The authors have previously isolated and purified ursolic acid from heather flowers (Calluna vulgarts). This terpene was found to inhibit HL-60 leukaemic cell proliferation and arachidonic acid oxidative metabolism in various cell species. The effect

In addition to the six diarylnonanoids and diarylnonanoid 3- O -glucosides previously reported from Erica cinerea , the multistep chromatographic processing of the acetone extract of the fresh aerial parts resulted in the isolation of three more repr

In addition to known dibenzofuran derivatives such as (−)-usnic acid, (−)-isousnic acid and (−)-placodiolic acid, a Leprocaulon microscopicum acetone extract yielded a new compound, (±)-9-O-methylplacodiolic acid in a keto-enol equilibrium foc

Continuation of the phytochemical analysis of Erica cinerea fresh aerial parts resulted in the isolation of two new compounds with a very close chromatographic behavior. On the basis of spectroscopic evidence (UV, MS and NMR), the structures were est

Our previous studies have shown that several 7-substituted-4-imidazolylflavans are potent inhibitors of aromatase. These compounds were designed considering the anti-aromatase effect of some natural flavonoids and the importance of an azole ring for

The reinvestigation of Erica cinerea fresh aerial parts led to the isolation of two new diarylnonanoid aglycones along with their glucosides. From spectroscopic data, their structures were elucidated as rel-(3 R ,7 R )-1,9-bis( p -hydroxyphenyl)-3,7-

The lipophile extract of Lonchocarpus nicou roots afforded the new pyranochalcone 3-O-methylabyssinone A as well as the new rotenoids 7′-hydroxytephrosin, and 7′-nor-6′-oxo-2′,3′-dehydrorotenone, both compounds occurring with the known 7′

A lipophile extract of Lonchocarpus nicou roots afforded two likely O -substituted isomers of the known tubaic acids. Spectroscopic analysis assigned to the former, named (−)-rotoic acid, the new 4-(2,3-dihydro-6,7-dimethoxychromon-3-oxy) tubaic ac

Lonchocarpus nicou roots lipophile extract yielded, among isoflavonoids, two coumaronochromones isomers. Spectroscopic analysis assigned the structure of nor-dehydrodeguelin to the former and (−)-nor-dehydrorotenone to the latter, the two products
