Morinda citrifolia, also known as Great Morinda, Indian Mulberry, or Noni, is a plant belonging to the family Rubiaceae. A number of major chemical compounds have been identified in the leaves, roots, and fruits of the Noni plant. The fruit juice is in high demand in alternative medicine for different kinds for illnesses such as arthritis, diabetes, high blood pressure, muscle ached and pains, menstrual difficulties, headache, heart diseases, AIDS, gastric ulcer, sprains, mental depression, senility, poor digestion, arteriosclerosis, blood vessel problems, and drug addiction. Several studies have also demonstrated anti-inflammatory, antioxidant and apoptosis-inducing effects of Noni in various cancers. Based on a toxicological assessment, Noni juice was considered as safe. Though a large number of in vitro, and, to a certain extent, in vivo studies demonstrated a range of potentially beneficial effects, clinical data are essentially lacking. To what extent the findings from experimental pharmacological studies are of potential clinical relevance is not clear at present and this question needs to be explored in detail before an recommendations can be made.

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.

To investigate anti-inflammatory activity of Noni extracts, we measured the phospholipase $A_2$ activity using both in vitro and in vivo system. Water soluble fraction of Noni extracts did not affect melittin-induced arachidonic acid release, whereas lipid soluble fraction inhibited it in a dose dependent manner in Raw 264.7 cells. The purified phos­pholipase $A_2$ activity was dose-dependently inhibited by lipid soluble fraction of Noni extracts but not by its water soluble fraction. Lipid peroxidation, myeloperoxidase and phospholipase $A_2$ activity in incised skin of mice were significantly increased as compared with those in non-incised skin, and these increase was attenuated by the treatment with Noni pow­der. Our data suggest that Noni extracts has anti-inflammatory activity, and this is, in part, caused by inhibitory activity of phospholipase $A_2$.

본 연구는 노니(Morinda citrifolia)에 함유된 주요 생리활성물질이 RAW 264.7 세포에서 JAK/STAT 신호전달 경로를 통하여 항염증 작용에 관여하는 것을 조사하였다. 건조된 M. citrifolia 열매의 MeOH 추출에 의한 유기용매의 순차 분획에서 얻은 EtOAc 분획물(Mc-EtOAc)에서 가장 높은 항산화 활성을 확인하였고, H₂O₂로 유도된 RAW 264.7 세포의 산화적 스트레스에 대한 세포보호 효과는 처리 농도의존적으로 세포독성을 차단하였다. LPS 처리로 71.6%의 RAW 264.7 세포 생존율에서 240 ㎍/ml의 Mc-EtOAc를 전처리한 군에서 84.5%의 세포 생존율 증가를 보였다. LPS로 유도된 RAW 264.7 세포의 NO 생성 저해활성은 240 ㎍/ml의 Mc-EtOAc에서 양성 대조군의 절반 수준으로 NO의 생성양을 감소시켰다. Mc-EtOAc 처리로 iNOS의 발현량은 농도의존적으로 유의하게 감소하였고, COX-2의 발현은 LPS 유도로 3배 정도로 증가되었으나, 120, 240 ㎍/ml의 Mc-EtOAc를 전처리시 농도의존적으로 유의하게 감소시켰다. 또한 pro-inflammatory cytokine IL-1β와 TNF-α의 mRNA 발현도 억제하였다. 이러한 Mc-EtOAc의 항염증 작용이 상위 신호전달 경로인 JAK/STAT 신호전달 경로 통해 일어나지를 조사한 결과, Mc-EtOAc의 전처리로 LPS로 유도된 RAW 264.7 세포에서 pJAK1과 pSTAT3의 인산화 정도가 유의성 있게 감소하였다. 따라서 RAW 264.7 세포에서 Mc-EtOAc의 항염증 효과는 JAK1/STAT3 신호전달 경로를 통해 염증반응을 억제하는 것으로 사료된다.
