ENT-LABDANE-TYPE DITERPENE GLUCOSIDES FROM LEAVES OF RUBUS CHINGII

Previuosly, a sweet steviol bisglucoside named rubusoside was isolated from leaves of a Chinese Rubus spp. which was tentatively assigned as R. chingii.From leaves of Japanese Rubus chingii (Japanese name Gosho-Ichigo) which are not sweet, five ent-labdane-type diterpene glucosides named goshonosides F1-5 were isolated instead of rubososide and their structures were elucidated.The name 'R. suavissimus' has been proposed for the Chinese plant.Key Word Index - Rubus chingii; Rubus suavissimus; Rosaceae; glucosides of ent-labdane type diterpenes; goshonosides F1-5.

Agathadiol, a labdane diterpenoid from juniper berries, is a positive allosteric modulator of CB1R

The neutral fraction of a juniper (Juniperus communis L.) berries acetone extract could positively modulate the activity of type 1 - cannabinoid receptor (CB1R). Bioactivity-directed fractionation identified the labdane diterpenoid agathadiol (4) as a positive allosteric modulator of CB1R, while closely related analogues were inactive. Agathadiol (4) is a minor constituent of juniper, but could be more conveniently obtained by semisynthesis from agathic acid (8), a major constituent of Manila copal.

DERIVATIVES OF ANTICOPALIC ACID AND OTHER NEW COMPOUNDS FROM THE OLEORESIN OF Pinus pumila

From the oleoresin of the Japanese stone pine the previously known agatholic, agathalic, agathic and 3β-hydroxyanticopalic acids, and also the new acids 19-methoxyanticopalic and 19-O-succinylagatholic acids have been isolated and identified in the form of their methyl esters.Two new esters of 1-borneol have been isolated and characterized in the form of their acetates - the ferulate and the p-coumarate.
