Cinnamic, p-coumaric and ferulic acids were isolated from pineapple stems (Ananas comosus var. Cayenne). Twenty-four kinds of esters were prepared from these acids, alcohols and the components of Alpinia. Isopropyl 4-hydroxycinnamate (11) and butyl 4-hydroxycinnamate (12) were found to have almost the same effectiveness in antifungal activity against Pythium sp. at 10 ppm as that of the commerc...

Bromelain is a crude extract from the fruit or stem of pineapple [Ananas comosus (Linn.) Merr.] plant. It consists of different closely related proteinases which are good antiinflammatory, antithrombotic and fibrinolytic agents. The active fractions have been characterized biochemically and found to be effective after oral administration. It has earned universal acceptability as a phytotherapeu...

The structure of a recombinant pineapple cystatin (AcCYS) was determined by NMR with the RMSD of backbone and heavy atoms of twenty lowest energy structures of 0.56 and 1.11 Å, respectively. It reveals an unstructured N-terminal extension and a compact inhibitory domain comprising a four-stranded antiparallel β-sheet wrapped around a central α-helix. The three structural motifs (G(45), Q(89)XVX...

Although, several pineapple micropropagation protocols have already been published, significant improvement could be achieved, if the stages of in vitro culture were better defined. Our work concerned several experiments aiming at the mass production of high quality plantlets. Tissue culture experiments were therefore conducted to develop rapid multiplication procedures for Ananas comosus L. (M...

Background Bromelain is a collective name for proteolytic enzymes or proteases (natural proteolytic enzymatic complex) found in tissues including stems, fruit and leaves of the pineapple (Ananas comosus var. comosus) and of other plant species of the family Bromeliaceae [1]. Is a bioactive agent possessing remarkable therapeutic properties such as reversible inhibition of platelet aggregation, ...
