(1984)(25R)-Isonuatigenin, a 5-spirosten-3β,25-diol, was isolated from aerial parts of Vestia lycioides. Its structure was elucidated mainly by 1H NMR and 13C NMR spectroscopy. A mixture of (25R)-nuatigenin and (25S)-isonuatigenin ...
-
(1979)Six alkaloids have been isolated from Lycopodium magellanicum. These include the known alkaloids lycopodine, acetyldihydrolycopodine, lycodine, N-methyllycodine, acetylfawcettine and a new alkaloid, 5-dehydro-magellanine. ...
-
(1984)As part of a systematic chemical investigation of Chilean Compositae (1-3), we examined the secondar chemistry of a member of the genus Gochnatia (tribe Mutisieae, subtribe Gochnatiinae): Gochnatia foliosa var. fscicularia ...
-
(1991)Seven new neoclerodanes have been isolated from aerial parts of Baccharis lejía. Four are dimeric diterpenoids linked via a C-18 malonate ester. Relevant toxicity toward Artemia salina (brine shrimp bioassay) was observed ...
-
(1980)Erythroxylol-A, oleanolic acid, erythroxylol-A oxide, scopolatine, 4-hydroxy-3-methoxyacetophenone and two new diterpenes, ent-beyer-14-en-18-ol and 19-hydroxy-13-epimanoyl oxide, were isolated from B. tola. © 1980.
-
(1990)Two new ent-labdanes were isolated from the leaves of Baccharis paniculata. The results of a chemical study of other three Baccharis species are reported. © 1990.

-
(1991)On morphological, chemical composition and field distribution studies, the hybrid condition of Baccharis χ intermedia DC. is discussed. B. linearis (Ruiz et Pavón) Pers. and B. macraei Hook, et Arn. are the parental species. ...
-
(1987)A new neo-clerodane dilactone, desoxyarticulin, and dihydrotucumanoic acid, together with other known compounds, were isolated from Baccharis pedicellata and Baccharis marginalis. The structures of the new compounds were ...
-
(1992)A novel sesquiterpene lactone, podoandin, has been isolated from the leaves of Podocarpus andina. Its structure has been established by means of spectroscopic data and confirmed by X-ray diffraction analysis. It exhibited ...
-
(1994)Seven new diterpenoids, a labdane, three isopimarenes and three rearranged isopimarenes, have been isolated from the flowering tops of Satureja gilliesii. Their structures are based on their spectroscopic properties and, ...
-
(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.
-
(2005)A series of phenethylamine derivatives with various ring substituents and with or without N-methyl and/or C-alpha methyl or ethyl groups was synthesized and assayed for their ability reversibly to inhibit monoamine oxidase ...
-
(1987)Three new tropanol dimers of mesaconic and itaconic acids and 3α-senecioyloxytropane, together with other known alkaloids, were isolated from Schizanthus grahamii. The structures of the new compounds were established by ...
-
(1980)Tropine, a pair of diastereoisomeric hygrolines and two new tropane alkaloids; 3α-senecioyloxytropan-6β-ol and 6β-angeloyloxytropan-3α-ol, were isolated from roots of Schizanthus hookeri. © 1980.
