| 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. |

Water-soluble constituents from the leaves of Ilex oblonga.[Pubmed:17613627]
J Asian Nat Prod Res. 2007 Apr-Aug;9(3-5):399-405.
Four new water-soluble constituents, oblongaroside A (1), oblongar ester A (2), Oblongaroside B (3), and oblongaroside C (4), were isolated along with four known compounds: 4-O-beta-D-glucopyranosyl-3-hydroxybenzalcohol (5), 7-methoxyl-4-O-beta-D-glucopyranosyl-3-hydroxybenzalcohol (6), 4-O-beta-D-glucopyranosyl-3-hydroxybenzoic acid (7), and 3,4-dihydroxybenzoic acid (8) from the leaves of Ilex oblonga. Identification of their structures was achieved by 1D and 2D NMR experiments, including (1)H-(1)H COSY, NOESY, HMQC, and HMBC methods and FAB mass spectral data.
