Two new monoterpenoid glycosides from Glechoma longituba.

Chemical study on the constituents of the whole plant of Glechoma longituba (Labiatae) led to the isolation of two new pinane-type monoterpenoid glycosides, characterised as 2alpha-pinan-3-one-2-O-beta-glucopyranoside (1) and 5alpha-pinan-3-one-5-O-beta-glucopyranoside (2) along with 13 known compounds. Their structures were elucidated on the basis of spectroscopic analysis and chemical methods.
