Purification of a n-BuOH-soluble partition of the MeOH extract of Morinda citrifolia (Noni) fruits led to the isolation of two new iridoid glucosides, 6alpha-hydroxyadoxoside (1) and 6beta,7beta-epoxy-8-epi-splendoside (2), as well as 17 known compounds, americanin A (3), narcissoside (4), asperuloside, asperulosidic acid, borreriagenin, citrifolinin B epimer a, citrifolinin B epimer b, cytidine, deacetylasperuloside, dehydromethoxygaertneroside, epi-dihydrocornin, d-glucose, d-mannitol, methyl alpha-d-fructofuranoside, methyl beta-d-fructofuranoside, nicotifloroside, and beta-sitosterol 3-O-beta-d-glucopyranoside. The structures of the new compounds were determined by spectroscopic data interpretation. Compound 4, borreriagenin, cytidine, deacetylasperuloside, dehydromethoxygaertneroside, epi-dihydrocornin, methyl alpha-d-fructofuranoside, and methyl beta-d-fructofuranoside were isolated for the first time from M. citrifolia. The antioxidant activity was evaluated for all isolates in terms of both DPPH and ONOO(-) bioassays. The neolignan, americanin A (3), was found to be a potent antioxidant in these assays.

    ABSTRACT: Specioside (6-O-coumaroylcatalpol) is an iridoid glucoside which possesses multifunctional activities viz. analgesic, antidyspeptic, astringent, liver stimulating and wound healing properties. The present study for the first time delineates stress alleviating and lifespan prolonging action of specioside (SPC), isolated from Stereospermum suaveolens in the free living, multicellular nematode model Caenorhabditis elegans. A strong correlation between lifespan extension and stress modulation in adult worms was established in a dose dependent manner. The dietary intake of this phytomolecule elevated juglone induced oxidative and heat induced thermal stress tolerance in C. elegans. On evaluation, it was found that 25μM dose of SPC significantly extended lifespan by 15.47 % (P≤0.0001) with reduction in stress level. Furthermore, SPC enhanced mean survival in mev-1 mutant suggesting its oxidative stress reducing potential. Furthermore, SPC augmented stress modulatory enzymes superoxide dismutase (SOD) and catalase (CAT) level in C. elegans. Altogether, these findings broadens current perspectives concerning stress alleviating potentials of SPC and have implication in development of therapeutics for curing age related disorders.

    • "Noni is native to Southeast Asia and Australia, and is cultivated in Polynesia, India, the Caribbean, Central and northern South America [2]. Biological compounds such as glycosides, polysaccharides, phenolic compounds, alkaloids, lignans, fatty acid esters, organic acids, vitamins and minerals have been isolated from noni fruits, roots, and leaves [3] [4] [5]. Of the phenolic compounds, the most important reported are anthraquinones: damnacanthal, morindone, morindin, etc, and also aucubin, asperuloside, rutin and scopoletin [5] [6]. "

    ABSTRACT: Morinda citrifolia L. (Noni) fruit harvested in Tepic, Nayarit, Mexico presented alterations in its composition and its properties with the process of senescence during ripening and the seasons of harvest.. Various stages of maturity (stages 1- 4) were examined for their physico-chemical properties (moisture, soluble protein, total carbohydrates, titratable acidity, pH, soluble solids, ash, vitamin C, and phenolic compounds). Generally maturation increased moisture, soluble protein, total carbohydrates, total acidity, vitamin C, and phenolic compounds. During May-June noni fruits (stages 1-4) had the highest levels of soluble protein (8.73-15.63 g/100 g FW), total carbohydrates (6.60-9.60 g/100g FW), ash (0.87- 1.34 g/100 g FW), ascorbic acid (115.85-182.42 mg/100 g FW) and total phenols (3022.8-3647.0 µg/g FW). Middle stage (stage 2) and ripe soft noni fruits (stage 4) had greater total phenolic and rutin (47.18-69.88 µg/g FW-stage 2 and 65.22- 81.34 µg/g FW-stage 4); this profile appears to be independent of season.

    • "A variety of potential health benefits have been reported for noni fruit juice [3]. These include immunomodulation [4] [5] and antioxidant activities in vitro and in vivo [6] [7] [8]. The antioxidant activity of noni juice was found to be associated with increased endurance in athletes [9]. "

    ABSTRACT: Deacetylasperulosidic acid (DAA) is a major phytochemical constituent of Morinda citrifolia (noni) fruit. Noni juice has demonstrated antioxidant activity in vivo and in human trials. To evaluate the role of DAA in this antioxidant activity, Wistar rats were fed 0 (control group), 15, 30, or 60 mg/kg body weight per day for 7 days. Afterwards, serum malondialdehyde concentration and superoxide dismutase and glutathione peroxidase activities were measured and compared among groups. A dose-dependent reduction in malondialdehyde was evident as well as a dose-dependent increase in superoxide dismutase activity. DAA ingestion did not influence serum glutathione peroxidase activity. These results suggest that DAA contributes to the antioxidant activity of noni juice by increasing superoxide dismutase activity. The fact that malondialdehyde concentrations declined with increased DAA dose, despite the lack of glutathione peroxidase-inducing activity, suggests that DAA may also increase catalase activity. It has been previously reported that noni juice increases catalase activity in vivo but additional research is required to confirm the effect of DAA on catalase. Even so, the current findings do explain a possible mechanism of action for the antioxidant properties of noni juice that have been observed in human clinical trials.
