1-octen-3-O-alpha-L-arabinopyranosyl-(1 -> 6)-beta-glucopyranoside, a minor substance from the leaves of Kalanchoe pinnata (Crassulaceae)
From the leaves of Kalanchoe pinnata (Crassulaceae), a medicinal plant widely used against inflammatory processes which exhibit a important immunosuppressive and anti-leishmanial activities, was isolated a minor vinylic aliphatic alcohol diglycoside which structure was proposed as the known 1-octen-3-O-alpha-L-arabinopyranosyl-(1 -> 6)-beta-glucopyranoside based on ¹H and 13C mono and bi-dimensional NMR experiments and GC-MS analysis, after successive chromatographic column procedures. This molecule is a water-soluble derivative of the volatile aglicone 1-octen-3-ol that appears to be attractant of pollinators and signalling of defence against herbivores.
