A New Bezoxepine Derivative from Senecio desfontainei
Phytochemical investigation of the aerial parts of Senecio desfontainei afforded one new benzoxepine derivative, senecioside (1) along with eleven known compounds (2-12). Their structures were assigned from H and C NMR spectra, DEPT and 2D COSY, NOE, HSQC and HMBC NMR experiments. All these compounds were tested for antioxidant activity in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scaven...
متن کاملSaponins and Sapogenins from Brachiaria decumbens Stapf
Quatro saponinas esteroidais e três sapogeninas foram identificadas das partes aéreas de Brachiaria decumbens. As estruturas desses compostos foram estabelecidas através de métodos químicos e espectroscópicos (RMN de H e C, HMBC, HMQC) como 3 -metóxi-lanost-9(11)-eno (1), diosgenina (2a), iamogenina (2b), 3-O-D-glicopiranosil-24(S)-etil-22E-deidrocolesterol (3a), 3O-D-glicopiranosil-24(R)-etil-...
متن کاملCyclopenicillone, a unique cyclopentenone from the cultures of Penicillium decumbens.
Cyclopenicillone (1), possessing a unique 2,5-dimethylcyclopent-2-enone carbon skeleton, has been isolated from the cultures broth of the fungus Penicillium decumbens. The structure and absolute configuration of 1 were elucidated using a combination of NMR spectroscopy, CD data and computational approaches. Cyclopenicillone (1) demonstrated a dose-dependent (10-100 μM) inhibition against LPS-in...
متن کاملThe minor ecdysteroids from Ajuga turkestanica.
INTRODUCTION Ajuga turkestanica is a plant used in traditional medicine for its high ecdysteroid content, including the presence of the particularly active turkesterone, which possess efficient anabolic activity. OBJECTIVES To isolate and identify minor ecdysteroids present in a semi-purified plant fraction containing ca. 70% turkesterone. MATERIAL AND METHODS Multi-step preparative HPLC (c...
متن کاملA clerodane diterpene with antibacterial activity from Ajuga lupulina.
The structure of a new diterpene, C30H46O11, with antibacterial activity against Pseudomonas aeruginose and Escherichia coli, isolated from the fresh whole plants of Ajuga lupulina (Labiatae) was established to be 2 beta-hydroxy-2-methylbutanoyl-3 alpha-lupulin (3-deoxy-14,15-dihydro-2-hydroxy-15-methoxycaryoptinol 2-methylbutanoate), by means of X-ray crystallographic analysis. The present stu...
