Antibiotic activity and absolute configuation of 8S-heptadeca-2(Z),9(Z)-diene-4,6-diyne-1,8-diol from Bupleurum salicifolium.
A polyacetylene has been isolated from Bupleurum salicifolium. Its structure and absolute configuration were determined to be 8S-heptadeca-2(Z),9(Z)-diene-4,6-diyne-1,8-diol [1] by means of 1H- andExpand
Busaliol and Busalicifol, Two New Tetrahydrofuran Lignans from Bupleurum salicifolium
-Three tetrahydrofuran lignans [l-3} were obtained from the leaves of Bupleu17lm salici!olium, of which busaliol {l} and busalicifol {2} are novel. Their structures were determined by spectral andExpand
Lignanolides from bupleurum salicifolium
Abstract Three new lignans isolated from the roots of Bupleurum salicifolium were characterised as guamarol, isoguamarol and guamarolin on the basis of chemical and spectral evidence. The knownExpand
New Lignan Butenolides from Bupleurum salicifolium
Three new lignans were obtained from the roots of Bupleurum salicifolium (Umbelliferae). Two proved to be butenolides, methylchasnarolide [1] and chasnarolide [3], and the other, a γ-butyrolacrone,Expand
Macrocarpins A-D, new cytotoxic nor-triterpenes from Maytenus macrocarpa.
Macrocarpins A (1), B (2), C (3) and D (4), four new nor-triterpenes, have been isolated from the roots of Maytenus macrocarpa. The structures were established by spectroscopic examinations. NaturalExpand
Biological activities of some Argyranthemum species.
Seven species of the genus Argyranthemum were studied for antimicrobial and cytotoxic activities. Argyranthemum adauctum, A. foeniculaceum and A. frutescens showed antimicrobial activity againstExpand
Biological activity of secondary metabolites from Bupleurum salicifolium (Umbelliferae).
Secondary metabolites from Bupleurum salicifolium were tested against viruses, Gram-positive and Gram-negative bacteria, the yeast Candida albicans, the nematodes Globodera pallida and G.Expand
Isokaerophyllin, a butyrolactone from Bupleurum salicifolium
Abstract From the leaves of Bupleurum salicifolium two benzylidene-benzyl-γ-butyrolactone-type lignans were isolated. One was identified as kaerophyllin, the other as its cis-isomer, hithertoExpand
13C NMR assignments of some dibenzyl-γ-butyrolactone lignans
Abstract 1 H 13 C heteronuclear correlation and long-range correlation spectra with inverse detection, allowed the unequivocal assignment of 13 C spectra of some dibenzyl-γ-butyrolactones isolatedExpand
