Objective : This study was performed to assess the effects of Aloe and Violae herba extracts on skin disease and skin beauty. Methods : Anti-oxidant effects were measured by the scavenging for DPPH radical, xanthine oxidase activity. Anti-inflammatory effects were examined by relations in NO synthesis, IL-$1{\beta}$, IL-6, TNF-$\alpha$, NF-kB, COX-2, MAP kinase. The skin wrinkle formation effects were measured by collagenase and elastase activities. The whitening effects were examined by tyrosinase activities, melanin synthesis in MNT-1 cell. Results : 1. In an anti-oxidant test, Aloe and Violae herba extracts showed high radical scavenging activity. 2. In an anti-inflammatory test, Aloe and Violae herba extracts strongly inhibited the lipopolysaccharide(LPS)-induced nitric oxide(NO) release from the RAW 246.7 macrophage cells. Aloe and Violae herba extracts also inhibited the LPS-induced IL-$1{\beta}$ and COX-2 expressions. The inhibitory effects of Aloe and Violae herba extracts on macrophage activation were via the inhibition of NF-kB, evidenced by transient transfection assay. Furthermore, Aloe and Violae herba extracts weakly inhibited the activation of Jun-N-terminal kinase(JNK) but they did not have any effects on p38 MAP kinase in RAW 264.7 cells. 3. In the skin wrinkle formation assay, Aloe extract strongly inhibited collagenase and elastase, whose activity are tightly related with the wrinkle formation. 4. In the skin whitening assay, Aloe and Viloae herba extracts weakly inhibited tyrosinase activity, however, it was not statistically significant. Besides they did not have any effects on melanin synthesis, indicating that they could not be applicable for skin whitening. Conclusion : This study show that Aloe and Violae herba extracts may play a significant role in skin disease and skin beauty.

Experimental studies were done to investigate analgesic and antiphlogistic actions of Violae Herba. Its water extract showed a significant dose dependent analgesic effect against writhing syndrome induced by acetic acid as well as in hot plate test in mice. The extract also showed a significant inhibitory effect against paw-edema induced by egg-white in rats.

본 연구는 지질다당류에 의해 유도된 대식세포주인 RAW 264.7 세포에서 자화지정 추출물이 염증 매개체 생성에 미치는 영향을 조사하고자 하였다. 자화지정 추출물이 대식세포주인 RAW 264.7 세포의 세포 생존 능력에 미치는 영향을 조사 하기 위하여 MTT assay를 실시하였다. 또한, Bio-Plex 사이토카인 분석(cytokine assay)을 통하여 NO, 인터루킨 $(IL)-1{\beta}$, 종양 괴사 인자($TNF-{\alpha}$) 및 IL-6와 같은 다양한 사이토카인(cytokine)의 농도에 의한 자화지정 추출물의 항염증 효과를 조사 하였다. 자화지정 추출물은 LPS로 유도 된 대식세포에서 NO, $IL-1{\beta}$, $TNF-{\alpha}$ 및 IL-6의 농도를 $25{\mu}g/mL$ 이상으로 유의하게 저해하였으며 세포 생존율에는 변화가 없었다. 이러한 결과는 자화지정 추출물이 LPS로 유도된 대식세포에서 $IL-1{\beta}$, $TNF-{\alpha}$ 및 IL-6와 같은 염증성 사이토카인(cytokine)의 억제와 관련된 항염증 효과를 갖는다는 것을 시사한다. 앞으로 자화지정을 이용한 염증질환에 관련된 치료제개발에 새로운 연구가 더 필요한 바이다.

Objectives: The anti-inflammatory and anti-oxidative activities of LCVC (Lonicerae Flos, Citri Pericarpium and Violae Herba Complex) have not been fully elucidated. The purpose of this study was to investigate the mechanisms underlying these effects in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. Methods: The evaluation of the anti-oxidative activity of LCVC was completed via DPPH and ABTS radical scavenging capacity, FRAP assay, measurement of polyphenol and flavonoid, assessment of ROS and NO levels in LPS-induced RAW 264.7 cells. The anti-inflammatory activity was defined by measuring the production of biomarkers (PGE2, IL-1B, IL-6 and TNF-𝛼), proteins (ERK, JNK, P38, Nrf2, Keap1, HO-1 and NQO1) and expressions of genes (iNOS, COX-2, IL-1𝛽, IL-6, TNF-𝛼, Nrf2, Keap1, HO-1 and NQO1) in LPS-induced RAW 264.7 cells. Results: LCVC have polyphenol and flavonoid contents. The results of DPPH and ABTS free radical scavenging capacity and FRAP assay showed that the anti-oxidative activity was increased. Production of ROS, NO, IL-6, TNF-𝛼, mRNA expressions of IL-1𝛽, IL-6, TNF-𝛼, Keap1, iNOS and COX-2 were decreased, and NQO1, Nrf2, and HO-1 were increased. In protein expression, JNK and Keap1 were decreased, NQO1, Nrf2 and HO-1 were increased, and no relationships were observed with the ERK and P38 by LCVC. Conclusions: These results suggest that LCVC may offer protective effects against LPS-induced inflammatory and oxidative responses through attenuating Nrf2/HO-1 pathway and MAPKs pathway. Therefore, we propose that LCVC has anti-inflammatory and anti-oxidative activities that have therapeutic potential in the treatment of inflammatory and oxidative disorders caused by the over-activation of macrophages.

Chinese herbs have been used for a long period of time and less side effects than synthesized chemical drugs. Therefore, using Chinese herbs as natural additives in cosmetics becomes popular in recent years. The methanol extracts of Scutellariae Radix, Lithospermi Radix, Lonicerae Flos, Andrographitis. Herba, Angelicae Dahuricae Radix, Ligustici Rhizoma et Radix, Hedyotis Diffusae Herba, Isatidis Folium, Magnoliae Liliflorae Flos, Forsythiae Fructus, Anmarrhenae Rhizoma, Spirodelae Herba, Gardeniae Fructus, Sophorae Flavescentis Radix, Coptidis Rhizoma, Prunellae Spica, Equiseti Hiemalis Herba, Gentianae Radix, Moutan Radicis Cortex, Fraxini Cortex, Lycii Radicis Cortex, Violae Herba, Lophatheri Herba, Matricariae chamomillae Flos, Taraxaci Herba and Scutellariae Barbatae Herba are used to test the efficiency of inhibiting acne pathogens. Twenty-six Chinese herbs are extracted by methanol, and then condensed to dried powder. These extracts are divided into water-soluble part and DMSO soluble part. These two type solutions are tested for the effect on acne pathogens by paper disc diffusion method. The results show that the substances of water soluble part which are Coptidis Rhizoma, Moutan Radicis Cortex, Scutellariae Barbatae Herba have medium to high activity of inhibiting acne pathogents, and the substances of DMSO soluble part which are Coptidis Rhizoma, Ligustici Rhizoma et Radix, Sophorae Flavescentis Radix, Moutan Radicis Cortex, Scutellariae Radix, Scutellariae Barbatae Herba also have medium to high activity of inhibiting acne pathogens. Using Chinese herbs as natural additives in cosmetics is convenience and valuable application in cosmetceutical research and development. Therefore, it is worth that re-investigation and find out the potential of Chinese herbs being use in cosmetics.
