PARTE UTILIZADA= Used part: Hojas.

ACCIÓN FARMACOLÓGICA= Pharmacological action: Antihelmíntico.

COMPOSICIÓN QUÍMICA= Chemical composition: The major and minor carotenoids fruits, buriti (Mauritia vinifera), mamey (Mammea americana), marimari (Geoffroea striata), peach palm (Bactris gasipaes), physalis (Physalis angulata), and tucuma (Astrocaryum aculeatum), all native to the Amazonia region, were detd. by HPLC-photodiode array detector-mass spectrometry detector (HPLC-PDA-MS/MS), fulfilling the recommended criteria for identification. A total of 60 different carotenoids were sepd. on a C30 column, all-trans-beta-carotene being the major carotenoid found in all fruits. The presence of apo-10'-beta-carotenol, found in mamey, was not previously reported in foods. In addn., this is the first time that the identification of beta-zeacarotene in natural sources is supported by MS data. The total carotenoid content ranged from 38 ug/g in marimari to 514 ug/g in buriti. All fruits analyzed can be considered good sources of provitamin A, esp. buriti, with 7280 RE/100 g.

ZONA GEOGRÁFICA= Geografical zone: desde Ecuador hasta NE de Argentina.
