BZXD Marker Component Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
According to the Pharmacopoeia of the People's Republic of China (2020 edition), six main components in BZXD have been identified. The quality stability and repeatability of these six marker components were detected by UPLC-MS/MS analysis method. We purchased the standard reference materials of Rosmarinic acid, Paeoniflorin, Glycyrrhizic acid, Salvianolic acid B, p-Coumaric acid, and Ferulic acid from Yuanye Bio-Technology Co., Ltd. (Shanghai, China). Qualitative analysis was carried out using an AB Sciex API 4000 LC/MS/MS system. Analytes were separated using a linear gradient program at a flow rate of 0.30 ml/min using a mobile phase consisting of 2 mmol/l ammonium acetate in water (A) and acetonitrile (B).
Precisely pipette 0.200 ml of thawed BZXD concentrate at 4 °C into a 2 ml brown PE tube, 0.6 ml mass spectrometry grade acetonitrile solution, and vortex for 5 min. Centrifuge at 13000r/min at 4 °C for 20 min. Take the supernatant and dilute it by 4 times, shake and mix, and filter through a 0.22-micron filter to be tested. The samples were detected and analyzed by negative ion electrospray tandem mass spectrometry (Supplementary Figure S1).

HPLC was performed using the Ultimate 3000 system (Thermo Fisher Scientific, Inc.). The reference substances neochlorogenic acid, chlorogenic acid, rutin, isoquercitrin, astragaloside and rosmarinic acid (20 mg of each substance; Shanghai Yuanye Bio-Technology Co., Ltd.) were weighed and added to methanol at a chromatographic level of 2 ml. The reference substances were dissolved by full oscillation and reference substance reserve solutions were obtained. The two mobile phase solvents were: Mobile phase A, 0.5% acetic acid water; mobile phase B, acetonitrile. The flow rate was 0.5 ml/min. Accucore™ C18 chromatography columns (particle size 2.6 µm; dimensions, 4.6×150 mm; Thermo Fisher Scientific, Inc.) were used. The injection volume was 10 µl and the column temperature was 30°C. The detection wavelength was 328 nm and the gradient conditions 0–30 min, 12–45% (phase B); 30–35 min, 45–100% (phase B); 35–40 min, 100% (phase B) were used to determine the components of the AVP.

Check if the same lab product or an alternative is used in the 5 most similar protocols
This study was approved by the Committee on the Ethics of Animal Experiments of
Guangxi Medical University (permit no. 201711014; Nanning, China). A total of
240 male specific pathogen-free Sprague-Dawley rats (9 weeks old, weighing 230 ±
20 g) were purchased from the Laboratory Animal Center of Guangxi Medical
University. The rats were housed in suspended plastic cages at 22°C to 24°C and
50% to 60% humidity on a 12-hour light/dark cycle. Food and water were provided
ad libitum. The rats were randomly divided into 6 groups: the control (Ctrl)
group, the (IR alone) group, the IR + 30, 60, and 120 mg/kg RA (IR and 30, 60,
and 120 mg/kg RA, respectively) groups, and the IR + AMI (irradiation and
Amifostine) group. Rosmarinic acid (Shanghai Yuanye Biotechnology, Shanghai,
China) was compounded with saline and was intragastrically administered 7 days
before IR and until the rats were sacrificed. Amifostine (Sigma-Aldrich, St.
Louis, MO; 250 mg/kg body weight in 1 mL saline solution) was intraperitoneally
administered 30 minutes before IR, which is effective and well tolerated by rats
to prevent saliva-flow dysfunction according to the previous research.25 (link) Eight rats from each group were randomly sacrificed at each time point
(the 3rd, 10th, 30th, 60th, and 120th day after IR).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
