Ipomoea reptans Poir or kangkung is a popular leafy vegetable, a favorite to people in Asian countries. However, limited information is available on their bioactivities. In the present study, the antioxidant, antidiabetic, and anti-obesity potential of I. reptans leaves were investigated. Different fractions (ethanol, ethyl acetate, and hexane) of I. reptans leaves were evaluated for their scavenging activity on DPPH radicals, whereas their reducing potential was investigated by cupric reducing antioxidant capacity (CuPRAC), total antioxidant, and reducing power assays. The antidiabetic potential was investigated by their inhibition effect on a-glucosidase. Total phenolic and flavonoid contents of I. reptans leaves were solvent dependent. Ethyl acetate contained the highest phenolic content, followed by ethanol and hexane fractions. However, for flavonoid content, the order was ethanol > ethyl acetate > hexane. All fractions showed DPPH scavenging activity in a concentration-dependent manner, with activities weaker than standards ascorbic acid and BHT, in the order of ethanol > ethyl acetate > hexane. All fractions showed reducing capacity, but only hexane and ethanol fractions of I. reptans leaves showed inhibition on a-glucosidase, with hexane showed more potent inhibition compared to acarbose. The study also found that fractions of I. reptans inhibit lipase and trypsin, enzymes related to lipid metabolism. Findings in this study offer a prospect for I. reptans leaves as a functional food source for antioxidant, antidiabetic, and anti-obesity purposes.

“…The primary hazard of cigarette smoking (either voluntarily or involuntarily) is oxidative stress, and it is suggested that reactive oxygen species (ROS) in the smoke is the culprit. , ROS in smoke includes peroxyl radicals, carbon-centered radicals, and nitric dioxides . Evidence has shown that ROS can damage DNA, initiate lipid peroxidation, and cause inflammation.…”

Fluorescent Approach to Quantitation of Reactive Oxygen Species in Mainstream Cigarette Smoke

A novel approach to monitoring of mainstream smoke reactive oxygen species (ROS) has been developed and applied to the quantitation of smoke oxidants. Redox-active fluorescent probe dihydrorhodamine 6G (DHR-6G) was selected as the molecular probe because it is sensitive to typical smoke ROS. The experimental system couples an automatic cigarette smoke machine fiber-optic fluorometer for real-time monitoring of the reaction progress between cigarette smoke and DHR-6G. Quantitation was achieved based on the amount of rhodamine 6G, which is the sole product from DHR-6G oxidation. With the optimization of the trapping efficiency, we detected 391 nmol of ROS/cigarette in the mainstream CS for a standard cigarette 2R4F under standard Federal Trade Commission smoking protocol. Applying this method, we quantified the ROS of selected cigarettes and found that the cigarettes made of burley tobacco have much ( approximately 10 times) higher ROS content in the smoke than that in the tobacco made of bright tobacco. The smokeless cigarette, Eclipse, has comparable ROS with cigarettes made of bright tobacco.
