| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

[Simultaneous determination of three coumarin constituents in roots of Peucedanum praeruptorum by RP-HPLC].[Pubmed:19685749]
Zhongguo Zhong Yao Za Zhi. 2009 May;34(9):1121-3.
OBJECTIVE: To develop a reserved-phase HPLC method for the determination of praeruptorin A, praeruptorin B, Qianhucoumarin E in roots of Peucedanum praeruptorum. METHOD: Agilent TC-C18 column (4.6 mm x 250 mm, 5 microm) was used at 30 degrees C with the mobile phase of methanol-water (75:25). The flow rate was set at 0.8 mL x min(-1). The detection wavelength was 321 nm. RESULT: The linear response ranged from 3.20-28.80 microg for +/- praeruptorin A (r = 0.9999, n = 5), 1.60-14.40 g for praeruptorin B (r = 0.9995, n = 5) and 1.64-14.76 g for Qianhucoumarin E (r = 0.9994, n = 5), respectively. Recoveries were 98.92% with RSD 1.6% for praeruptorin A, 99.66% with RSD 1.5% for praeruptorin B and 99.72% with RSD 1.4% for Qianhucoumarin E. CONCLUSION: The method is quick, simple and repeatable for determination of three coumarin constituents in root of P. praeruptorum.
