Otophylloside B

Otophylloside B

• CAS Number: 106758-54-7
• UNSPSC Description: Otophylloside B, a C-21 steroidal glycoside isolated from Qingyangshen. Otophylloside B protects against Aβ toxicity, which decreases Aβ deposition by decreasing the expression of Aβ at the mRNA level. Otophylloside B has antiepileptic activity[1][2][3].
