Sacred lotus (Nelumbo nucifera Gaertn.; N. nucifera) is a common ingredient in traditional medicine and Thai recipes. Its petal is an agricultural waste from stamen production. There are limitations in the used and pharmacological data of the petals resulting in more petals waste. The aims of this study were to investigate the phytochemical contents, antioxidant activity, and potential effects on sperm viability of aqueous (NAE) and ethanolic extracts (NEE) of both red and white N. nucifera petals. The white NAE had the highest total phenolics content, total tannins content and maximal antioxidant activity. The white NEE had the highest concentration of total flavonoids. Quercetin was a major flavonoid and was found in the aqueous extracts. Both red and white of NAE in the range of 0.22 to 1.76 mg/mL increased sperm viability. The white NAE was prominent in phytochemical content, antioxidant activity, and both red and white NAE effectively increased rat sperm viability in the in vitro model. The white NAE enhanced sperm viability by decreasing oxidative stress. It might be suggested that the N. nucifera petals have benefits for sperm viability health promotion and may increase the economic value of agricultural waste.

AbstractSacred lotus (Nelumbo nucifera, or lotus) is one of the most widely grown aquatic plant species with important uses, such as in water gardening and in vegetable and herbal medicine. A public genomic database of lotus would facilitate studies of lotus and other aquatic plant species. Here, we constructed an integrative database: the Nelumbo Genome Database (NGD, http://nelumbo.biocloud.net). This database is a collection of the most updated lotus genome assembly and contains information on both gene expression in different tissues and coexpression networks. In the NGD, we also integrated genetic variants and key traits from our 62 newly sequenced lotus cultivars and 26 previously reported cultivars, which are valuable for lotus germplasm studies. As applications including BLAST, BLAT, Primer, Annotation Search, Variant and Trait Search are deployed, users can perform sequence analyses and gene searches via the NGD. Overall, the valuable genomic resources provided in the NGD will facilitate future studies on population genetics and molecular breeding of lotus.

The phytochemicals of the ethanolic extracts of petals and stamens of lotus flowers from several lotus cultivars belonging to the Nelumbo nucifera Gaertn. (namely 'lotus white flower' and 'lotus pink flower') were studied by color reaction test and HPTLC analysis. The lotus pink flower stamens showed a highest amount of ethanolic extractives (ca. 18.33±2.14% of dry material weight). The several the ethanolic extracts of N. nucifera petals and stamens showed similar qualitative phytochemicals. The crude extracts revealed the presence of flavonoids, terpenoinds, tannins and polyphenols. The antioxidant activity was assessed using the 2,2-diphenyl-1-picrylhydrazyl assay. The analyzed lotus pink flower stamens ethanolic extract showed a highest antioxidant activity at IC50 = 0.61±0.16 μg/ml and lotus pink flower petals ethanolic extract showed a highest tyrosinase inhibitory effect at IC50 = 2.25±0.21 μg/ml. N. nucifera flowers could be provide a potential natural source of phytochemicals and could be beneficial to the cosmetic properties.

Objective: The main objective of the study was to investigate the effect of ethanol seed extracts of Nelumbo nucifera Gaertn (Nymphaeaceae) as antihyperglycemic, anti-hyperlipidemic and antioxidant activity in streptozotocin-induced diabetic rats.Methods: Diabetes was induced in wistar albino rats by administration of streptozotocin (single intraperitoneal dose of 60 mg/kg B. W). The ethanol extract of N. nucifera seed at a dose of 200 and 400 mg/kg body weight was administrated at a single dose per day to STZ induced diabetic rats for a period of 42 d. The different pharmacological parameters were evaluated. The effect of ethanol seed extract of N. nucifera on insulin, blood glucose, urea, creatinine, HbA1C, serum protein, albumin, globulin, serum enzymes, serum lipid profiles, lipid peroxides (LPO) and other antioxidant enzymes like catalase (CAT), glutathione peroxidase (GPx), superoxide dismutase (SOD) and reduced glutathione (GSH) were measured in the diabetic rats.Results: In the acute toxicity study ethanol seed extract of Nelumbo nucifera were non-toxic at 2000 mg/kg in rats. The ethanol extract of Nelumbo nucifera seed showed significant reduction in blood glucose (p<0.05), serum enzymes (SGPT, SGOT, ALP) (p<0.05), lipid parameters (TC, TG, VLDL, LDL) (p<0.05) except HDL and significantly increased insulin (p<0.05), HDL (p<0.05), GPx, GSH, SOD and CAT (p<0.05) at the dose of 400 mg/kg when compared with the diabetic-induced control.Conclusion: The present study suggested that the NNSE has significant (p<0.05) antihyperglycemic, antihyperlipidemic and antioxidant activity in STZ induced diabetic rats. These results clearly indicate that Nelumbo nucifera is effective against free radical-mediated diseases, thus replacing the synthetic ones.
