摘要：

Two new diterpene glycosides containing 20-hydroxygeranuyllinalool were isolated and identified from Nicotiana tabacum. These compounds consisted of five molecules of glucose and/or rhamnose. The locations of the aglycone and glycosides in the molecules were determined by 2D-NMR with the HMBC technique. The structures were (6E,10E,14Z)-20-hydroxygeranyllinalyl-3-O-[alpha-L-rhamnopyranosyl (1-->4)]-beta-D-glucopyranoside-20-O-[beta-D-glucopyranosyl (1-->2)]-[alpha-L-rhamnopyranosyl (1-->6)]-beta-D-glucopyranoside and (6E,10E,14Z)-20-hydroxygeranyllinalyl-3-O-[alpha-L-rhamnopyranosyl (1-->4)]-beta-D-glucopyranoside-20-O-[alpha-L-rhamnopyranosyl (1-->4)]-[alpha-L-rhamnopyranosyl (1-->6)]-beta-D-glucopyranoside.
