||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).
Whenever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. 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: email@example.com
||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.
Calculate Dilution Ratios(Only for Reference)
* Note: If you are in the process of experiment, it's need to make the dilution ratios of the samples. The dilution data of the sheet for your reference. Normally, it's can get a better
solubility within lower of Concentrations.

|Development of high-performance liquid chromatographic for quality and authenticity control of Chinese propolis.[Pubmed: 24894633]|
| The flavonoid profiles of poplar tree gum were found to be similar to those of propolis, which are dominated by pinobanksin, pinocembrin, 3-O-Acetylpinobanksin, chrysin, and galangin. Therefore, the proposed method could be applied to exclude poplar tree gum from propolis with cafferic acid, ferulic acid, and p-coumaric acid as qualitative markers, and distinguish poplar source resin from other illegal substances, and evaluate the quality grading of poplar-type propolis with pinobanksin, pinocembrin, 3-O-Acetylpinobanksin, chrysin, and galangin as qualitative and quantitative markers.

|A new flavonone from seeds of Alpinia katsumadai and its neuroprotective effect on PC12 cells.[Pubmed: 25272494]|
|A new flavonone, named as (2R, 3S)-pinobanksin-3-cinnamate(1), together with six known compounds, pinocem-brin (2), pinobanksin (3), 3-O-Acetylpinobanksin (4), galangin (5), kumatakenin(6), and 3-methylkaempferol (7), were isolated from a 95% ethanol extract of seeds of Alpinia katsumadai through a combination of various chromatographic techniques, including silica gel and Sephadex LH-20. The structure of compound 1 was elucidated by spectroscopic data analysis. Compound 1 exhibits a potent neuroprotective effect against the corticosterone-damaged PC12 cells, which may be underlying the effect by scavenging intracellular ROS.

|Negative ion 'chip-based' nanospray tandem mass spectrometry for the analysis of flavonoids in glandular trichomes of Lychnophora ericoides Mart. (Asteraceae).[Pubmed: 18980260]|
|This paper reports a method for the analysis of secondary metabolites stored in glandular trichomes, employing negative ion 'chip-based' nanospray tandem mass spectrometry. The analyses of glandular trichomes from Lychnophora ericoides, a plant endemic to the Brazilian 'cerrado' and used in traditional medicine as an anti-inflammatory and analgesic agent, led to the identification of five flavonoids (chrysin, pinocembrin, pinostrobin, pinobanksin and 3-O-Acetylpinobanksin) by direct infusion of the extracts of glandular trichomes into the nanospray ionisation source.
