Systemic Lupus Erythematous (SLE) is one of the major autoimmune diseases that can cause severe damage to the tissues and organs in the body and lead to high mortality rates. The clinical manifestations are characterized by the production of autoantibody immunoglobulin G (Ig G) that fights component of the nucleus. The present scientific information issues about peculiar property of Tridax procumbens as immunosuppressant by inhibiting enzyme of cyclooxygenase-2 (COX-2) on surface of B cells. This study approved effect of the extract of Tridax procumbens on human lymphocytes cells line with SLE disease. The aim of this study was to approve effect of extract of Tridax procumbens in suppressing Ig G concentration from patient with stable SLE and patient with active SLE in vitro. This study was an in vitro experimental design on lymphocytes cell line that was isolated from whole blood patient with stable SLE and active SLE. Lymphocyte cells from healthy volunteer were also collected as control. American Rheumatism Association Diagnostic was used for inclusion criteria.Tridax procumbens was extracted with maceration method in solution of ethyl acetate. The extract was divided in several doses as immunosuppressant i.e.1000; 250; 62.5; 31.25; 15.13; and 3.91 Ã‚Âµg/mL. Supernatant of the cultured cells was collected and examined for measuring Ig G concentration as secretion from activated B cells by ELISA. Ethical clearance had been completed before this study started. The extract of Tridax procumbens significantly suppressed Ig G secretion in patient with stable SLE at dose over 62.5 Ã‚Âµg/mL, but Ig G concentration in patient with active SLE was significantly increased when compared with control. Furthermore from the analysis, effect of the Tridax procumbens extract on Ig G concentration followed dose dependent response. In in-vitro study, the extract of Tridax procumbens could significantly suppress Ig G secretion in healthy volunteer and patient with stable SLE. Otherwise, the extract does not suggest for patient with active SLE and it needs caution in use and investigation in-depth. Keywords: SLE, Tridax procumbens, immunoglobulin G ABSTRAK Penyakit Systemic Lupus Erythematous (SLE) merupakan salah satu penyakit autoimun yang sering menyebabkan kerusakan jaringan dan organ sehingga angka kematiannya tinggi. Karakteristik patognomonik penyakit SLE ditandai ada produksi auto antibody immunoglobulin G (Ig G) yang melawan komponen nukleosom tubuh sendiri. Penelitian ilmiah terbaru menunjukkan bahwa ekstrak Tridax procumbens memiliki efek imunosupresan melalui hambatan enzim cyclooxygenase-2 (COX-2) pada permukaan sel B. Pada studi ini menguji efek ekstrak Tridax procumbens pada cells line limfosit dari pasien SLE. Tujuan penelitian ini adalah mengetahui efek ekstrak Tridax procumbens dalam menekan konsentrasi Ig G pasien dengan SLE stabil dan pasien dengan SLE aktif secara in vitro. Penelitian ini merupakan penelitian eksperimen pada cell line limfosit yang diisolasi dari whole blood pasien dengan SLE stabil dan SLE aktif. Kelompok kontrol limfosit diambil dari sukarelawan sehat. Kriteria inklusi pasien yang mengikuti penelitian ini berdasarkan kriteria diagnostik American Rheumatism Association. Tridax procumbens diekstraksi dengan metode maserasi larutan etil asetat. Ekstrak dibagi menjadi beberapa dosis sebagai imunosupresan yaitu 1000; 250; 62,5; 31,25; 15,13; dan 3,91 Ã‚Âµg/mL. Supernatan dari sel kultur dikoleksi dan diukur konsentrasi Ig G yang merupakan sekresi sel B dengan menggunakan metode ELISA. Persetujuan etik dilakukan sebelum penelitian dilakukan. Ekstrak Tridax procumbens menekan sekresi Ig G pasien dengan SLE stabil pada dosis diatas 62,5 Ã‚Âµg/mL, namun konsentrasi Ig G dari pasien dengan SLE aktif meningkat secara signifikan dibandingkan dengan kontrol. Efek ekstrak Tridax procumbens pada konsentrasi Ig G mengikuti dose dependent response. Pada penelitian ini, ekstrak Tridax procumbens dapat menekan sekresi Ig G dari pasien dengan SLE stabil dan sukarelawan sehat. Pemberian ekstrak Tridax procumbens tidak dianjurkan pada pasien dengan SLE aktif, namun hal ini masih membutuhkan penelitian lebih mendalam. Keywords: SLE, Tridax procumbens, imunoglobulin G

Tumbuhan balsem (P. paniculata) merupakan tumbuhan semusim yaitu dari biji lalu tumbuh dan akan mati setelah mencapai dewasa selama 4-5 bulan. Tumbuhan ini berbau balsem sehingga dinamakan tumbuhan balsem oleh masyarakat di Kalimantan Timur. Manfaat tradisional tumbuhan ini tidak banyak dikenal kecuali akarnya dipercaya dapat meningkatkan stamina. Belum banyak hasil penelitian ilmiah tumbuhan ini sehingga diperlukan informasi ilmiah untuk pemanfaatannya. Potensi biologi tumbuhan Balsemadalah mudah tumbuh dengan skilus hidup pendek yaitu 4-5 bulan. Beberapa hasil penelitian terhadap tumbuhan balsem terbukti memiliki potensi dalam bidang kefarmasian seperti sitotoksik atau antikanker, antibakteri, dan antimikotik. Potensi herba balsem juga digambarkan melalui kandungan metabolit sekundernya yaitu mengandung alkaloid, flavanoid, tanin, saponin, dan steroid. Keragaman metabolit sekunder tersebut menggambarkan kemungkinan masih memiliki potensi kefarmasian lainnya. Kata Kunci: Herba Balsem (Polygala paniculata), sumber bahan farmasi potensial. ABSTRACT Plant balm (P. paniculata) is an annual plant that grows from the seed and will die after reaching mature for 4-5 months. This plant is so named smelling balm balm plant communities in East Kalimantan. Traditional benefits of this plant is not widely known but its roots are believed to increase stamina. Not many plants is the result of scientific research that is necessary for the utilization of scientific information. Potential biological plant is easy to grow with skilus Balsemadalah short life is 4-5 months. Several studies have proved the balsam plant potential in the field of pharmacy such as cytotoxic or anticancer, antibacterial, and antimycotic. Potential herbal balm is also illustrated through the content of secondary metabolites that contain alkaloids, flavonoids, tannins, saponins, and steroids. Illustrate the diversity of secondary metabolites may still have potential for other pharmacy.

Dandruff was an anomaly of scalp caused by abnormal growth of Pityrosporum ovale. Ketoconazole and sulfuric compounds known as antifungal, include antifungal against Pityrosporum ovale. One of medicinal plant that has polysulfide compounds was Singawalang (Petiveria alliacea L.). Activity of ethanol extract and fraction of singawalang roots tested using microdilution broth method appropriate to Clinical and Laboratory Standard Institute (CLSI) standard, then growth profiles determined by colony count. Microdilution test results showed that Singawalang roots extract has antifungal activity against Pityrosporum ovale with Minimum Inhibition Concentration (MIC) 16 ÃŽÂ¼g/mL and Minimum Fungicidal Concentration (MFC) 64 ÃŽÂ¼g/mL. Fraction that has highest activity against Pityrosporum ovale was n-hexane fraction of Singawalang roots with MIC 16 Ã‚Âµg/ml dan MFC 128 ÃŽÂ¼g/mL. The higher activity of the extract predicted that there were some polysulfide compounds have synergic activity. Key words : singalawang roots, polysulfide, Pityrosporum ovale ABSTRAK Ketombe adalah suatu keadaan anomali pada kulit kepala disebabkan jamur Pityrosporum ovale dalam jumlah diatas normal. Selama ini antijamur yang digunakan adalah ketokonazol. Selain itu, senyawa sulfur juga diketahui aktif terhadap jamur. Salah satu tanaman yang telah diteliti mengandung senyawa polisulfida adalah tanaman singawalang (Petiveria alliacea L.). Penelitian aktivitasnya terhadap Pityrosporum ovale dilakukan dengan Broth Microdilution sesuai standar Clinical and Laboratory Standard Institute (CLSI). Konsentrasi Hambat Minumum (KHM) terkecil ada pada ekstrak dan fraksi n-heksan, yaitu 16 ÃŽÂ¼g/mL, seperempat dari aktivitas ketokonazol.

The ethanolic extract from the bulb of Eleutherine americana was investigated for acute and subacute toxicity in Balb/C male mice. The parameter used on this research is mortality n hepar histophatological. During acute toxicity study, bulb plant (0.52, 0,26 and 5.2 mg/kg b.wt) p.o. for 72 hour and subacute toxicity study bulb plant (0.52, 0,26 and 5.2 mg/kg b.wt) p.o. once daily for 30 days. The result of the research shows that ethanol extract with 0.52, 0,26 and 5.2 mg/kg b.wt dosage can be said relatively safe because there is no death signal about 50% in 24 hour and the result of subacute toxicity in observation histophatological in hepar shows there is fibrosis n necrosis with 0.52, 2.6 mg/kg b.wt and 5.2 mg/kg b.wt dosage.
