چکیده
In continuation of earlier works1) an unknown compound, C20H340, m・P・ 182~183。, [α]15D +14.52°,obtained from the neutral portion of wooe resin of Cryptmeria japonica D. Don, has been examined. In part VIII1) of this series, an isolation of this compound has been described in detail. This compound, called phyllocladanol, is not apparent to have been previously isolated. Phyllocladanol is colorless needles being soluble in ether and chloroform, less soluble in methanol, and give a negative LiebermannBurchard reaction. In view of this molecular formula and co-existence in wood with other diterpenoids, e. g. ferruginal and xanthoperol, it is probable that phyllocladanol is one of diterpenes having a polycyclic carbon skeleton.

New diterpenoids from the aerial parts of Salvia reuterana
The genus Salvia is a valuable origin of structurally diverse terpenoids. In a project directed at structurally interesting bioactive metabolites from Iranian Salvia species, we studied Salvia reuterana. Two new labdane diterpene, 6β,14α-dihydroxy-15-acetoxysclareol (1), and 14α,15- dihydroxy sclareol (2), were isolated from the aerial part of the plant. Their structures were established mainly...
متن کاملA Novel Diterpene Glycoside with Nine Glucose Units from Stevia rebaudiana Bertoni
Following our interest in new diterpene glycosides with better taste profiles than that of Rebaudioside M, we have recently isolated and characterized Rebaudioside IX-a novel steviol glycoside-from a commercially-supplied extract of Stevia rebaudiana Bertoni. This molecule contains a hexasaccharide group attached at C-13 of the central diterpene core, and contains three additional glucose units...

In our search for new anticancer medicinal plants, the antiproliferative activity of the methanol extract of Daphne mucronata (Thymelaeaceae) was evaluated using human myelogenous leukemia K562 cells. The cells responded to plant treatments in a dose dependent manner and the IC50 of the crude extract (equivalent to 1 g of plant leaves powder per ml) and the purified active component were found ...
