In spite of the fact that commercial bromelain supplements are available in the market, to date, none of them are produced and formulated from recombinant forms. They are extracted and purified (often partially) from the stem and fruit of pineapple (Ananas comosus). This makes the production of bromelain very difficult, less reliable, often contaminated and expensive. In this study, a recombina...
Fruit bromelain was extracted from the fruit of pineapples. Crude enzyme extract was subjected to heat treatment at 40-80°C for 0-60 min. The temperature stability profiles as a function of different time intervals showed higher retention of enzyme activity at low temperature. Incubation at 40°C showed no loss of fruit bromelain activity up to 60 min, whereas at 50°C almost 83% of activity rema...
There is limited information on the effect of fruits on human cytochrome P450 (CYP) 2C9 activity. The objective of this study was to determine the effect of fruit juice on CYP2C9-mediated drug metabolism. Nine citrus fruits and eight tropical fruits were chosen. We investigated effects of the fruits on diclofenac 4'-hydroxylation and tolbutamide hydroxylation by human liver microsomes. Among th...
BACKGROUND Osteoarthritis (OA) of the knee is the most prevalent joint disorder. Previous studies suggest that bromelain, a pineapple extract, may be a safer alternative/adjunctive treatment for knee OA than current conventional treatment. AIM To assess the efficacy of bromelain in treating OA of the knee. DESIGN Randomized, double-blind placebo-controlled trial. METHODS Subjects (n = 47)...
Pineapple peel is a potential source for the extraction of beneficial bioactive compounds due to the large amount of waste after processing. The extraction of bromelain from pineapple peel by using aqueous two-phase system (ATPs) and its application in muscle models were investigated. Bromelain predominantly partitions to the polyethylene glycol (PEG) rich top phase. The highest enzyme activity...
A total of 140 weanling pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (b.w.) of 6.75 ± 1.48 kg were used in a six-week trial. Pigs were randomly allotted to one of four experimental treatments according to their initial b.w. (seven pens per treatment with five pigs per pen). Dietary treatments were: CON = control diet, T1 = CON + 0.05% bromelain, T2 = CON + 0.10% bromelain, ...
To the Editor Uleerative eolitis is a chronic condition characterized by inflammation of the mucosal layer of the colon. Despite multiple treatments, some patients continue to be symptomatic and seek alternative iherapy. We describe two patients who achieved clinical and endoseopic remission after initiation of bromelain supplementation. A 67-year-old woman with a history of ulcerativc proctiti...
Activation of the TNF-α receptor (TNFR) leads to an inflammatory response, and anti-TNF therapy has been administered to reduce inflammation symptoms and heal mucosal ulcers in inflammatory bowel disease (IBD). Bromelain, a complex natural mixture of proteolytic enzymes, has been shown to exert anti-inflammatory effects. This study aimed to investigate the effect of purified fruit bromelain (PF...
The virulence of enterotoxigenic Escherichia coli (ETEC) is attributed to their ability to adhere via fimbrial adhesins to specific receptors located on the intestinal mucosa. A novel approach to preventing ETEC induced diarrhoea would be to prevent attachment of ETEC to intestine by proteolytically modifying the receptor attachment sites. This study aimed to examine the effect of bromelain, a ...
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...
