Determination of pharmacognostical and bromatological parameters, and evaluation of the antiparasitic activity of a preparation from Bromelia pinguin L. fruits grown in Cuba

Abstract:

Bromelia pinguin L. ("maya" or "mouse pineapple") is a plant broadly distributed in Central America and Caribbean's islands. Its fruit has been used in traditional medicine as anthelmintic. In this work results of pharmacognostical and bromatological study that allowed the establishment of the main yield parameters and quality of the drug fruit of Bromelia pinguin L. are shown, in particular its protein content (3.82 ± 0.31 mg/mL protein), caseinolitic activity (17.06 ± 2.15 Ucas/mL) and sugars content (385.97 ± 76.36 mg/mL). The antihelmintic activity of this partially purified proteolytic preparation of the fruits of Bromelia pinguin L. was tested, with positive results, which also showed activity against Trichomonas vaginalis.
