Serratenes from the stem bark of Picea Jezoensis carr. hondoensis
Abstract A new triterpene ketol was isolated along with two known triterpenes, 3,21-diepiserratenediol and 21- episerratenediol from the stem bark of Picea jezoensis Carr. hondoensis , and theExpand
Two serratane triterpenes from the stem bark of Picea jezoensis var. hondoensis
Two serratane triterpenoids were isolated from the stem bark of Picea jezoenis var. hondoensis, together with two known compounds, 3β-methoxyserrat-14-en-21-one and 3β-methoxyserrat-14-en-21α-ol. TheExpand
A new serratane-type triterpene from Lycopodium phlegmaria
Lycophlegmarin exhibited modest growth-inhibitory activity in vitro against human hepatoma cells BEL 7402 and was elucidated on the basis of detailed spectroscopic analysis and chemical method. Expand
3-oxo-serratene triterpenoids from the stem bark of Picea jezoensis Carr. hondoensis
Abstract The stem bark of Picea jezoensis Carr. hondoensis contained two new triterpenoids besides sitosterol and three known serratane derivatives, 3α-methoxyserrat-14-en-21-one,Expand
Diterpenoid acids from Pinus koraiensis
Two new diterpenoid acids, pinusenocarp (1) and pinusenoid (2), were isolated from the pine cone of Pinus koraiensis. All the compounds were characterized on the basis of spectral analysis, viz. 1HExpand
Note: A new diterpenoid and active stilbenes from Pinus armandii heartwood
8(17),13-Labdadien-16,14-olid-18-oic acid (1), a new diterpenoid, has been isolated from the heartwood of Pinus armandii Francher and showed significant inhibition against white-rot fungi. Expand
Serratene-type triterpenoids from Palhinhaea cernua.
Phytochemical investigation of the 95% ethanol extract of the whole plant of Palhinhaea cernua afforded five new serratene-type triterpenoids together with four known analogues, elucidated by extensive spectroscopic analysis and X-ray crystallographic data. Expand
Identification of Serratane Synthase Gene from the Fern Lycopodium clavatum.
The result suggested that serratanes are directly biosynthesized from pre-α-onocerin and not from α-onOCerin as previously assumed. Expand
Polyfunctional triterpenoids from the bark of Yeddo spruce
The composition of the polyfunctional triterpenoids of an extract of the Yeddo spruce has been studied. Five serratene triterpenoids have been isolated: 21β-hydroxyserrat-14-en-3-one (I),Expand
Triterpenoids from the fern Goniophlebium mengtzeense
Two new triterpenoids were isolated from the fresh fronds of Goniophlebium mengtzeense and their structures were established by spectroscopic techniques and chemical correlation. Expand


New serratane triterpenes from western white pine bark
Abstract Three new serratanes were isolated from the nonsaponifiable fraction of western white pine ( Pinus monticola Dougl.) bark. The compounds were shown to be 3β-methoxyserrat-14-ene-21α,30-diolExpand
Flavonoids and stilbenes from armand pine
Abstract Seven flavonoids and seven stilbenes were isolated from the heartwood of Pinus armandii Fr. var. mastersiana Hay. Among them, trans -3,5-dimethoxystilbene oxide is a new compound andExpand
Mass spectral fragmentation studies of triterpenes related to serratenediol
Abstract A detailed investigation of the mass spectral fragmentation patterns of triterpenes of the serratenediol family has been carried out This study reveals that the application of massExpand
