Objectives: To investigate the effect of fermented extract of Artemisiae Iwayomogii Herba, Curcumae Longae, Crataegi Fructus and Salviae Miltiorrhizae Radix (FMH) on anti-inflammation associated with dyslipidemia and anti-oxidation in RAW264.7 and HUVEC cells. Methods: The total polyphenols, total flavonoids, DPPH radical scavenging activity, ABTS radical scavenging activity, and cytotoxicity of FMH were measured. RAW264.7 cells treated with FMH were tested for production of NO, and for cytokine and LTB4 levels and HUVEC cells treated with FMH were examined for production of cDNA of genes related to inflammation. Results: 1. FMH contained polyphenols and flavonoids. The DPPH and ABTS radical scavenging activity of FMH increased in a concentration-dependent manner. 2. FMH treatment inhibited the production of nitric oxide (NO), cytokines, and LTB4 in RAW264.7 cell when compared to the untreated control group. 3. FMH decreased the transcription of pro-inflammatory genes, whereas it increased transcription of anti-inflammatory genes, in HUVEC cells. Conclusion: FMH is effective as an antioxidant and for treatment and prevention of dyslipidemia, atherosclerosis, ischemic heart disease, stroke, and other cardiocerebrovascular diseases.

This study was carried out to obtain the information on the antioxidant activity of Phyllanthus. We compared and analyzed three indigenous collections of Phyllanthus: species from Korea, Brazil and Paraguay. Total phenolic acid contents were $1.93{\pm}0.015$ mg/mL in KCS (Korean Collection Species), $1.65{\pm}0.003$ mg/mL in PCS (Paraguay Collection Species) and $1.49{\pm}0.003$ mg/mL in BCS(Brazil Collection Species). In both DPPH radical scavenging activities and SOD-liked activities, KCS was the highest ($67.25{\pm}0.03%,\;78.38{\pm}1.17%$). KCS were also the highest in hydroxyl radical scavenging activities ($95.80{\pm}0.17%$). It turned out that there was no meaningful difference between BCS ($81.64{\pm}0.23%$) and PCS ($81.54{\pm}0.04%$). As for hydrogen radical scavenging activities, there was no statistically meaningful difference between KCS ($36.44{\pm}0.24%$) and BCS ($36.31{\pm}0.33%$) and it was the lowest in PCS ($33.72{\pm}0.15%$). Our results showed that KCS excelled the others not only in antioxidant activity but also in other beneficial effects. This encouraging results may be potentially useful in developing Phyllanthus urinaria L. variety which contains lots of functional elements such as total phenolic acid.

The ethanol extract of Indigofera cordifolia was studied for in vivo gastroprotective activity, cytotoxic activity against oral tumor and normal cells, multidrug resistance (MDR) reversal activity, anti-human immunodeficiency virus (HIV) activity and radical scavenging activity. The extract of I. cordifolia showed potent gastric mucosal protective activity against stomach injury induced by HCl/EtOH solution. However, the gastroprotective activity could not be related to the radical mechanism, because the extract weakly scavenged both OH radical and $O_2*^-$. The extract also showed promising levels of MDR-reversing activity. This study demonstrates the tumor-specific cytotoxic action of the plant extract. However, the extract had no anti-HIV activity. From above results, the study suggests the medicinal importance of I. cordiforia extract.

6년생 인삼(Panax ginseng C.A. meyer, 연풍)의 뿌리를 주근, 지근, 세근으로 나누고 각각의 중앙부위의 직경에 따라, 직경이 큰 것에서부터 1에서 4까지 등급을 나누었다(MR 1~4, LR 1~4, FR 1~3). 각각의 시료는 동결건조한 뒤 환원당 함량, 페놀함량 및 항산화 효과를 비교하였다. 환원당 함량은 직경에 따른 영향은 없었으나, 주근, 지근, 세근으로 부위가 세분화됨에 따라 환원당 함량이 감소하는 경향을 나타내었다. 총 페놀화합물의 함량은 FR-3이 8.19 mg/g으로 다른 부위보다 2배 정도 높은 페놀함량을 나타내었다. 수소 공여능의 $IC_{50}$값을 비교한 결과 FR-3의 $IC_{50}$ 값이 7.03 mg/mL로 가장 높았고, MR-2에서 37.02 mg/mL로 가장 낮았다. 전체적으로 세근의 수소공여능이 주근과 지근에 비해 높았다. ABTS 라디칼 소거능 역시 FR-3에서 24.87%의 가장 높은 라디칼 소거능을 나타내, 다른 부위보다 세근의 활성이 유의적으로 높음을 알 수 있었다. FRAP value의 측정 결과 역시 FR-3이 $0.23{\mu}M$로 가장 높게 나타났다. 본 연구를 통해 인삼 연풍의 항산화 활성은 주근과 지근보다는 세근에서 유의적으로 높게 나타났으며, 세근 중에서도 직경이 작은 부위에서 높은 페놀함량 및 항산화 활성을 나타내는 것을 알 수 있었다.
