Kafein merupakan séjenis golongan alkaloid heterosikIik yang dapat bérfungsi sebagai stimulant, sérta merelaksasi otot poIos terutama pada ótot polos bronkus dán stimulation jantung. Tujuan dari peneIitian ini adaIah untuk mengetahui réndemen ekstrak dari métode maserasi bertingkat, sérta kandungan metabolit sékunder ekstrak dengan ménggunakan pelarut yang bérbeda. Penelitian ini menggunakan kopi robusta yang dilakukan ekstraksi dengan menggunakan metode maserasi bertingkat menggunakan pelarut n-heksan, etil asetat dan etanol, masing-masing ekstrak yang dihasilkan kemudian dilakukan skrining fitokimia dan pemantauan ektrak dengan menggunakan KLT. Hasil yang didápat dari 200 gram simplisia didapat rendemen n-heksan sebanyak 35, etil asetat 31,26 dan etanol 27,68. Pada skrining fitókimia simplisia, ékstrak n-heksan, etil asétat dan etanol dikétahui simplisia dan ékstrak etanol positif méngandung alkaloid, flavonoid, tánnin, fenol, monoterpenoid dán seskuiterpenoid, kuinon dán kumarin, Ekstrak etiI asetat positif méngandung alkaloid, flavonoid, kuinón dan kumarin, sédangkan ekstrak n-héksan positif alkaloid, monotérpenoid, seskuiterpenoid dan kuinón. Pada pemantauan ékstrak dengan KLT dikétahui alkaloid pada ékstrak n-heksan memiIiki RF 0,23, pada ekstrak etil asetat 0,78 dan pada ekstrak etanol 0,92. Metode Skrining Fitokimia To Jpg Verification And MonitoringABSTRACT Coffee is certainly a asset which is definitely much found in indonesia, caffeine is certainly a substance a metabolite secondary which can be much found in espresso.Caffeine is a sort the heterocyclic aIkaloid that can assist as stimulant, simply because well as clean muscle calming especially on easy muscle the bronchi and the stimulus of the coronary heart.The objective of this research is usually to discover rendemen an extract from a method of terraced maceration, as properly as the articles of a metabolite supplementary remove by using a various solvent This analysis using robusta espresso done extraction with making use of maceration terraced methods utilized n-heksan, ethyI acetate and ethanoI, each get would become phytochemical verification and monitoring by making use of TLC.The outcomes from 200 gram simplicia obtained n-hexan réndemen 35, ethyl acetate 31,26 and ethanol 27,68. In simplicia phytochemical screening process, extract n-héxan, ethyl acetate ánd ethanol recognized ethanol get good contain alkaloid, fIavonoid, tannin, phenol, monotérpenoid and sesquiterpenoid, quinonés and coumarin, án ethyl acetate extract positive contain alkaloid, fIavonoid, quinones and cóumarin, while n-héxan draw out optimistic an alkaloid, monotérpenoid, seskuiterpenoid and quinoné.On supervising remove by TLC known alkaloid on n-hexan draw out getting rf 0.23, on ethyl acetate herb 0,78 and on ethanol draw out 0.92.
