also known as water spinach, is an aquatic non-conventional leafy vegetable and is considered a healthy and seasonal delicacy in ethnic food culture. The study revealed the presence of rich chemical ...and biochemical composition in
and antioxidant activities. Moreover, the plant extracts demonstrated significant DNA damage prevention activity against UV/H
O
-induced oxidative damage. High-resolution mass spectrometric analysis by UPLC-qTOF-MS/MS resulted in the identification of over 65 different compounds and 36 important secondary metabolites. Most of the compounds identified represented polyphenolic compounds,
polyphenol glycosides and phenolic acids, followed by alkaloids and terpenoids. A UPLC-DAD method was developed and quantified for 10 different polyphenolic compounds. Out of all the metabolites examined, a significant number of compounds were reported to have various bioactive properties, including antibacterial, antiviral, antitumor, hepatoprotection, and anti-depressant effects. The plant extracts were found to contain various compounds, including euphornin, lucidenic acid, and myricitin glycosides, which possess significant medicinal value. Metabolite analysis utilizing GC-MS revealed the presence of various fatty acids, amino acids, sugars, and organic acids. The analysis revealed the presence of essential unsaturated fatty acids such as α-linolenic acid as well as beneficial substances such as squalene., The evaluation of glycemic control activity was carried out by comprehending the inhibitory potential of α-amylase and α-glucosidase, outlining the kinetics of the inhibition process. The inhibitory activities were compared to those of acarbose and revealed stronger inhibition of α-glucosidase as compared to α-amylase. Furthermore, the mechanism of inhibition was determined using
analysis, which involved molecular docking and molecular dynamic simulation of the identified IA phytochemicals complexed with the hydrolase enzymes. The study generates convincing evidence that dietary intake of
provides a positive influence on glycemic control along with various health-protective and health-promoting benefits.
Pollution is the unavoidable evil of the present-day civilization and the genesis of the problem of pollution is synonymous with the advent and spread of science and technology based industrial ...civilization. Unlike the problem of natural calamities, pollution is mainly anthropogenic i.e. due to diverse human activities, industrialization, urbanization, modem agricultural practices and consumers life style; which are integral part of present day civilization. The problem of pollution has become aggravated due to lack of adequate control by man over his activities and products he makes. Since the dawn of civilization always progress is in forward direction. It is logical to infer that in general there is no scope for abatement of pollution, rather there is a growing apprehension that in the 21st century and beyond; pollution will assume alarming proportion if the present trend continues as such. Pollution is mainly anthropogenic but it affects the entire biosphere and overall global environment. Thus all other life forms suffer from it, although they are not responsible for pollution. The very fact that under the auspices of United Nations since 1980s a number of summit meetings on environmental pollution have been held in Rio-De-Janerio, Montreal, Cairo etc. indicate the gravity of the problem. After decades of suffering the entire international community has recognized pollution as a serious problem for the mankind and planet earth and has rightly accorded top priority to it. Apart from political initiative, science and technology has to play a pivotal role in combating and controlling pollution. Because, since the last century science and technology has been playing the most dominant role in solving most problems facing by the society. The role of scientific research in tackling pollution is thus self-explanatory. Since time immemorial human activities have always generated wastes. But in older days they were far and few and they easily got dispersed, diluted and degraded by nature and hence waste generation never created a problem.
The seasonal life cycle and biology of a white grub beetle, Lepidiota mansueta Burmeister (Coleoptera: Scarabaeidae), were studied on Majuli river island and in the laboratory during 2005â2010. ...This species has become an extremely serious pest of many field crops on Majuli river island, the largest mid-river deltaic island of the world. L. mansueta has a biennial life cycle, the first of its kind in North East India, and the duration of egg, grub, and pupal stages varied from 12 to 17, 635 to 671, and 28 to 35 days, respectively. Third instar grubs as heavy as 6 g caused heavy damage to crops and had a prolonged developmental period ranging from 545 to 563 days in the laboratory (27 °C). L. mansueta can be regarded as a rare species, because it spends its entire life cycle under the ground except for a short period during which adults emerge from the ground for mating. There was no evidence that the adults fed on plants either in the field or in the laboratory and hence this species has the unique distinction of being the first Indian phytophagous white grub species with nonfeeding adults.
