Terpenoids from Nepeta tuberosa subsp.reticulata (II)

Four new diterpenoid compounds have been isolated from Nepeta tuberosa subsp.reticulata and their structures elucidated by spectroscopic methods and chemical correlations as abietatrien-3β-ol, isopimara-8,15-dien-7β,18-diol, isopimara-8,15-dien-7α,18-diol and 7α-hydroxy-isopimara-8(14), 15-dien-18-yl malonate. We have also isolated the known terpenoids acetyl isocupressic acid, isopimara-8(14),15-dien-7α,18-diol, phytol, ursolic acid, and the steroids sitosterol and sitosterol glucoside.
