Two New Phenolic Glycosides from Sorbus commixta.

From the stem bark of Sorbus commixta, two new phenolic glycosides, sorcomisides A and B (1 and 2), were isolated along with 10 known compounds. The structures of the isolates were determined by analysis of one-dimensional and two-dimensional NMR (1D- and 2D-NMR) data and high resolution (HR)-MS, chemical reaction, and computational methods. All the isolated compounds (1-12) were tested for their neuroprotective, anti-inflammatory, and cytotoxic activities.
