  • To investigate biological activity of noni extracts treated with HCl and trypsin, we measured the antioxidant activity through vitro assay and cellular system. Both water and lipid soluble fraction of noni extracts dose-dependently scav­enged DPPH radical. Superoxide scavenging activity of lipid soluble fraction after treating HCl and trypsin was significantly more potent than those of other fractions in NBT/xanthine oxidase assay, which suggests that antioxidant activity of noni extracts was increased by the treatment with HCl and trypsin. In antioxidant assay using RBL 2H3 cells, water soluble frac­tion of noni extracts had little effect on silica-induced reactive oxygen species generation, whereas lipid soluble fraction inhibited in a dose dependent manner. In non-treated noni extracts, effect of water soluble fraction on silica/$CuSO_4$-induced lipid peroxidation was more potent than that of lipid soluble fraction. However, the effects of noni extracts were reversed in noni extracts treated with HCl and trypsin. These data suggest that water soluble substances may be converted into lipid soluble substances by the treatment with HCl and trypsin. From the above results, it is suggested that lipid soluble fraction of noni extracts contain antioxidant used in vitro assay and RBL 2H3 cellular system. Such an effect of noni extracts may be increased by the treatment with HCl and trypsin.

  • The purpose of this paper was to study cookies that could be sweetened by consumers through the addition of Morinda citrifolia powder, and also to examine the quality characteristics of such cookies in order to expand the uses of Morinda citrifolia. The addition of Morinda citrifolia powder did not have an observable affect on cookie density, although it did decrease pH levels. A central finding was the lack of significant differences in moisture content of cookies made with Morinda citrifolia powder at the significance level of 5%. Significant differences were found in the diameter, which represents spreadability, in the group of cookies made with Morinda citrifolia powder. The L value decreased considerably with the addition of Morinda citrifolia powder. The control also recorded the highest hardness points and had significant differences from the groups added with 3% and 6% Morinda citrifolia powder. The sensory evaluation results showed no significant differences in the taste, flavor, texture, and overall preference between the group of 6% Morinda citrifolia powder and the control except for color, which suggests that cookies made with 6% Morinda citrifolia powder seem to be ideal.

  • In this study, we investigated maximum yield of radical scavenging activity (RSA) using each of various extraction solvents and procedure from noni friut (Morinda citrifolia). Noni fruits were either sun-dried (FS) or hot-air dried (FO) at $60^{\circ}C$ after steam blanching. For optimum aqueous extraction, noni fruits should be sun dried and autoclave extraction time should not be over 30 min to produce extraction with high RSA with low cost. In case of 50% ethanol extraction, reflux extracts of FS and FO resulted in $IC_{50}$ of 1.92 mg/mL and 3.06 mg/mL at 8 hr. When $IC_{50}$ values were lower than 5 mg/mL, coefficient of correlation was 0.71 indicating that 71% of the phenolic antioxidants in noni fruits were accounted for the activity by scavenging free DPPH. However, coefficient of correlation significantly decreased to 0.63 over $IC_{50}$ values of 5 mg/mL. Autoclave extraction contained chlorogenic acid of $14.69 \;{\mu}g/mL$ and scopoletin of $3.86 \;{\mu}g/mL$. Reflux extraction showed all three compounds, chlorogenic acid ($26.19 \;{\mu}g/mL$), quercetin ($19.59 \;{\mu}g/mL$), and scopoletin ($17.4 \;{\mu}g/mL$). Therefore, the result of this study indicated that the potential antioxidant activities and functional values were obtained significantly with reflux extraction from noni fruit.

  • Wrinkle formation is mainly attributed to the environmental factors such as UV rays, air pollution, smoking and stress etc. Especially, UV rays induce premature skin aging which is characterized by deep wrinkle, leathery dryness etc. Recently, researches on the wrinkle formation and its prevention have been the main theme in cosmetics fields. We have studied the various plant extracts having anti-wrinkle effects and finally showed that Noni (Morinda citrifolia) extracts have the efficacy of promoting the type I collagen synthesis in normal human fibroblast, using PICP assay. We purified one active compound from Noni extracts and identified its structure. It was identified as 6,7-Dimethoxy-2H-1-Benzopyran-2-one; scopoletin by $^1H-NMR,\;^{13}C-NMR,$ IR, Mass analysis. Scopoletin increased collagen synthesis in a dose dependent manner (89.5% at $0.2{\mu}g/mL$). In order to verify the anti-aging effectiveness of the cream containing 3% noni extracsts, we performed the in vivo test with some female volunteers for 12 weeks. It reduced the signs of aging, especially face wrinkles. From these results, we conclude that the noni extracts could be used as an useful anti-wrinkle agent.

  • Rubiadin, a major compound of noni ($Morinda$ $citrifolia$) adventitious root, is highly valued in pharmaceutical industry due to hepatoprotective activity. To dissect rubiadin's effective extraction condition, extraction process of noni adventitious roots was performed with different solvent types, ratio of water to methanol (water, 20, 40, 60, 80, and 100% of methanol), extraction time, and extraction method. In contrast, we also developed a reverse- phase HPLC assay method to determine rubiadin from noni adventitious roots. The HPLC assay of rubiadin was performed by C-18 column using a gradient solvent system of methanol and water with UV detector at 280 nm. The extraction efficiency of different types of solvents were increased in order of methanol (0.08%) > ethanol (0.05%) > acetonitrile (0.03%) > acetone (0.02%) and methylene chloride (0.02%). The results of rubiadin extraction using different solvents showed that 1 hour of ultrasonic extraction was effective in order of 60% methanol (0.21%) > 80% methanol (0.13%) > 100% methanol (0.07%), 40% methanol (0.07%) and 2 hours of reflux extraction was effective in order of 60% methanol (0.21%) > 40% methanol (0.17%) > 80% methanol (0.14%). To compare the extraction efficiency of rubiadin according to the extraction methods and time for high rubiadin content, the extracts of rubiadin in noni adventitious roots were isolated with the methods of ultrasonic extraction, shaking extraction and reflux extraction. Rubiadin extracted from the methods of ultrasonic waves and shaking displayed the highest contents at 8 and 24 hours, respectively.

  • This study analyzes the economic feasibility on the transition of production structure to increase income for a local forest village in Laos PDR. The study area was the Nongboua village in Sangthong district where the primary product is rice from rice paddy. Possible strategies were considered to increase the villagers' revenue, and Noni (Morinda citrifolia) was production in the short-term. We assumed that the project period was for 20 years for the analysis, and a total of 1,100 Noni tree was planted in 1 ha by $3m{\times}3m$ spacing. This study classified basic scenario one, scenario two, scenario three by the survival rate and purchase pirce of Noni. Generally Noni grows well. However, the seedlings' average survival rate (= production volume) was set up conservatively in this study to consider potential risks such as no production experience of Noni and tree disease. The scenario one assumed that the survival rate of Noni seedlings was 50% for 0-1 years, 60% for 0-2 years, and 70% for 3-20 years; the scenario two, 10% less, i.e., 40%, 50%, and 60%; and the scenario three, 10% less, i.e., 40%, 50%, 60% and purchase price 10% less, i.e., $0.29 to $0.26, respectively. Our analysis showed that all 3 scenarios resulted in economically-feasible IRR (internal rate of return) of 24.81%, 19.02%, and 16.30% of with a discounting rate of 10%. The B/C (benefit/cost) ratio for a unit area (1ha) was also analyzed for the three scenarios with a discounting rate of 10%, resutling in the B/C ratio of 1.71, 1.47, and 1.31. The study results showed that the Nongboua village would have a good opportunity to improve its low-income structure through planting and managing alternative crops such as Noni. Also the results can be used as useful decision-making information at a preliminary analysis level for planning other government and public investment projects for the Nonboua village.

  • The objectives of this study were to compare the physicochemical properties, functional components and antioxidant activities of noni fruit juices from six different regions of cultivation: Samoa, Indonesia, China (Hainan), Hawaii, Thailand and Tahiti. The pH values of noni fruit juices ranged from 3.63 to 3.83, and the soluble contents were $5.97-6.97^{\circ}Brix$. In regard to color, the L, a and b values of noni juices were in the ranges of 33.41-46.51, 3.44-7.98, and 2.42-22.20, respectively. The polyphenol content of noni fruit juice from Indonesia was significantly higher than other samples. The Thailand noni fruit juice contained the highest amounts of scopoletin (8.62 mg/100 mL) and rutin (2.03 mg/100 mL). The noni fruit juice from Indonesia showed the higher antioxidant activities (DPPH and ABTS radical scavenging activity) than others. In conclusion, These results suggest that noni fruit juice may be a good source of functional food with antioxidant activity and can serve as the basis data for the use of noni fruit in the food industry.
