The genus Nymphoides is a freshwater aquatic dicot represented by two species in Iran. Based on our current regional taxonomic revision of this genus, we recognize Nymphoides cristata, previously identified as Nymphoides indica in Flora Iranica. However, these species are easily distinguished from each other by having crested petal lobes in the latter. We investigated the morphology and anatomy of Nymphoides cristata and Nymphoides peltata. The most important morphological features for differentiation between these species are corolla color and inflorescence type. The anatomy of cross-sections of leaf, petiole, stem and the surface sections of leaf were studied. The following characters were found to be taxonomically informative: the presence of stellate, polyramous and ramiform foliar sclereids as well as the presence of astrosclereids in petioles and stems of both examined taxa, while spheroidal sclereids are only observed in the stems of Nymphoides peltata.

Nymphoides Indica

Nymphoides indica, an aquatic plant, is used as folk medicine in some countries. Our previous study demonstrated that the methanol extract of N. indica inhibited the activity of tyrosinases, tyrosine related protein (TRP)1 and TRP2, and microphthalmia-associated transcription factor, as well as the activity of protein kinase A, by effectively inhibiting cyclic adenosine monophosphate. Although the biological activities of N. indica extract have been reported, there are no reports on the skin bioactivity of the main compound(s) on human keratinocytes. This study investigated the anti-inflammatory and moisturizing effects of quercetin 3,7-dimethyl ether 4′-glucoside (QDG) isolated from N. indica. In brief, ultraviolet B irradiated keratinocytes were pretreated with different concentrations of QDG, and the effects of QDG on various inflammatory markers were determined. QDG significantly inhibited inflammation-related cytokines and chemokines and enhanced the activation of skin barrier factors. Additionally, QDG also attenuated phosphorylation inhibition of the upstream cytokines and nuclear factor-κB expression. These results suggest that QDG isolated from N. indica may serve as a potential source of bioactive substances for chronic inflammatory skin diseases.

Nymphoides Indica

The aim of the study was to perform comprehensive phytochemical analysis, UHPLC, ATR-FTIR profiling and evaluation of various biological activities of N. Indica rhizome. The phytochemical analysis indicated presence of alkaloids, saponins, and triterpenes. In the antioxidant assay, the methanolic (IC50 40.3±0.04) and chloroform fractions (IC50 40.05±0.21) showed highest DPPH inhition. Like wise, methanolic fraction showed highest FRAP value (756.2±0.06) followed by chloroform (225.0±0.04) and ethyl acetate fractions (193.0±0.21). In the antimicrobial assays, chloroform (MIC <  0.156 mg/ml) and methanol fractions (MIC 0.625 mg/ml) fractions showed significant inhibition of Klebsiella pneumoniae. Also a significant antibiofilm of biofilm formation was recorded by chloroform (IC50 1.73 mg/ml) and ethyl acetate fractions (IC50 1.76 mg/ml). It was concluded that the N. Indica rhizome posess antioxidant, antimicrobial and antibiofilm potential, that may be attributed to high flavonoid contents.

The lake trapping was continued twice monthly from February 1991, two years after the first filling of the stage 2A reservoir, until June 1993. The trapping locality at Toonpan was essentially the same as for the 1984–85 studies except that for Big Bay was moved a few hundred metres up the incline. Because the expansion from stage 1 to 2A involved extensive clearing of marginal scrub, grassland and forest, almost total control of five mosquito species utilizing tree holes and plant axils (Aedes alboscutellaris, Aedes mallochi, Aedes purpureus, Aedes quasirubithorax) or shaded pools (Uranotaenia nivipes) occurred. The transformation of temporary wetland with ti-trees (Melaleuca spp.), lilies (Nymphoides indica, Nymphaea gigantea) and submerged plants into an unvegetated muddy foreshore similarly reduced Mansonia spp. and Coquillettidia crassipes, whose larvae depend on attachment to arenchymatous or lacunate macrophytes. Larvae of these genera have pointed reinforced tips to their siphons which are used to pierce these plants to breathe. Because of the devastating nature of the inundation and the time required for new breeding habitat to re-establish, mosquito populations increased through to the end of 1993 but the mean abundance of adult Culex annulirostris had not changed significantly from stage 1 levels. The trend for this species and for Anopheles annulipes was upward, and one can only speculate on population levels when the marginal vegetation has fully established. Due to the extensive loss of marginal vegetation and the creation of expanses of shallow muddy pools, especially towards Toonpan, Anopheles amictus and Aedes normanensis populations increased by 36-fold and 282-fold, respectively (Figure 9.2). The ramifications of this are interesting as Aedes normanensis is well recognized as a vector of Ross River virus and Murray Valley encephalitis, especially inland where Anopheles amictus (probably another species complex) has been the source of Ross River, Barmah Forest and Edge Hill viruses. Control of mosquitoes is usually directed at removal of breeding habitat (source reduction) or aimed at larvae which often aggregate in large numbers in discrete sites. Aedes normanensis is ephemeral and its desiccation-resistant eggs characteristically hatch in response to wet season rainfall filling up temporary pools. Plague numbers appear one month and may be gone the next. More accurate definition of these breeding sites, particularly at Toonpan, Antill Creek and Ross River, is required before control options can be considered. As already mentioned, the clearing process created vast expanses of bare muddy pools, particularly at the north-eastern end (e.g. Toonpan). As the lake gradually receded during the dry season, ideal breeding sites were created and populations increased through spring (from September) and also in the late wet season (March to April) when dry sites were refilled by rainfall. Thus, although the land clearing had benefits in eliminating tropical itch mites and some minor mosquito species, it probably paved the way for population growth of Aedes normanensis and Anopheles amictus. This could possibly be considered a dubious swap, although time will tell. Little is known of their biology and their flight range, the latter being of obvious importance to recreational activity at the other end of the lake. Fortunately, however, they are mainly active at night.
