尿石素 A (Urolithin A) 規(guī)格：HPLC>97% ；5mg Name: Urolithin A Synonyms: 3,8-Dihydroxy-6H-dibenzo[b,c]pyran-6-one Family: Hydroxycoumarins Polyphenol class: Other polyphenols Polyphenol sub-class: Hydroxycoumarins Molecular weight: 228.2 Chemical Formula: C13H8O4 CAS Number: 1143-70-0 簡(jiǎn)介 Urolithin A is an urolithin, a type of microflora human metabolite of dietary ellagic acid derivatives,[1][2] such as ellagitannins.[3] During intestinal metabolism by bacteria, ellagitannins and punicalagins are converted to urolithins, which have unknown biological activity in vivo.[4][5] Urolithin A glucuronide is found in plasma at low concentrations.[6] Family: Hydroxycoumarins Polyphenol class: Other polyphenols Polyphenol sub-class: Hydroxycoumarins 參考文獻(xiàn) References 1.Larrosa, M; González-Sarrías, A; García-Conesa, MT; Tomás-Barberán, FA; Espín, JC (2006).
