A program for terpenoid skeleton prediction based on botanical information
(2003-01-01)
This paper describes a new program developed to the SISTEMAT expert system, the SISOCBOT program. This program employs the botanical data analysis and predicts, at the end of analysis, the probable skeleton of a compound ...
Seco-, nor-, normal and rearranged labdanes from Haplopappus parvifolius
(1991)
The aerial parts of Haplopappus parvifolius afforded 30 new diterpenes including 21 labdane derivatives, four nor-diterpenes, three rearranged ones, four seco-labdanes and one with a new carbon skeleton whose structure was ...

Automatic identification by C-13 NMR of substituent groups bonded in natural product skeletons
(Elsevier B.V., 2002-11-01)
The aim of this paper is to present a procedure that utilizes C-13 NMR for identification of substituent groups which are bonded to carbon skeletons of natural products. For so much was developed a new version of the program ...
Spartidienedione, a new sesquiterpene with a novel carbon skeleton from Baccharis spartioides
(1993)
Spartidienedione, a new sesquiterpene possessing a novel carbon skeleton, was isolated from the aerial part of Baccharis spartioides and its structure established by spectroscopical methods. © 1993.
