Assignment of 13C and 1H Chemical Shifts of Potassium Sodium  Dehydroandrographolide Succinate

Abstract

Abstract:

Potassium sodium dehydroandrographolide succinate (PSDS) is a new antibacterial and antiviral agent derived from andrographolide, a compound found in the extract of medicinal herb Andrographis paniculata (Burm. f.) Nees. In this study, the ¹³C and ¹H chemical shifts of the compound were assigned using 1D NMR and 2D NMR techniques including gCOSY, gHSQC, gHSQC-TOCOSY and gHMBC. Its structure was determined from the NMR data.

Key words: 2D NMR, chemical shift assignments, potassium sodium dehydroandrographolide succinate, andrographolide

CLC Number:

O561.1
