Structures of eremophilane-type sesquiterpene glucosides, alticolosides A-G, from the Far Eastern endemic Ligularia alticola Worosch.

Seven eremophilane-type sesquiterpene glucosides, alticolosides A-G, have been isolated from aerial parts of the endemic Far Eastern species Ligularia alticola Worosch. (Family Asteraceae) along with two known compounds, monoterpenoid glycoside (4S)-α-terpineol 8-O-β-D-glucopyranoside and norditerpenoid glycoside 7(8)-dihydro-β-ionone 3-O-β-D-glucopyranoside. Alticoloside D was identified with the earlier known 8-O-(β-D-glucopyranosyl)-2-oxo-eremophila-1(10),8,11-triene, but the stereostructure of the latter was revised on the basis of ROESY and CD data.

Plastid DNA variation in highly fragmented populations of Microbiota decussata Kom. (Cupressaceae), an endemic to Sikhote Alin Mountains.

Microbiota decussata Kom. (Cupressaceae) is a subalpine species endemic to the Sikhote Alin Mountains with populations scattered throughout the range. We used sequence data for four noncoding regions of chloroplast DNA to characterize the genetic diversity in populations sampled from different parts of M.
