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.
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.
