||The herbs of Inula cappa
|Biological Activity or Inhibitors:
||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day.

Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: firstname.lastname@example.org
||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

|Chemical constituents from stem barks of Vernonia cumingiana.[Pubmed: 20822012]|
|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.
