Ten edible fruits of the Sunderbans’ mangrove forest in Bangladesh were analyzed to compare their physicochemical, nutritional and antioxidant properties. Among the fruits, the lowest pH of 4.2 was observed in Sonneratia caseolaris whereas the rest remains within 6.1 to 7.1. The highest electrical conductivity (596.3 μS/cm), total dissolved solid (298.2 ppm) and ash content (0.26%) were recorded in the fruit of Phoenix paludosa. Carbohydrate, protein, lipid and vitamin C contents were the highest in Avicennia officinalis, Ceriops decandra, Heritiera fomes and Bruguiera gymnorrhiza fruits, respectively. In these fruits, the most abundant macro and micro-elements were K and Fe, respectively. C. decandra showed the highest content of polyphenols (58.5 mg GAE, gallic acid equivalent/g powder), flavonoids (86.4 mg CE, (+)-catechin equivalent/g powder) and anthocyanins (0.39 μmol/g powder). C. decandra also showed the strongest DPPH free radicals scavenging, reducing power, and total antioxidant capacity. Noticeably, total polyphenols showed their strong correlation to total flavonoids (r2 = 0.90), anthocyanins (r2 = 0.81), reducing power (r2 = 0.98) and total antioxidant capacity (r2 = 0.88) of the fruits. Fruits of C. decandra, therefore, should be considered as a potential source of antioxidants followed by H. fomes and P. paludosa.
This study evaluated anti-bacterial, anti-diarrheal, and cytotoxic activities of ten edible fruits (Aegiceras corniculatum, Avicennia officinalis, Bruguiera gymnorrhiza, Ceriops decandra, Heritiera fomes, Nypa fruticans, Phoenix paludosa, Sarcolobus globosus, Sonneratia caseolaris, and Xylocarpus mekongensis) in the Sundarbans mangrove forest of Bangladesh. Highest antibacterial activity was shown for ethanol : methanol (1:1) extracts of S. caseolaris (2 mg/disc), which demonstrated inhibition zones of 16.7, 17.0, 14.7, 15.7, and 15.7 mm against Escherichia coli, Klebsiella sp., Shigella boydii, Shigella sonnei, and Staphylococcus aureus, respectively. In mice with castor oil-induced diarrhea, S. caseolaris extract (250 mg/kg body weight) showed the highest inhibition (87.7%) and delayed the onset time (273 min) of diarrheal episodes, followed by A. corniculatum extract (inhibition, 83.6%; delayed onset time, 187.4 min). S. caseolaris and A. corniculatum fruit powders were successively fractionated into n-hexane, diethyl ether, chloroform, ethanol, and methanol. Antidiarrheal activity significantly increased with increasing polarity of these fractions. In brine shrimp lethality assay, S. globosus extract demonstrated the highest cytotoxicity (59.2 μg/mL), followed by H. fomes (74.1 μg/mL) and C. decandra (116.7 μg/mL); however, lowest cytotoxicity was shown for A. corniculatum, A. officinalis, and S. caseolaris extracts. Mice treated with A. corniculatum extract did not experience any acute toxicity. These results demonstrate that S. caseolaris and A. corniculatum fruits have potential to treat diarrhea and may act as useful nutraceuticals.
A comparison of total polyphenols (TP) and flavonoids (TF) contents, antioxidant activity, and silver nanoparticles (AgNPs) biosynthesis potentiality of 35 common edible fruits in Bangladesh were studied. Among the fruits, Emblica officinalis showed the highest content of TP (89 mg gallic acid equivalent (GAE)/g powder), reducing power (OD, 1.98 at 1 mg powder/ml), and 2,2-diphenyl-1-picrylhydrazyl (DPPH)-free radical scavenging activity (95.6% at 0.5 mg powder/ml) whereas the highest content (17.3 mg (+)-catechin equivalent (CE)/g powder) of TF was recorded in Garcinia cowa. The inhibitory concentration 50 (IC50) for DPPH-free radical scavenging of Annona reticulata, E. officinalis, G. cowa, Phoenix sylvestris, Psidium guajava and Syzygium cumini were 180, 21.8, 172, 188.9, 162.4 and 176.2 μg powder/ml, respectively. Litchi chinensis showed the highest total antioxidant capacity (79 mg GAE/g powder) followed by E. officinalis (69 mg GAE/g powder). The fruits showed a very strong correlation (r2 = 0.99) between TP and reducing power. P. guajava showed the highest potentiality (OD, 0.74 at 10 mg powder/ml) in the biosynthesis of AgNPs followed by S. cumini, A. reticulata and P. sylvestris. Therefore, most potential five fruits should be graded as E. officinalis > S. cumini > P. guajava > A. reticulata > P. sylvestris. Bangladesh J. Bot. 50(3): 445-451, 2021 (September)
One hundred and forty six inbred lines CIMMYT maize were characterized based on some morphological traits and grain yield at the experimental field of Bangladesh Agricultural Research Institute (BARI) during 2009-10 to study the maintenance and characterization of new exotic maize inbreeds. Maximum variation was found in number of grains per row, number of cobs per row, grain yield/plant, cob length (cm), ear height (cm) and plant height (cm). On the basis of D2 analysis, 146 inbred lines were grouped into 6 clusters. The inter cluster D2 values varied from 0.974 to 6.595 which exhibited medium range of diversity present in the inbred lines. It is expected that crossing of inbred lines belonging high to medium D2 values tend to produce high heterosis for yield. Development of hybrids utilizing these genotypes has the chance to obtain higher heterosis with high performing crosses. In order to achieve more heterotic partners from 146 CIMMYT (India) inbreeds were characterized for their morphological traits and kernel yield. Selfed seeds for each of the inbreeds line also maintained for future breeding works. Development of hybrids utilizing these genotypes has the chance to obtain higher heterosis with high performing crosses.
Experiment was conducted on six varieties including two advanced line growing in large scale in Bangladesh. These varieties were evolved by BARI and work was conducted for evaluation of physicochemical parameters of the rapeseed and mustard. Among these varieties, the highest grain weight was obtained from BARI Sarisha-9 (4.9g) and lowest grain weight obtained from BARI Sarisha-15 (2.9g).The variety BARI Sarisha-15 was contained highest amount of moisture (9.55%) while lowest amount was found advanced line Din-2 (5.78%). Among all the treatments, highest dry matter contained was showed by Din-2 (94.22%) and lowest amount showed by BARI Sarisha-15 (90.55%). Highest amount of oil cake was given by BARI Sarisha-12 (59.95%) and lowest amount gave by BARI Sarisha-14 (57.75%). BARI Sarisha-14 possessed the highest amount of β-carotene (23.56µg) and lowest amount was observed by BARI Sarisha-9 (4.19µg). BARI Sarisha-14 possessed the lowest dry wt. of oil cake (49.70%) and highest dry wt. of oil cake was observed by BC-2193 (53.03%). The highest amount of saponification value was recorded by BARI Sarisha-14 (168.3) and lowest amount was recorded by BC-2193 (154.6).The highest amount of iodine value was recorded by BARI Sarisha-14 (110.2) and lowest amount was recorded by Din-2 (93.45). The highest amount of acid value was recorded by BARI Sarisha-14 (1.61) and lowest amount was recorded by BC-2193 (1.31).
