Hypocholesterolaemic and hypoglycaemic efect of banana blossom were studied in high-cholesterol fed rats. Experimental groups
were fed for 4 weeks, with casein as the basal diet (CN), in comparison with two diets containing 0.5% cholesterol (CD) and
0.5% cholesterol + 21% banana blossom powder (CDB). Serum total cholesterol, non-HDL-cholesterol level, and serum glucose
concentrations were lower in CDB fed group compared with CD fed group. Lower serum cholesterol and glucose level ( < 0.05)
in CDB fed group were followed by higher faecal weight, caecal weight, caecal Lactobacilli, and Bifdobacteria population in CDB
fed group compared to CD diet fed group. Lower serum AST level in banana blossom fed rats showed the reduction in oxidative
stress induced by high cholesterol diet. Based on these data, it could be speculated that banana blossom incorporated experimental
diets may modulate the hypocholesterolaemic and hypoglycaemic responses in Wistar rats.
1. Introduction
Blossom of the banana plant (Musa acuminata Colla), by-
product of banana cultivation, is ofen consumed as a veg-
etable in many Asian countries such as Sri Lanka, Malaysia,
Indonesia, and the Philippines [1]. In Sri Lanka, it is con-
sumed as a curry as well as a boiled or deep fried salad with
rice and wheat bread [2]. Banana blossoms have tremendous
nutritional value and are rich source of dietary fbre and
some biologically active compounds like vitamin C, tannin,
myoinositol phosphates, and alpha tocopherol [3–5]. High
levels of dietary fbre intake are associated with signifcantly
lower prevalence rates for coronary heart disease, stroke,
and peripheral vascular disease [6–8]. However, average fbre
intakes for children and adults are alarmingly less than
that of the recommended level [9]. Food components with
antioxidant properties may prevent cardiovascular diseases
by inhibiting the oxidative damage to LDL-cholesterol [10].
Recently, polyphenols have been found to afect blood lipids
in animals in a similar manner as soluble dietary fbre [11].
In another study, chloroform, water, and ethanol extract of
another banana variety (Musa sapientum) fowers were found
to exhibit hypoglycaemic activity in alloxan diabetic rat [12–
14]. Hemicellulose fraction of Musa sapientum showed high
amounts of total polyphenols and total antioxidants [15],
indicating that banana blossom is a rich source of dietary fbre
associated with polyphenols, which could promote health
benefts. As the dietary fbre consumption is alarmingly low,
it is important to investigate the potential of underutilized
vegetables as potent antioxidants and blood lipid lowering
agents. Tough banana blossom has been in the Sri Lankan
diet for years, no research has been done to investigate the
health potential of banana blossoms as a fbre and antioxidant
rich vegetable. Tus, the aim of this study was to investigate
the banana blossom incorporated experimental diets on
blood lipids and blood glucose level in rats fed cholesterol.
