A Comprehensive Review on Chemical Profiling of Nelumbo Nucifera: Potential for Drug Development.

Nelumbo nucifera, also known as sacred lotus, has primarily been used as food throughout the Asian continent, and its medicinal values have been described in Ayurvedic and Traditional Chinese Medicine. The purpose of this study is to systematically characterize the chemical profiling and pharmacological activities of N. nucifera. Herein, we critically reviewed and analysed the phytochemical and pharmacological reports of N. nucifera. Our search for the keyword ‘Nelumbo nucifera pharmacology’ in all databases reported in Web of Science yielded 373 results excluding reviews and abstracts in document types. Two hundred and forty‐three spectrum natural compounds from different parts of N. nucifera belonging to diverse chemical groups, including alkaloids, flavonoids, glycosides, terpenoids, steroids, fatty acids, proteins, minerals, and vitamins have been reported. In addition, distinct pharmacological activities, mainly against cancer, microbial infection, diabetes, inflammation, atherosclerosis, and obesity, have been associated with crude extracts, fractions, and isolated compounds. This review highlights potential use of neferine, liensinine, isoliensinine, and nuciferine in clinical trials. In depth, mechanism of the potential chemical entities from N. nucifera via structure activity relationship needs to be explored to guarantee the stability and safety for the clinical use. Copyright

Anti-Obesity Effects of the Mixture of Eriobotrya japonica and Nelumbo nucifera in Adipocytes and High-Fat Diet-Induced Obese Mice.

The present study is to evaluate the anti-obesity effects of Eriobotrya japonica (EJ), Nelumbo nucifera (NN), and their mixture (MIX, 1:1 ratio) in 3T3-L1 adipocytes and high-fat diet-induced obese mice. The treatment of EJ, NN, and MIX in 3T3-L1 adipocytes effectively inhibited lipid accumulation, significantly decreased expression of peroxisome proliferator-activated receptor gamma (PPARγ), sterol regulatory element binding protein (SREBP1c), and adipocyte lipid-binding protein (aP2), and significantly increased phosphorylation of AMP-activated protein kinase (AMPK). Moreover, oral treatment of MIX showed stronger effects than individual treatment. C57BL/6J mice (6 week old) were divided into two groups; low fat diet (LFD) containing 10% calories from fat and high fat diet (HFD) containing 60% calories from fat. The HFD groups were further divided into five subgroups; treated with distilled water (HFD), treated with 400 mg/kg EJ (EJ400), treated with 400 mg/kg NN (NN400), treated with 200 mg/kg MIX (MIX200), and treated with 400 mg/kg MIX (MIX400) during 13 weeks. In our results, the administration of EJ, NN, and MIX significantly decreased body weight (BW), fat weight, liver weight, hepatic triglyceride (TG) and total cholesterol (TC), lipid droplets in the liver, food efficacy ratio, and the plasma TG, TC, glucose, insulin, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels in a dose-dependent manner, and MIX treatment showed stronger effect than their individual treatments. Similarly, MIX treatment decreased the expression of PPARγ, SREBP-1c, FAS, and ACC more strongly in the adipose tissue than single treatments. In conclusion, the MIX of EJ and NN extract may strongly regulate BW gain than EJ or NN alone, and its anti-obesity effect is associated with the control of lipid metabolism, including adipogenesis and lipogenesis.
