Senyawa flavonoid yang diperoleh dari bahan alam dapat menurunkan resiko kanker. Tanaman akway (Drimys beccariana, Gibbs) merupakan tanaman endemik di dataran tinggi Papua khususnya di Manokwari. D. beccariana telah banyak digunakan dalam pengobatan tradisional di Papua Barat. Penelitian ini bertujuan untuk mengetahui aktivitas sitotoksik flavonoid dari kulit batang D. beccariana terhadap sel kanker payudara T47D. Senyawa murni hasil isolasi dikarakterisasi dengan menggunakan spektrofotometer UV dan IR, serta diuji aktivitas sitotoksik terhadap sel kanker payudara T47D menggunakan metode Sulforodamin B. Kulit kayu D. beccariana (2,5 kg) diekstraksi dengan pelarut metanol yang selanjutnya dipartisi dengan pelarut n-heksana dan etil asetat. Fraksi etil asetat dipisahkan dan dimurnikan dengan metode kromatografi kolom, diperoleh senyawa murni (7,1 mg). Spektrum UV-Vis senyawa murni menunjukkan dua pita pada ????maks 287 (I) dan 205 nm (II), serta penambahan pereaksi penggeser AlCl3 dengan penambahan panjang gelombang 7 dan 5 nm, spesifik untuk gugus –OH dan C=O pada senyawa flavonoid. Spektrum inframerah senyawa murni (KBr) menunjukkan adanya serapan regang –OH (3422 cm-1), C=O (1659 cm-1), C=C aril (1463 cm-1), dan C-O (1060 cm-1) yang merupakan khas untuk flavonoid. Senyawa murni flavonoid yang diperoleh dari kulit kayu D. beccariana menunjukkan aktivitas sitotoksik terhadap sel kanker payudara T47D dengan nilai IC50 sebesar 3,2 µg/mL. Atas dasar ini, D. beccariana merupakan sumber agen antikanker payudara yang menjanjikan.

Kalanchoe plant, known as “sosor bebek” in Indonesia is a perennial herb and has succulent leaves. The plant is known in folklore and traditional medicine in Indonesia for the treatment of fever, abscesses, bruises, contused wounds, coughs and skin diseases. During the course of our continuing search for novel cytotoxic compounds, the methanolic extract of Kalanchoe tomentosa plants showed cytotoxic activity against P-388 murine leukemia cells. The methanolic extract of the fresh leaves of K. tomentosa was concentrated and extracted successively with n-hexane, ethyl acetate and n-butanol. The ethyl acetate extract exhibited strongest cytotoxic activity againts P-388 murine leukemia cells. By using the cytotoxic activity to follow the separation, the ethyl acetate fraction was separated by combination of column chromatography on silica gel and preparative TLC on silica gel GF254 to afford a kaempferol-3-O-glycosides (1) and kaempferol-3-O-rhamnoside (2). Compound 1 and 2 showed cytotoxic activity against P-388 murine leukemia cells with IC50 > 100μg/mL and IC50 3.32 μg / mL

Penderita diabetes mellitus disebabkan oleh kurangnya sekresi insulin yang diperkirakan mengalami peningkatan dari 8,4 menjadi 21,3 juta jiwa pada 2000 hingga 2030 mendatang. Seiring dengan semakin meningkatnya penderita penyakit diabetes mellitus, maka perlu dilakukan pencarian berbagai alternatif obat herbal dari tumbuhan. Salah satu tumbuhan yang berpotensi sebagai pengobatan diabetes mellitus seperti Sauauria bracteosa yang banyak tumbuh liar di daerah tropis. Tujuan dari penelitian ini menguji aktivitas antidiabetes dari fraksi S. bracteosa diujikan lebih lanjut ke hewan percobaan (tikus). Metode pengujian aktivitas antidiabetes dilakukan dengan metode induksi aloksan terhadap fraksi tumbuhan S. bracteosa dengan dosis 250 mg/kg BB tikus. Induksi aloksan dosis 175 mg/kg BB tikus pada hari ke 0-6. Hasil pengujian aktivitas antidiabetes fraksi n-heksana memiliki aktivitas antidiabetes yang lebih tinggi 43,05% dibandingkan dengan fraksi etil asetat sebesar 33,22% dan fraksi air sebesar 8,88%. Persentase penurunan kadar glukosa kelompok fraksi n-heksana dan fraksi etil asetat pada dosis 100 mg/kgBB menunjukkan penurunan yang lebih tinggi daripada kelompok kontrol positif sebesar 20,93% yang diberikan glibenklamid dosis 0,5 mg/kg BB. Hal ini menunjukkan bahwa tumbuhan S. bracteosa berpotensi kuat sebagai penurun gula darah terutama fraksi n-heksana dan fraksi etil asetat.

Erythrina variegata is a herbal plant commonly used in Indonesia traditional medicine for treatment malaria disease. Acute toxicity test results showed that the methanol extract of E. variegata leaves categorized as practically nontoxic. In this study, we investigated sub chronic toxicity of the extract on male Wistar rats and the procedure based on guidelines of OECD 408 (1998) and EPA OPPTS 870.3100 (1998) for 90 constitutive days. The rats are classified into four dose groups were 0 (control), 250, 500, and 1000 mg/kg body weight with each group consist of five test animals. The results do not show toxic signs either behavior or body weight changed. Hematological analysis and clinical blood chemistry revealed slightly changes but were within the normal limits, except for BUN and SGPT values. Histopathological examination showed an increased damage of liver and kidney cells in form hydropic degeneration, fatty degeneration, as well as necrosis along with increased of extract doses that significantly different with control (p<0.05). However, the damage is reversible and was assumed had not has relations with the treatment. Thus, orally administration of E. variegata extract by dosage 250, 500, and 1000 mg/kg BW did not cause subchronic toxicity on male Wistar rats.

Vernonia amygdalina atau dikenal sebagai daun afrika merupakan salah satu tanaman obat yang berpotensi untuk dikembangkan sebagai nutraceutical, seperti antidiabetes, antimalaria dan antikanker. Penelitian ini bertujuan menentukan aktivitas antioksidan dan aktivitas sitotoksik ekstrak daun V. amygdalina terhadap sel kanker serviks HeLa, serta menentukan kelompok senyawa yang terdapat dalam ekstrak daun V. amygdalina dengan aktivitas sitotoksik dan antioksidan tertinggi melalui penapisan fitokimia. Metode yang digunakan pada penelitian ini adalah ekstraksi dan fraksinasi menggunakan pelarut metanol, etil asetat, dan n-hexana. Semua fraksi diuji aktivitas antioksidannya menggunakan metoda DPPH dan aktivitas sitotoksiknya terhadap sel kanker serviks HeLa menggunakan metode MTS, serta penapisan fitokimia untuk menentukan kelompok senyawa alkaloid, terpenoid, steroid, dan flavonoid. Hasil penelitian menunjukkan bahwa ekstrak etil asetat memiliki aktivitas antioksidan paling tinggi, IC50 ekstrak metanol, etil asetat dan n-heksana berturut-turut adalah: 25,27; 17,89; 213,4 ppm. Hasil uji aktivitas sitotoksik menunjukkan bahwa ekstrak metanol, etil asetat dan n-heksana daun V. amygdalina bersifat kurang aktif terhadap sel kanker serviks HeLa dengan IC50 berturut-turut: 519,42; 249,18 dan 367,24 ppm. Ekstrak etil asetat yang mengandung aktivitas antioksidan tertinggi mengandung kelompok senyawa flavonoid, alkaloid, steroid, dan terpenoid, sehingga berpotensi untuk dimanfaatkan sebagai agen kemopreventif berdasarkan aktivitas antioksidannya.

The ethyl acetate fraction separated from the stembark of Sonneratia caseolaris retrieved three phenolic compounds, including quercetin-3-O-glucoside (1), quercetin (2), and 1-O-(2,4-dihydroxybenzoyl)-β-D-glucopyranose (3). For the first time, compounds 1 and 3 were discovered from Sonneratia genus. Data from various spectroscopic techniques, including mass spectroscopy and one- and two-dimensional NMR, were used to identify their chemical structures. Antibacterial activity has also been assessed for all compounds against Staphylococcus aureus ATCC 25175 and Streptococcus mutans ATCC 6538. Compounds 1–3 displayed varying levels of antibacterial activity against S. aureus and S. mutans. However, all compounds exhibited lower efficacy compared to the control, with their minimum inhibitory concentration (MIC) values ranging from 71.25 to greater than 100 µg/mL. This study provides a foundation for optimizing S. caseolaris phenolic compounds as antibacterial agents and highlights the need for comparative studies within the Sonneratia genus to identify potent bioactive candidates through structural modification or synergistic approaches.
