| 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. | ||
The whole plants of Gentiana urnula.
| Description | Gentiournoside D is a natural product from Gentiana urnula. |
| Structure Identification | Acta Botanica Yunnanica,1994,16(4):417-423.Five iridoidal glycocosides from Gentiana urnula.[Reference: WebLink]Five new iridoidal glycosides, gentiournoside A, gentiournoside B, gentiournoside C, Gentiournoside D, gentiournoside E were isolated from the whole herb of Gentiana urnula. Their structures were elucidated mainly by spectral methods. Among which gentiournoside A, gentiournoside B, gentiournoside C are bis-iridoidal glycosides while Gentiournoside D and gentiournoside E are loganin type ones. It is noted that all the glycosides possess a 2,3-dihydroxy benxoyl benxoyl unit or its derivative in the molecule. |

Five iridoidal glycocosides from Gentiana urnula.
Acta Botanica Yunnanica,1994,16(4):417-423.
Five new iridoidal glycosides, gentiournoside A, gentiournoside B, gentiournoside C, Gentiournoside D, gentiournoside E were isolated from the whole herb of Gentiana urnula. Their structures were elucidated mainly by spectral methods. Among which gentiournoside A, gentiournoside B, gentiournoside C are bis-iridoidal glycosides while Gentiournoside D and gentiournoside E are loganin type ones. It is noted that all the glycosides possess a 2,3-dihydroxy benxoyl benxoyl unit or its derivative in the molecule.
