| 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. |

[Chemical constituents from stem barks of Vernonia cumingiana].[Pubmed:20822012]
Zhongguo Zhong Yao Za Zhi. 2010 Jun;35(11):1421-4.
The chemical constituents from the stem barks of Vernonia cumingiana were investigated. Various chromatographic techniques such as silica gel chromatography, Sephadex LH-20, ODS column chromatography and HPLC were used to isolate and purify the constituents. The structures were elucidated by spectral methods. Twelve compounds were isolated from the 95% ethanol extract and their structures were elucidated as methyl 3,5-dicaffeoylquinate (1), mEthyl 3,4-dicaffeoylquinate (2), Ethyl 3,4-dicaffeoylquinate (3), methyl 3,4,5-tricaffeoylquinate (4), stigmasterol (5), alpha-spinasterol (6), beta-sitosterol (7), 24-methylene-lanosta-9 (11)-en-3beta-acetate (8), ethyl gallate (9), di-n-butyl-phthalate (10), stearic acid (11) and palmitic acid (12). Compounds 1-12 were isolated from this plant for the first time.
