  • A phenolic glucoside and two steroidal sapogenins were isolated from the aerial part of Solanum Iyratum (Solanaceae). They were identified as 2-hydroxy-3-methoxybenzoic acid glucose ester (1), ${\Delta}^{3,5}$-deoxytigogenin ((25R)-spirosta-3,5-diene) (2), diosgenin (($3{\beta}$, 25R)-spirost-5-en-3-ol) (3), respectively by several spectroscopic methods including IR, MS and NMR. Compound 1 has not been previously isolated from Solanaceae plants. Compounds 2 and 3 are isolated from S. Iyratum for the first time in the present study.

  • Solanum Iyratum Thunb (Solanaceae) has multiple applications in korean traditional medicine because of its cytotoxic, immunological and anti-inflammatory activities. However, no study on the anti-arthritic activity of Solanum Iyratum Thunb has been reported in vivo. Rheumatoid arthritis (RA) is a systemic autoimmune disease with chronic inflammation characterized by hyperplasia of synovial cells in affected joints, which ultimately leads to the destruction of cartilage and bone. Cytokine production were assessed during CIA(collagen-induced arthritis) model mice in lymph node (LN), in knee joint and spleen, using ELISA. DBA/1j mice were immunized with bovine type II collagen. After a second collagen immunization, mice were treated with Solanum Iyratum Thunb (SLT) orally at 400, 200 mg/kg once a day for 4 weeks. The severity of arthritis within the knee joints was evaluated by histological assessment of cartilage destruction and pannus formation. SLT significantly suppressed the progression of CIA and inhibited the production of TNF-alpha and IFN-gamma in serum and spleen cell culture supernatant. The erosion of cartilage was dramatically reduced in mouse knees after treatment with SLT. In conclusion, our results demonstrates that SLT significantly suppressed the progression of CIA. This action was characterized by suppression of arthritis index, cartilage erosion and synovial cell infiltration and the decreased production of $TNF-{\alpha}$, $IFN-{\gamma}$, CD4+, CD19+, CD3+/CD69+ cells (in lymph node), CD11b+/Gr-1 + (in knee joint).

  • Solanum lyratum (Solanaceae) has been used as a traditional analgesic, antipyretic and hepatoprotective agents in Korea. In this study, we investigated the hepatoprotective effect of ethylacetate extract of Solanum lyratum (SL) on the dimethylnitrosamine (DMN)-induced liver damage in rats. Oral administration of SL (150, 300 mg/kg daily for 4 weeks) into the DMN-treated rats remarkably prevented the elevation of serum alanine transaminase, aspartate transaminase and alkaline phosphatase levels.

  • 민간에서 만성간염, 수종, 옹종, 습진, 류마치스성 관절통, 소변분리, 말라리아, 황달을 치료하는데 사용하며, 해열 진통제로 약용하고 있는 배풍등을 metanol (SLM)로 먼저 추출하고 이를 hexane (SLMH), ethylether (SLMEE), ethylacetate(SLMEh), butanol (SLMB) 및 수층 (SLMA) 등 다섯가지의 각 용매별로 분획하여 배풍등의 항균 및 항발암 효과를 연구하였다. 먼저 paper disc method를 이용하여 배풍등의 항균효과를 알아보았다. P. mirabilis, S. aureus, S. marcescens 및 B. substilis의 4가지 사용균주에 배풍등의 각 분획물을 처리한 결과, 모든 균주에서 SLMEA층에서 가장 높은 항균 활성 효과를 나타내었고, 그 다음으로는 SLMEE에서 항균 활성 효과를 나타내었다. 배풍등의 암세포 증식억제 효과(cytotoxicity)를 MTT assay로 실험한 결과, 4종의 암세포주 HeLa, MCF-7, HT-29 및 HepG2 모두 배풍등의 ethylether 분획층인 SLMEE총에서 가장 높은 암세포 증식억제 효과를 보였으며, 암예방 QR유도 활성을 HepG2 세포주를 이용하여 실험한 결과에서도, 다른 분획층에 비해 비극성 용매층인 SLMEE층에서 유의적으로 QR유도 활성을 증가시키는 것으로 나타났다. 이상의 실험 결과를 미루어 볼 때, 극성과 비극성을 둘 다 가지는 SLMEA층에서의 항균활성 물질과 비극성 용매층인 SLMEE 층에서의 암 예방 물질의 단계적인 분리 동정을 통한 생리활성 물질의 개발이 기대되어진다.
