In continuation of research on polysaccharides from plants of the family Lamiaceae [1, 2, 3], we studied water-soluble polysaccharides from the aerial part of Panzerina lanata (L.) Sojak.

The aerial part of P. lanata was collected in August 2008 near the village of Atsagat (Buryatiya, Russia). Optical rotation was determined on an SM-3 polarimeter (Zagorsk Optico-Mechanical Plant). Spectrophotometric studies were performed on a UV-Vis-mini spectrophotometer (Shimadzu). IR spectra were recorded from films on KRS-5 plates in the range 4000–450 cm–1 on a Spectrum 100 Fourier-IR spectrometer (Perkin–Elmer). 13C NMR spectra were recorded on a VXR 500S NMR spectrometer (Varian) at operating frequency 125.7 MHz. Spectra were taken from solutions (1%) in DMSO-d6. GC–MS analysis of methylated monosaccharides was carried out in a 5973 N GC–MS (Agilent Technologies) with a 6890N mass-selective detector (Agilent Technologies) with a diffusion pump and PH-Innowax capillary column (30 m/250 μm/0.50...
