Bitter gourd (Momordica charantia) were analyzed for their major nutrient contents as well as Vitamin C, minerals and phytochemical constituents. The selected varieties were Charantia C.B. Clarke, Muricata (Willd.), Hybrid green and Hybrid white karala. The result revealed the presence of nutrient constituent among the varieties comprising Total sugar (0.114±0.01% to 0.22±0.02%), Starch (0.74±0.01% to 5.3±0.04%), Total protein (1.17±0.01% to 2.4±0.02%), Fat (0.3±0.02 to 0.8±0.02%) and Vitamin C (9.41±0.26 to 13±0.57mg%). This vegetable is good source of minerals such as Mg, Ca, S and Cu. The fruits contained calcium (0.55±0.30 to 7.0±0.25 mg%) and sulpher (44.9±0.38 to 72.4±0.51 ppm). All the varieties were found to contain tannin, flavonoids, terpenoids, cardiac glycosides, triterpin and sterol, resin, amino acid and phenolic compounds except coumarin and free anthraquinone. Based on the findings from this study, bitter gourd (Momordica charantia), although a bitter known vegetables but has enormous nutritional potentials. |

Although strawberry is produced mainly in the cold weather but recently it
is a newly introduced crop in the subtropical country like Bangladesh by tissue
culture technique. It is not only the excellent sources of Vitamin C, β-Carotene,
dietary fiber and some other nutrients but it has also several medicinal importances
for human health and nutrition as reported by researchers in different countries
other than Bangladesh. The major nutrient contents as well as minerals and vitamins
of two varieties, Varaity-1 (Long Conic) and Variety-2 (Globose Conic) of strawberries
were analyzed. The result revealed the presence of nutrient constituent among
the two varieties, Varaity-1 (Long Conic) and Variety-2 (Globose Conic) of strawberries
comprising Total sugar (3.15±0.01 and 2.5±0.02%), Reducing sugar
(0.0335±0.01 and 0.048±0.01%), Non-reducing sugar (3.12±0.01
and 2.4±0.01%), Starch (0.395±0.02 and 0.685±0.04%), Water
soluble protein (0.785±0.01 and 0.986±0.01%), Total protein (1.2±0.02
and 1.5±0.02%), fat (0.4±0.01 and 0.6±0.02%), Vitamin C
(116±0.32 and 179±0.52 mg%), Beta-carotene (3.71±0.25 and
4.15±0.30 μgm%) and minerals such as Magnesium (17.35±0.01
and 17.76±0.01 mg%), Calcium (6.40±0.20 and 11.36±0.40
mg%), Potassium (38.00±0.20 and 43.00±0.01 mg%), Copper (0.1365±0.02
and 0.0275±0.01 mg%), Iron (0.12±0.02 and 0.5415±0.01 mg%),
Zinc (0.092±0.01 and 0.049±0.03 mg%), Phosphorous (0.718±0.01
and 0.627±0.02 mg%) and Sulphur (5.56±0.20 and 5.735±0.22
mg%), respectively. Results of present study suggest that Strawberry is a good
source of sugar, anti-oxidants and minerals and among both the varieties, Variety-2
(Globose Conic) is rich of sugar, total protein, water soluble protein, Vitamin
C, Beta-carotene, Magnesium, Calcium, Potassium, Iron and Sulphar. In this study,
the aqueous extract of two varieties (Long Conic and Globose Conic) of strawberry
was tested for anti-microbial activity by disc diffusion method and cytotoxicity
by brine shrimp nauplii. From the results, it was found that the aqueous extract
of both varieties of strawberry revealed anti-microbial activity against gram
positive and gram negative bacteria. It was also found that the aqueous extract
of two varieties of strawberry was not shown cytotoxic activity. Even though,
the aqueous extract of two varieties of strawberry was not shown toxicity on
brine shrimp nauplii but they are showing anti-bacterial activity against gram
positive and gram negative bacteria. This result clearly indicates the presence
of potent bioactive principles in this aqueous extract of both varieties of
strawberry which suggests a need to isolate, purify and evaluate active constituents
responsible for this anti-microbial activity. |
