Assay-guided fractionation of the ethanol extract of Nymphaea odorata resulted in the identification of two lignans, one new (1) and one known (2), together with six known flavonol glycosides (3-8). The structures of 1-8 were established by spectroscopic analysis as nymphaeoside A (1), icariside E(4) (2), kaempferol 3-O-alpha-l-rhamnopyranoside (afzelin, 3), quercetin 3-O-alpha-l-rhamnopyranoside (4), myricetin 3-O-alpha-l-rhamnopyranoside (myricitrin, 5), quercetin 3-O-(6' '-O-acetyl)-beta-d-galactopyranoside (6), myricetin 3-O-beta-d-galactopyranoside (7), and myricetin 3-O-(6' '-O-acetyl)-beta-d-galactopyranoside (8). Compounds 3, 4, and 7 showed marginal inhibitory effect against fatty acid synthase with IC(50) values of 45, 50, and 25 microg/mL, respectively.

    ABSTRACT: Epidemiological studies have revealed that a diet rich in plant-derived foods has a protective effect on human health. Identifying bioactive dietary constituents is an active area of scientific investigation that may lead to new drug discovery. Kaempferol (3,5,7-trihydroxy-2-(4-hydroxyphenyl)-4H-1-benzopyran-4-one) is a flavonoid found in many edible plants (e.g. tea, broccoli, cabbage, kale, beans, endive, leek, tomato, strawberries and grapes) and in plants or botanical products commonly used in traditional medicine (e.g. Ginkgo biloba, Tilia spp, Equisetum spp, Moringa oleifera, Sophora japonica and propolis). Some epidemiological studies have found a positive association between the consumption of foods containing kaempferol and a reduced risk of developing several disorders such as cancer and cardiovascular diseases. Numerous preclinical studies have shown that kaempferol and some glycosides of kaempferol have a wide range of pharmacological activities, including antioxidant, anti-inflammatory, antimicrobial, anticancer, cardioprotective, neuroprotective, antidiabetic, anti-osteoporotic, estrogenic/antiestrogenic, anxiolytic, analgesic and antiallergic activities. In this article, the distribution of kaempferol in the plant kingdom and its pharmacological properties are reviewed. The pharmacokinetics (e.g. oral bioavailability, metabolism, plasma levels) and safety of kaempferol are also analyzed. This information may help understand the health benefits of kaempferol-containing plants and may contribute to develop this flavonoid as a possible agent for the prevention and treatment of some diseases.

    • "The existence of a 3-hydroxy-propyl group and a glucosyl group were also discerned from the 1 H-1 H COSY spectrum . On the basis of this evidence, as well as by comparison with the literature data (Zhang et al., 2003; Luyengi et al., 1996; Li et al., 1998), 1 was determined to be a neolignan glycoside. Compound 1 was shown to have very similar 1 H and 13 C NMR spectroscopic data to those of 4, 9, 9 0 -trihydroxy-3,3 0 -dimethoxy-8-O-4 0 -neolignan-7-O-b- D-glucopyranoside, a neolignan glycoside, previously reported from Lonicera gracilipes var.

    ABSTRACT: Bioassay-directed fractionation of the antimalarial active CHCl(3) extract of the dried stems of Rourea minor (Gaertn.) Aubl. (Connaraceae) liana led to isolation of two glycosides, rourinoside (1) and rouremin (2), as well as five known compounds, 1-(26-hydroxyhexacosanoyl)-glycerol (3), 1-O-beta-D-glucopyranosyl-(2S,3R,4E-8Z)-2-N-(2'-hydroxypalmitoyl)-octadecasphinga-4,8-dienine, 9S,12S,13S-trihydroxy-10E-octadecenoic acid, dihydrovomifoliol-9-beta-D-glucopyranoside, and beta-sitosterol glucoside. Compounds 1-3 showed weak in vitro activities against Plasmodium falciparum. Their structures and stereochemistry were elucidated by spectroscopic methods and selected enzyme hydrolysis.

    • "During the last few decades, the interest in the study of these plants has increased as they have not been completely studied and their taxonomic relationships are unclear (Les et al., 1999). With regard to chemical constituents, only six species have been previously investigated, and these studies describe the presence of two lignans from N. odorata (Zhang et al., 2003), one hydrolysable tannin from N. tetragona (Kurihara et al., 1993); several glycosyl flavonols from N. x marliacea (Fossen et al., 1998a), N. caerulea (Fossen et al., 1999), N. lotus (Elegami et al., 2003), and N. odorata (Zhang et al., 2003), and various acylated anthocyanins from N. candida (Bendz and Jö nsson, 1971), N. x marliacea (Fossen et al., 1998b; Fossen and Andersen, 1997), and 0031-9422/$ -see front matter Ó 2005 Published by Elsevier Ltd. doi:10.1016/j.phytochem.2005.02.027 N. caerulea (Fossen and Andersen, 1999), as well as two rare macrocyclic flavonoids from N. lotus (Elegami et al., 2003).

    ABSTRACT: Four Mexican Nymphaea species, N. ampla, N. pulchella, N. gracilis and N. elegans belonging to subgenera Brachyceras were analyzed. In this work two 5-glycosyl isoflavones, 7,3',4'-trihydroxy-5-O-beta-D-(2''-acetyl)-xylopyranosylisoflavone (1) and 7,3',4'-trihydroxy-5-O-alpha-L-rhamnopyranosylisoflavone (2), were isolated from N. ampla and N. pulchella, respectively, together with other known 3-glycosyl flavones and triterpene saponins from the same four species. The structures were elucidated by 1D and 2D NMR, FABMS, and other spectroscopic analyses. These results confirmed that the four species were different from each other and established that N. pulchella represents a different taxa than N. ampla. In addition, the 5-glycosyl isoflavones could be considered as a taxonomic character of this group of plants.
