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...

Background: Ananas comosus, commonly known as pineapple, is a fruit that is endorsed by the Ministry of Agriculture to be economically important to the island. Tissue culture maybe used as an additional method of propagation to supplement traditional methods to increase productivity. This study was therefore designed to assess the effectiveness of utilising tissue culture techniques to produce ...

Trihelix transcription factors with helix–loop–helix–loop–helix characteristics are essential in plant growth, development, and response to adversity. Several potential functions of have been studied multiple species, but little is known about the features genes pineapple. In this study, 23 members were identified classified into 5 groups unevenly distributed 17 chromosomes The results revealed...

This study assessed and compared different methods for vegetative propagation of a miniature ornamental pineapple hybrid (ORN-MUT), seeking to determine the best method production plantlets, as well removal PMWaV viral complex from plants cultured in vitro, healthy parent plants. Pineapple wilt is disease that can cause large economic caused by called mealybug wilt-associated virus (PMWaV). For...

Bromelain is a mixture of cysteine endopeptidase usually extracted from pineapple juice and used for the treatment various human diseases in industrial applications. demand quickly increasing, its recovery residues appears to be sustainable waste management strategy. Pineapple core among most significant materials production canned richer bromelain than other residues. In this project, we compa...

The main objective of this study was to isolate the fungal strain for enhanced production of xylanase using different agro-residues and fruit peels by solid state fermentation and its potentiality was tested on the pretreated corn cob. Fermentation was carried out with Trichoderma koeningi isolate using untreated and pretreated corn cob supplemented with pineapple peel powder showed higher prod...
