노니의 주요 산지인 사모아, 인도네시아, 중국(하이난), 하와이, 태국, 타히티에서 생산된 노니 열매를 착즙하여 산지별 노니열매 착즙액의 이화학적 특성, 기능성 성분 및 항산화 활성을 비교분석하였다. 산지별 노니열매 착즙액의 pH는 3.63-3.83 수준으로 나타났으며, 색도는 태국산이 다른 산지 노니열매 착즙액보다 L, a, b 값 모두 유의적으로 낮은 값으로 나타났다. 고형분 함량은 $5.97-6.97^{\circ}Brix$ 범위로 하와이산이 $6.97^{\circ}Brix$로 가장 높았으며, 반면 인도네시아산이 $5.97^{\circ}Brix$로 가장 낮은 값을 나타내었다. 태국산이 가장 많은 스코폴레틴과 루틴을 함유하고 있었으며, 인도네시아산이 다른 지역에서 생산된 노니열매 착즙액보다 폴리페놀 함량이 유의적으로 가장 높았다. 항산화 활성 중 DPPH 라디칼 소거능은 인도네시아 > 하와이 > 타히티 > 태국 > 사모아 > 중국 순으로 나타났으며, ABTS 라디칼 소거능은 인도네시아 > 하와이 > 타히티 > 사모아 > 중국 > 태국 순으로 나타나 인도네시아산이 가장 높은 항산화능을 보였다. 이상의 결과, 태국산이 스코폴레틴과 루틴의 함량이 가장 높았으며, 반면 인도네시아산이 가장 우수한 항산화 활성을 가지는 것을 확인하였다.

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.

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.

Objectives: Noni fruit juice (NFJ) is liquor extracted from Morinda citrifolia (noni) fruit and has been used as an herbal remedy in many countries. However, the NFJ's anti-adipogenic and anti-inflammatory effects on adipocytes are poorly understood. The purpose of this study was to explore the commercially standardized NFJ effects on lipid accumulation throughout 3T3-L1 preadipocytes differentiation and interleukin-1β (IL-1β)-mediated inducible nitric oxide synthase (iNOS) expression in 3T3-L1 preadipocytes. Methods: Cellular lipid accumulation and triglyceride (TG) content in differentiating 3T3-L1 preadipocytes were assessed subsequently via the Oil Red O staining and AdipoRed assay. MTS assay was used to examine NFJ cytotoxicity in (differentiating) 3T3-L1 preadipocytes. Immunoblotting and reverse transcriptase polymerase chain reaction analysis were used to measure the expression levels of target protein and mRNA in (differentiating) 3T3-L1 preadipocytes, respectively. Results: NFJ treatment at 150 μL/mL led to a substantial reduction of fat accumulation and TG content during 3T3-L1 adipogenesis with no discernable impact on the cell viability. Of note, while NFJ treatment (150 μL/mL) largely inhibited the CCAAT/enhancer-binding protein-α (C/EBP-α) and peroxisome proliferator-activated receptor-β (PPAR-β) protein expressions, it did not influence PPAR-γ in differentiating 3T3-L1 preadipocytes. Of interest, treatment with IL-1β at 20 ng/mL for 4 hours elicited in firm induction of iNOS mRNA expression in 3T3-L1 preadipocytes. However, NFJ treatment at 100 or 200 μL/mL greatly attenuated the IL-1β-induced iNOS mRNA expression in 3T3-L1 preadipocytes. Conclusions: NFJ has anti-adipogenic and anti-inflammatory effects on (differentiating) 3T3-L1 preadipocytes which are in part intervened via control of the expression of C/EBP-α, PPAR-β, and iNOS.

Animals generally prefer nutrients and avoid toxic and harmful chemicals. Recent behavioral and physiological studies have identified that sweet-sensing gustatory receptor neurons (GRNs) in Drosophila melanogaster mediate appetitive behaviors toward fatty acids. Sweet-sensing GRN activation requires the function of the ionotropic receptors IR25a, IR56d, and IR76b, as well as the gustatory receptor GR64e. However, we reveal that hexanoic acid (HA) is toxic rather than nutritious to D. melanogaster. HA is one of the major components of the fruit Morinda citrifolia (noni). Thus, we analyzed the gustatory responses to one of major noni fatty acids, HA, via electrophysiology and proboscis extension response (PER) assay. Electrophysiological tests show this is reminiscent of arginine-mediated neuronal responses. Here, we determined that a low concentration of HA induced attraction, which was mediated by sweet-sensing GRNs, and a high concentration of HA induced aversion, which was mediated by bitter-sensing GRNs. We also demonstrated that a low concentration of HA elicits attraction mainly mediated by GR64d and IR56d expressed by sweet-sensing GRNs, but a high concentration of HA activates three gustatory receptors (GR32a, GR33a, and GR66a) expressed by bitter-sensing GRNs. The mechanism of sensing HA is biphasic in a dose dependent manner. Furthermore, HA inhibit sugar-mediated activation like other bitter compounds. Taken together, we discovered a binary HA-sensing mechanism that may be evolutionarily meaningful in the foraging niche of insects.

본 연구는 다양한 생리활성을 지닌 노니의 활용성을 향상시키고 기능성이 증진된 노니주스를 제조하기 위하여 미숙과 및 완숙과에 cellulase와 pecitnase를 처리하여 노니주스를 제조하고, 이들의 기능성 성분의 함량 및 생리활성을 효소 무처리 주스 및 6종의 시판 노니주스외 비교하여 측정하였다. 총 폴리페놀 함량은 효소처리 노니 미숙과 주스가 1.61 mg/mL로 유의적으로 가장 높았으며, 스코폴레틴 함량은 효소처리 노니 완숙과 주스가 123.88 ㎍/mL로 유의적으로 가장 높았다. DPPH 라디칼 및 ABTS 라디칼 소거 활성은 효소처리에 의해 증가되었으며, 시판 노니주스보다 효소처리 노니주스가 높은 소거활성을 보였다. 즉, 효소처리 노니 완숙과 주스가 가장 높은 소거활성을 보였으며, 다음으로 효소처리 노니 미숙과 주스가 높은 활성을 보였다. NO 저해능은 효소처리 노니 완숙과 주스와 NJ5가 높은 저해활성을 보였다. 이상의 결과, 효소를 처리하여 제조된 노니 주스는 높은 폴리페놀과 스코폴레틴을 함유하고 있었으며, 높은 산화방지 활성과 항염증 작용을 보였다. 따라서 주스 제조 시 cellulase 및 pectinase 처리는 주스의 기능성 성분의 함량 및 생리기능성을 향상시킬 수 있으며, 특히 노니 완숙과를 이용하여 제조할 경우 그 생리기능성이 크게 향상되는 것을 확인할 수 있었다. 이상의 결과 노니 완숙과를 이용하여 효소처리된 노니주스는 기능성 주스로써의 활용성이 매우 클 것으로 판단된다.
