In an article, author is Wang, Hongxun, once mentioned the application of 6976-37-0, HPLC of Formula: https://www.ambeed.com/products/6976-37-0.html, Name is BIS-TRIS, molecular formula is C8H19NO5, molecular weight is 209.24, MDL number is MFCD00002853, category is amides-buliding-blocks. Now introduce a scientific discovery about this category.
Abri herba originates from Abrus mollis and Abrus cantoniensis. Its leaves are rich in amides and they are often used as folk food ingredients and tea in China. However, the effective analysis methods for amides have not been reported. An UPLC method was developed to obtain the fingerprint profiles and to quantify these amides. Twenty common peaks were identified and analyzed by similarity, hierarchical clustering, and principal component analysis of UPLC fingerprints from 24 samples. Furthermore, four amides were simultaneously quantitated by Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Heat Map. The similarity of the fingerprints ranged from 0.734 to 0.989. The contents of amides were affected by the origins of the samples, and the closer the origin, the higher similarity of amide profiles. (E)-N-(4-hydroxycinnamoyl) tyrosine was the major compound ranging from 0.75 to 6.36 mg g(-1), followed by abrusamide A (0.44 similar to 1.14 mg g(-1)), abrusamide B (0.35 similar to 0.75 mg g(-1)), and abrusamide C (0.05 similar to 0.25 mg g(-1)). This is the first report to fingerprints and quantification analytical method of amides in leaves of abri herba.
