performance liquid chromatography method with tandem mass spectrometric (UPLC-MS/MS) detection for simultaneous determination of typhaneoside and isorhamnetin-3-O-neohesperidoside in rat plasma was developed and validated, which was applied to the pharmacokinetic study of Pollen Typhae extract. The separation was carried out on an ACQUITY UPLC(TM) BEH C18 column with gradient elution using mobile phase including acetonitrile and water (containing 0.1% formic acid). The flow rate was 0.4 mL/min. The detection was conducted by means of electrospray ionization mass spectrometry in negative ion mode with multiple reaction monitoring. The assays were linear over the concentration range of 0.5-100 ng/mL, and the lower limit of quantification was 0.5 ng/mL for typhaneoside and isorhamnetin-3-O-neohesperidoside. The method was validated in terms of intra- and interday precision (<9.37%), accuracy (within ±10.91%), linearity, specificity and stability, and has been successfully applied to a pharmacokinetic study of Pollen Typhae extract in rats after oral administration.

Typhaneoside, extracted from Typha angustifolia L., Typhaneoside can inhibit the excessive autophagy of hypoxia/reoxygenation cells and increase the phosphorylation of Akt and mTOR. Typhaneoside has certain effects on the cardiovascular system, including lowering blood lipid levels, promoting antiatherosclerosis activities, as well as improving immune and coagulation function.
