Resin glycosides from the morning glory family.

Four Pentasaccharide Resin Glycosides from Argyreia acuta.

Four pentasaccharide resin glycosides, acutacoside F-I (1-4), were isolated from the aerial parts of Argyreia acuta. These compounds were characterized as a group of macrolactones of operculinic acid A, and their lactonization site of 11S-hydroxyhexadecanoic acid was esterified at the second saccharide moiety (Rhamnose) at C-2. The absolute configuration of the aglycone was S. Their structures ...

Ether-soluble resin glycosides from the roots of Ipomoea batatas.

Two new resin glycosides, batataosides I (1) and II (2), and five known compounds, friedelin (3), scopoletin (4), octadecyl caffeate (5), beta-sistosterol (6) and daucosterol (7), were isolated from the roots of Ipomoea batatas. Their structures have been determined based on the chemical and spectral data. Batataosides I and II have novel structures because the core simonic acid B was esterised...

Crypthophilic acids A, B, and C: resin glycosides from aerial parts of Scrophularia crypthophila.

The water-soluble part of the methanolic extract from the aerial parts of Scrophularia crypthophila, through chromatographic methods, yielded three new resin glycosides, crypthophilic acids A - C (1-3). Compounds 1-3 are tetraglycosides of (+)-3S,12S-dihydroxypalmitic acid. The structures of these and 10 known compounds were elucidated by spectroscopic and chemical means. All natural resin glyc...

Cardiac Glycosides in Medicinal Plants

Plant active metabolites are under intensive examinations around the world to supplement the drugs with minimal side effects. Thus, there is vast potential to explore the possible medicine from the plant sources. Cardiac glycosides are a unique group of secondary metabolites that they are considered one of the most useful drugs in therapeutics. In this review, cardiac glycosides and their analo...
