초록

솔장다리(S. collina)는 건조한 대지에 널리 분포되어 있는 한해살이 식물로 한방에서는 고혈압의 치료에 사용되어왔으며 선행연구를 통해 솔장다리가 보유한 항산화 및 항암 활성을 밝힌바 있다. 본 연구에서는 솔장다리 에탄올 추출물(SCEE)의 항비만 활성을 췌장 lipase 효소 활성 억제능과 세포실험계를 이용하여 분석하였다. 그 결과 SCEE는 농도 의존적으로 lipase 효소 활성을 유의적으로 억제시켰으며, 3T3-L1 preadipocyte를 이용하여 지방세포 분화 및 지방생성, 생성된 지방의 분해에 미치는 영향을 분석한 결과 지방세포 분화, 세포 내 지방 축적, TG 함량 등을 독성 없이 농도의존적으로 억제하였고, 지방세포 내 중성지방을 유의적으로 분해시키는 것으로 나타났다. 이러한 솔장다리의 지방세포 분화 억제능은 핵심 작용 인자인 $C/EBP{\alpha}$, $C/EBP{\beta}$, 그리고 $PPAR{\gamma}$의 유전자 및 단백질 발현조절에서 기인함을 확인하였다. 이러한 결과는 솔장다리가 보유한 췌장 lipase 활성 저해능, 지방세포 분화 억제능, 지방세포 내 지방 분해능, 지방분화관련 인자 신호전달기전 조절을 통한 항비만 활성을 처음으로 밝혀낸 것이며 추후 계속적인 연구를 통해 활성 물질의 규명이 필요할 것으로 판단된다.

Salsola collina (S. collina) is an annual plant widely distributed in drought and semi-drought areas, which has been used for a long time as a kind of folk remedy in traditional Chinese medicine for the treatment of hypertension. Previously, the anti-oxidative and anti-cancer activities of S. collina were elucidated in our research group. In this study, the anti-obesity activities of S. collina ethanol extract (SCEE) were evaluated using a pancreatic lipase enzyme inhibition assay and cell culture model. The results showed that SCEE effectively suppressed pancreatic lipase enzyme activity in a dose-dependent manner. Furthermore, SCEE significantly suppressed adipocyte differentiation, lipid accumulation, and triglyceride (TG) content, and triggered lipolysis on insulin, dexamethasone, and 3-isobutyl-l-methylxanthine-treated 3T3-L1 preadipocytes in a dose-dependent manner without cytotoxicity. Its anti-obesity effect was modulated by cytidine-cytidine-adenosine-adenosine-thymidine (CCAAT)/enhancer binding proteins ${\alpha}$ ($C/EBP{\alpha}$), $C/EBP{\beta}$, and the peroxisome proliferator-activated receptor ${\gamma}$ ($PPAR{\gamma}$) gene, as well as protein expressions. Taken together, these results offer the important new insight that S. collina possesses anti-obesity properties, such as pancreatic lipase inhibition and anti-adipogenic and lipolysis effects through the modulation of their upstream signaling pathway. It could become a promising source in the field of nutraceuticals, and the identification of active compounds that confer the biological activities of SCEE may be needed.
