Flavonoids, a class of polyphenolic compounds produced by phenylalanine metabolism, play an important role in physiological processes in plants, such as root growth, flower pollination, pathogenic bacteria and UV stress. Natural flavonoids exist mostly in the form of glycosides and can form a variety of flavonoid glycosides depending on the type, amount, linkage position and linkage mode of the sugars. BOC Sciences used HPLC-MS for absolute quantification of flavonoid monomers.
Flavonoids can be determined by UV spectrophotometry, thin layer chromatography, high performance liquid chromatography (HPLC), capillary electrophoresis, and liquid chromatography-mass spectrometry (HPLC-MS).
Currently we can provide the following flavonoid natural products by HPLC-MS.
|12||Sacred herb hypoglycoside||28||Naringenin dihydrochalcone|
|13||Sacred herb phenol||29||Mulberry pigment|
We will provide a detailed technical report at the end of the project, which will include:
Samples should be placed in appropriate sample tubes with the name of the sample and other relevant information on the tube. It is recommended that all sample tubes be secured in 50 ml centrifuge tubes with caps before shipping, and that the 50 ml tubes be placed in sealed bags.
Double marking, send sample tubes and bags with sample numbers clearly written; samples should not be named with simple letters or data, such as A/B/C or 1/2/3, but require samples to be named with letters plus numbers numbering, such as A1, to avoid duplication.
The sample technical requirement form must be mailed with the samples. Avoid prolonging the project cycle due to the inability to check the information in time.
If you have a requirement about our services, please contact us by phone or email, our colleagues will reply to you within three working days.
