Abstract

This study was performed to investigate the increasing of immune activities from Centella asiatica L. Urban by several solvent extraction with ultrasonification process. Ethanol extracts at $60^{\circ}C$ and associated with ultrasofication showed more 15% yield than normal $100^{\circ}C$ water extracts. And ethanol extracts showed higher yield than water extraction at each process. It can be concluded that yield due to polarity of compound in C. asiatica from HPLC peak. All of extracts from C. asiatica revealed lower cytotoxicity than 32%. The ethanol extracts with ultrasofication showed higher promotion on human B and T cell growth, about 10% compared to the control. The secretion of IL-6 and TNF-a was also enhanced as $4.86\;{\times}\;10^{-4}\;pg/cell$ and $5.73\;{\times}\;10^{-4}\;pg/cell$ each, by the addition ethanol extracts with ultrasonification to T cell. NK cell activation was improved up to 10% higher than the control, through adding the samples. It can be concluded that the ethanol extracts from C. asiatica has higher immune activities followed by ultrasonification process, possibly, by higher yield than conventional extraction process.

본 연구는 병풀의 초음파 추출 시 용매에 따른 면역활성 증진 효과를 탐색하고자 수행되었다, 각 추출공정의 수율 비교에서 초음파 공정을 병행한 $60^{\circ}C$ 에탄올 추출이 일반 $100^{\circ}C$ 물 추출에 비해 15% 높은 수율을 나타냈으며, 에탄올을 용매로 한 추출이 동일한 조건의 물 추출에 비해 모두 높은 수율을 나타냈다. 이는 용매의 극성과 용출되는 병풀 내 성분의 극성에 기인하는 것으로 사료된다. 인간 정상 섬유아세포인 CCD-986sk를 이용한 세포독성 측정을 통해 모든 병풀 추출물이 32% 이하의 세포독성을 나타냈다. 인간 면역 B, T세포의 생육도 측정에서 초음파를 병행한 $60^{\circ}C$ 에탄올 추출물이 무첨가 대조구에 비해 10%의 증진 효과를 나타내었으며, 면역세포의 cytokine 분비량 측정에서도 IL-6, TNF-$\alpha$의 분비를 각각 $4.86\;{\times}\;10^{-4}\;pg/cell$$5.73\;{\times}\;10^{-4}\;pg/cell$로 나타내 증진 효과를 나타냈다. 또한, 초음파 병행 에탄올 시료를 첨가한 면역 T세포의 분비물에 의한 NK 세포 활성에서도 10%의 생육증진효과를 나타내었다. 이를 통해 병풀의 에탄올 추출물이 면역 활성을 가지고 있으며 초음파 공정을 통해 활성의 증진이 나타날 수 있음을 확인하였다. 이는 에탄올 용매를 통해 병풀 유용성분의 용출이 증진되고, 초음파 공정을 통해 병풀 유용 성분의 수율 향상 및 유용성분의 변화, 신규물질 용출 등이 일어나기 때문인 것으로 사료된다.
