Nelumbo nucifera herb, seeds, plant, extract

Nelumbo nucifera Gaertn. (Nymphaceae) has been used for various medicinal purposes by Chinese herbalists. Flavonoids in the leaves of Nelumbo nucifera Gaertn (lotus leaves) have many pharmacological activities. Some of these flavonoids include hyperin, isoquercetin and astragalin.

The effects of embryos of the seeds of Nelumbo nucifera on the central nervous system were studied in mice. MeOH extracts of embryos of Nelumbo nucifera seeds significantly inhibited locomotor activity in mice. Our results suggest that neferine has several central effects and that neferine may participate in the efficacy of the sedative effects of embryos of the seeds of Nelumbo nucifera. The mechanisms of the sedative effects of neferine are not similar to those of diazepam.

To further investigate the relaxation mechanism of neferine, a bis-benzylisoquinoline alkaloid extracted (isolated) from the green seed embryo of Nelumbo nucifera Gaertn in China, on rabbit corpus cavernosum tissue in vitro. Neferine from Nelumbo nucifera, with its relaxation mechanism, can enhance the concentration of cAMP in rabbit corpus cavernosum tissue, probably by inhibiting phosphodiesterase activity.

Nelumbo nucifera leaves are known for diuretic and astringent properties, and are used to treat obesity. During our search for a plant-derived anti-obesity agent from natural products, we have found that a 50% ethanol extract prepared from the leaves of Nelumbo nucifera stimulated lipolysis in the white adipose tissue of mice and that the beta-adrenergic receptor pathway was involved. In subsequent experiments, dietary supplementation of Nelumbo nucifera resulted in a significant suppression of body weight gain in A/J mice fed a high-fat diet. Our results indicate that the effects of Nelumbo nucifera in preventing diet-induced obesity appear to be due to various flavonoids and that the activation of beta-AR pathway was involved, at least in part.
