Amomum compactum Soland Ex Maton is one of the Zingiberaceae family plants which is the endemic plants from West Java, Indonesia. This study was aimed to determine the chemical structure of flavonoid compounds from n-hexane extract of A.compactum Sol. Ex Maton roots. Dried powder of the roots was extracted consecutively with n-hexane, ethyl acetate, and methanol solvents. Three flavonoids, 5-hydroxy-3,7,4`-trimethoxy kaempferol (1), 5-hydroxy-3,7,3',4'-tetra methoxy kaempferol (2) and 4'-hydroxy-3,5,7-trimethoxy kaempferol (3), have been isolated from the roots of A. compactum Sol. Ex Maton. The chemical structures of compounds 1-3 were identified by spectroscopy data including infrared 1D-NMR, 2D-NMR and HRTOF-MS as well as by comparison with previously reported spectral data. Compounds 1-3 were isolated from this plant for the first time and showed free radical DPPH scavenging activity.

Dalam penelitian berkelanjutan untuk pencarian senyawa metabolit sekunder baru dari tumbuhan Kalanchoe Indonesia, telah dilakukan kajian fitokimia terhadap Kalanchoe serrata. Daun segar K. serrata sebanyak 14,8 kg diekstraksi dengan metanol pada temperatur kamar. Ekstrak metanol (292 g) dipartisi berturut-turut dengan n-heksana dan metilenklorida. Ekstrak metilenklorida (0,80 g) selanjutnya dipisahkan pada kromatografi cair vakum pada silika gel G60 dengan eluen kloroform-aseton yang meningkat kepolarannya sehingga dihasilkan 10 fraksi yang dikelompokan berdasarkan analisis KLT. Padatan yang diperoleh pada fraksi yang terelusi dengan 20% aseton selanjutnya dipisahkan pada kromatografi kolom pada silika gel (230-400 mesh) dengan eluen kloroform dan dimurnikan lebih lanjut dengan kristalisasi pada aseton sehingga dihasilkan isolat berbentuk kristal jarum tak-berwarna sebanyak 23 mg. Isolat menunjukkan titik leleh 115-118oC dan memberikan warna hijau-kebiruan pada uji Liebermann-Burchard menunjukkan adanya kerangka steroid. Hasil analisis spektroskopi yang meliputi UV, IR, 1D-NMR dan 2D-NMR menunjukan bahwa isolat merupakan turunan sterol dan diidentifikasi sebagai poriferasta-5,22E,25-trien-3β-ol,22-dehidrokolesterol.
