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.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

[Determination of ginkgolic acids by high performance liquid chromatography].[Pubmed:12914328]

Yao Xue Xue Bao. 2002 Jul;37(7):555-8.

AIM: To establish a simple pre-treated method and high performance liquid chromatographic method for separation and determination of ginkgolic acids in Ginkgo biloba leaves. METHODS: The ginkgolic acids in the German standard sample were identified by LC/DAD/ESI/MS. The methods for pre-treatment and high performance liquid chromatography determination of ginkgolic acids were studied. Ginkgo biloba leaves were extracted with n-hexane in Soxhlet apparatus, then concentrated under vacuum. The ginkgolic acids can be determined directly by HPLC after one-pre-purified-step by silica gel column chromatography. The eluant was petroleum ether-diethyl ether-formic acid (89:11:1). The chromatographic column was Inertsil ODS-2; the mobile phase was methanol-3% acetic acid (92:8); the flow rate was 1.0 mL.min-1; the column temperature was 40 degrees C; the detection wavelength was at 310 nm. RESULTS: There were five kinds of ginkgolic acid (C13:0, C15:1, C17:2, C15:0 and C17:1) in ginkgo biloba leaves. The relative percentage content of ginkgolic acids C15:1 and C17:1 was about 85%. Ginkgolic Acid C17:2 had not been reported in China. The HPLC indicates that there was nearly no impurities except ginkgolic acids after treated by column chromatography. The results showed that the content of ginkgolic acids in the leaves of Ginkgo biloba collected in April, May and June was 1.48%, 1.19% and 1.11% respectively. The average recovery of Ginkgo biloba leaves collected in June was 97.0%, RSD was 1.7% (n = 6). CONCLUSION: The method is accurate, simple and reliable, and can be used for determination of ginkgolic acids in Ginkgo biloba leaves.
