(-)-Edunol a prenylated pterocarpan was isolated from the roots of two Mexican 'snakeweeds', Brongniartia podalyrioides and B. intermedia (Leguminosae). Edunol (3.1 mg/kg, i.p.) reduced the expected… Expand
Prenylflavanols from Tephrosia quercetorum
Abstract The roots of Tephrosia quercetorum afforded three new flavonoids named quercetols A, B and C. Their structures were established by spectroscopic methods, mainly 1 H NMR.
Zoapatle. XII. In vitro effect of kaurenoic acid isolated from Montanoa frutescens and two derivatives upon human spermatozoa.
Zoapatle aqueous crude extract (ZACE) from Montanoa tomentosa has been used as an oral contraceptive in traditional Mexican medicine for centuries. Kaurenoic acid, as isolated from Montanoa… Expand

Two new holostan-type triterpenoid oligoglycosides, named parvimosides A (1) and B (2), were isolated from the warty sea cucumber Stichopus parvimensis (syn. Parastichopus parvimensis). Their… Expand
Oxepane diterpenoids sesquiterpene lactones from ‘zoapatle’ (montanoa tomentosa), a mexican plant with oxytocic activity
Abstract Investigation of the ‘tea’ prepared from the leaves of ‘zoapatle’ ( Montanoa tomentosa ), resulted in the isolation of the known biologically active oxepane diterpenoids zoapatanol and… Expand
Hydroxy-bis-dihydroencelin, a dimeric eudesmanolide and other eudesmanolides from Montanoa speciosa
Abstract Aerial parts of Montanoa speciosa afforded the known eudesmanolides encelin, 1,2-dehydro-3- epi -isotelekin, 1,2-dehydro-3- epi -isotelekin acetate and the eudesmane derivative… Expand
Prenylflavans from Tephrosia watsoniana
Abstract The aerial parts of tephrosia watsoniana afforded five new flavonoids named tephrowatsin A, B, C, D and E. Their structures and stereochemistries were established by spectroscopic methods… Expand
