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.

This study will evaluate the effect of fermented Morinda citrifolia L. extracts and its marker compounds to provide baseline data for utilizing Morinda citrifolia L. as functional health products. Morinda citrifolia L. and six marker compounds were processed on RAW 246.7 macrophage to test for XTT Cytotoxicity, measure Nitric Oxide and Cyokine formation, and analyze the expression of immune marker genes. Furthermore, LPS and fermented red ginseng extract, a common functional ingredient, are used as positive controls. Our results showed that fermented Morinda citrifolia L and six bioactive compounds did not have any cytotoxic effect in all treatment concentrations and groups. Among six bioactive compounds, SCP and ASE confirmed the formation of NO. In addition, the ASE treatment group showed increased formation of IL-6 and IL-1β and the expression of iNOS and TNF-α. Also, fermented Morinda citrifolia L extract activated the macrophage by enhancing the production of nitric oxide (NO), interleukin (IL)-6, and IL-1β, and the expression of COX2 compared to Morinda citrifolia L. extracts. The result of the study showed that Fermented Morinda citrifolia L. (Noni) and marker compound enhance the innate immunity activity and suggested that the bioactive compound could be applied as a marker compound. Thus, Fermented Morinda citrifolia L. (Noni) could be used as functional food material to develop immunity-enhancing products, and highly functional marker compounds can be utilized as the effective components.

This study was carried out to investigate the various roles and effects of Morinda citrifolia L.(noni) on the human body and to utilize the findings obtained for future disease related research on food and nutrition. Morinda citrifolia L. has been used in folk medicine by Polynesians for over 2,000 years and is reported to have a broad range of therapeutic effects. Noni is an alkaloid system such as proxeronine, scopoletin, octanoic acid, terpenoids, alkaloids, anthraquinones, nordamnacanthal, morindone, rubiadin, b-sitosterol, flavone glycosides, linoleic acid, acubin, L-asperuloside, caproic acid, caprylic acid, ursolic acid, rutin. Noni's side effects have been reported to affect anti-inflammatory, analgesics, LDL antioxidant, anti-tumor, antifungal, antibiotic, antiviral, antiparasitic and immunosuppressive effects. In particular, noni's efficacy is considered to be important for the prevention of diseases by inhibiting active oxygen, which is a direct cause of oxidative stress, through various metabolites through 'xeronine system'. Noni's functions and effects that have been examined in this study include anti-inflammation, pain relief, antioxidant, anticancer, hepatocyte protection among others. Therefore, noni's extracts are considered highly useful for diverse scientific and nutritional health functional foods.

Morinda citrifolia adventitious roots were cultured in shake flasks using Murashige and Skoog medium with different types and concentrations of auxin and cytokinin. Root (fresh weight and dry weight) accumulation was enhanced at 5 $mg\;l^{-1}$ indole butyric acid (IBA) and at 7 and 9 $mg\;l^{-1}$ naphthalene acetic acid (NAA). On the other hand, 9 $mg\;l^{-1}$ NAA decreased the anthraquinone, phenolic and flavonoid contents more severely than 9 $mg\;l^{-1}$ IBA. When adventitious roots were treated with kinetin (0.1, 0.3 and 0.5 $mg\;l^{-1}$) and thidiazuron (TDZ; 0.1, 0.3 and 0.5 $mg\;l^{-1}$) in combination with 5 $mg\;l^{-1}$ IBA, fresh weight and dry weight decreased but secondary metabolite content increased. The secondary metabolite content (including 1,1-diphenyl-2-picrylhydrazyl activity) increased more in TDZ-treated than in kinetin-treated roots. Antioxidative enzymes such as catalase (CAT) and guaiacol peroxidase (G-POD), which play important roles in plant defense, also increased. A strong decrease in ascorbate peroxidase activity resulted in a high accumulation of hydrogen peroxide. This indicates that adventitious roots can grow under stress conditions with induced CAT and G-POD activities and higher accumulations of secondary metabolites. These results suggest that 5 $mg\;l^{-1}$ IBA supplementation is useful for growth and secondary metabolite production in adventitious roots of M. citrifolia.

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.

Cervical cancer is the second most common cause of cancer in women and has a high mortality rate. Cisplatin, an antitumor agent, is generally used for its treatment. However, the administration of cisplatin is associated with side effects and intrinsic resistance. Morinda citrifolia (Noni), a natural plant product, has been shown to have anti-cancer properties. In this study, we used Noni, cisplatin, and the two in combination to study their cytotoxic and apoptosis-inducing effects in cervical cancer HeLa and SiHa cell lines. We demonstrate here, that Noni/Cisplatin by themselves and their combination were able to induce apoptosis in both these cell lines. Cisplatin showed slightly higher cell killing as compared to Noni and their combination showed additive effects. The observed apoptosis appeared to be mediated particularly through the up-regulation of p53 and pro-apoptotic Bax proteins, as well as down-regulation of the anti-apoptotic Bcl-2, Bcl-$X_L$ proteins and survivin. Augmentation in the activity of caspase-9 and -3 was also observed, suggesting the involvement of the intrinsic mitochondrial pathway of apoptosis for both Noni and Cisplatin in HeLa and SiHa cell lines.

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.

This study attempted to investigate the possibility of the use of Morinda citrifolia (MC) as a cosmetic ingredient from its physiological activities such as antioxidant activity, cytotoxicity and anti-aging effect. MC is a tropical plant that has been used as traditional polynesian foods and medicines for over two thousand years. It has been reported that this shrub can improve antimicrobial, anti-cancer and anti-inflammatory effects and strengthen an immune system. The in vitro antioxidant activity of MC was performed to see the DPPH scavenging activity by measuring total polyphenol content and total flavonoid content. As a result, a lack of any cytotoxicity was confirmed in human dermal fibroblasts (HDF) cell. When MC extract at a concentration of over $50{\sim}100{\mu}g/mL$ was added, MMP-1 expression considerably diminished. In an in vivo test, in addition, cream containing MC extract was prepared and applied to a total of 22 women in their 30 ~ 50s in ages in the morning and in the evening for four weeks. Changes in keratin, melanin index, pore, skin color and wrinkles under the naked eyes were then comparatively measured. Keratin levels slightly increased in the control group but decreased in the experimental group. In addition, wrinkles diminished in the experimental group. This study found that MC extract controls many MMP-1 related mechanisms with great potential for use as a natural ingredient of anti-aging cosmetics.

Morinda 속 식물은 꼭두서니과(Rubiaceae)에 속하는 다년생 상록관목으로서 전세계 80여종이 분포하고 있다. 그중 노니는 2000년 전부터 동남아시아 지역에서 식품, 향신료, 음료, 자양강장제 등 다양한 분야에 사용되고 있으며 뿌리, 줄기, 잎, 열매의 식물체 전체 부위가 이용되고 있다. 특히 열매는 주스 등 다양한 제품으로 만들어지고 있다. 본 연구는 조직배양된 노니 부정근을 재료로 하여 항알러지의 효능평가를 수행하고 지표물질로 rubiadin을 선정하였으며 이물질에 대한 정제방법 및 구조분석을 통해 정성, 정량적 분석방법을 확립하였다. 항알러지 효능에 대한 측정 결과 노니 부정근 조추출물 $100{\mu}g{\cdot}mL^{-1}$에서 약 85%의 높은 발현 억제 효과를 보였고 이를 분획 추출한 후 분획물별로 histamine 및 $TNF-{\alpha}$ 발현 억제효과를 측정한 결과 헥산 및 메틸렌클로라이드층 분획물에서 효과가 우수하였다. 노니 부정근 조추출물이 함유한 유효성분들 중 항알러지 효과를 나타내는 지표물질을 선정하기 위하여 용매분획을 실시한 후 preparative LC로 분취하여 항알러지 효과가 높은 분획물을 얻었다. HPLC로 분취한 화합물을 GC/MS/MS, LC/MS-IT-TOF, UV/VIS spectrophotometer를 이용하여 최종적으로 rubiadin을 확인하고 이 화합물을 지표물질로 선정하였다. 이러한 결과는 노니 부정근의 고부가가치 기능성 소재로 이용되는데 도움이 될 것으로 기대한다.
