Three resin glycosides isolated from Argyreia acuta, including two isomers.[Pubmed: 29860996]
In the present study, three compounds were isolated from Argyreia acuta, among them, compounds 1 and 2 were new and Compounds 1 and 3 were isomers. They were separated by several types of columns, such as normal phase, RP, size exclusion and preparative HPLC, and their structures were elucidated by several spectroscopic methods, such as 1D- and 2D-NMR and HR-TOF-MS.

Three new resin glycosides compounds from Argyreia acuta and their α-glucosidase inhibitory activity.[Pubmed: 27400121]
Three new phenolic compounds, acutacoside C (1), acutacoside D (2) and acutacoside E (3) were isolated from the aerial part of Argyreia acuta. The oligosaccharide chain was composed of two glucoses and three rhamnoses, and the aglycone was (11S)-hydroxyhexadecanoic acid (jalapinolic acid). The core of the three compounds was operculinic acid B, which was rare in resin glycosides. Their structures were established by a combination of spectroscopic and chemical methods. Compounds 1-3 have been evaluated for inhibitory activity against α-glucosidase, which all showed weak inhibitory activities.
