“…In addition it is reported that the polyphenolic as well as flavonoids content in the ethanolic extract is greater than that in the aqueous extract explaining its greater antioxidant influence, yet, according to the HPLC analysis the superior content of flavonoids (2.8 times ) particularly quercetin and kaempferol in addition the polyphenolic content (1.6 times) in the ethanolic extract as compared to the aqueous extract explains the reported antioxidant effect. Thus, the magnitude of the antioxidant influence is attributed to the quantity and quality of the polyphenolic compounds in particular kaempferol and quercetin [270] .…”

Aquatic plants are versatile source of phytochemicals that are of significant biological influences particularly, the flavonoids and their glycosidic derivatives distributed in different plant parts including fruits, seeds, leaves, flowers, stem, roots and rhizomes. Most of the reported biological influences are reported to be expressed by quercetin, kaempferol, isorhmnatin, and their glycosidic derivatives, particularly, rutin. In this survey, we summarized the reported flavonoids types, content and factors affecting their extracts contents of three aquatic plants Nuphar, Najas and Nymphoides detected in the Iraqi central marshlands, in provenance of Thi-Qar. Surveying the phytochemical investigations regarding Nuphar species of reported abundance of polyphenolic compounds content including identified and quantified phenolic acids, flavonoids like flavonols and flavonones, particularly, in their leaves. However, flavonoids/their derivatives types and quantities in various parts extracts are not reported to the extent of our knowledge although they are presumed to contribute to the reported biological influence of the plant on one hand. On the other hands, regarding Najas species, few reports have identified the existence of flavonoids as well as other phenolic compounds, although, total quantification to the phenolic compounds, flavonoids and tannins are reported rather than identifying the individual flavonoid in the plant extracts. Only single report demonstrates the total phenolic, flavonoids and tannin contents of ethyl acetate extract of Najar minor according to our survey. Regarding Nymphoides species, the extraction level flavonoids as lipophilic compounds as well as their much polar glycosidic derivatives is depending on the solvent polarities. In general, in most of Nymphoides species the ethanolic extract querectin, methylquercetin and kaempferol flvonoides/their derivatives are identified individual flavonoids/quantified to be more than one fold of that in the aqueous extracts. Finally, the manner/position of glycosylation as well as glycosides sugar resides acylation vary among the Nymphoides species. In general, single 3-O- or di 3,4’-O- glycosylation pattern is noticed in kaempferol, quercetin and isorhamnetin. The multiply diverse glycosylation, methylation as well as acylation pattern of Nymphoides species flavonoids may explains their identification in various plant part/extracts besides the variation in their biological activities potentials.

Nymphoides hydrophylla (NH) is mainly an aquatic herb of Menynthaceae family and traditionally used to treat fever, insect bites, different ulcers, and also to wash skin, where parasitic affection occurs. In this study, methanolic extract of Nymphoides hydrophylla (NH) plant was examined for the determination of thrombolytic, antipyretic, Central Nervous System (CNS) and analgesic activities. The evaluation of thrombolytic potential, antipyretic, CNS and analgesic activities of the plant extract occurred by their clot lysis, temperature reducing, and depression-inducing and pain sensation decreasing ability respectively. The result from the study showed the thrombolytic activity 3.05 ± 0.70% to 26.45 ± 2.18% indicating the better thrombolytic activity at a lower dose. The maximum pyrexia suppression of 91.07% is observed for 400 mg/kg NH extract. In hole cross and open field tests, maximum 71.42% and 66.80% suppression of locomotor activity were observed with the methanolic NH extract (400 mg/kg) whereas suppression of the locomotor activity of the standard drug diazepam was 68.57% and 51.20% respectively. From the analgesic data, about 91.72% inhibition was observed for 400 mg/kg of NH extract. Statistical calculation was carried out by using one-way ANOVA followed by Dennett's multiple comparisons tests, where statistically significant values from control *P<0.05, **P<0.01, ***P<0.001. Finally, this investigation indicates that due to having a potent bioactive compound in case of CNS disorder and pain sensation, N. hydrophylla could be a natural alternative medication of depressant and analgesic agent. INTRODUCTION: Human and plants are inalienable parts of nature. This is assumed that in the health care of every individual and community, medicinal plants have greater importance, although about 4000 million people of the world are entirely dependent on herbal medicine till today.
