ABSTRACT
Soursop leaves (Annona muricata L.) is one of the medicinal plants of Annonaceae family that has great benefits for human life. The purpose of this study is to determine the development of chemical components at several levels of leaf age development by using gas chromatography equipment on young and old soursop leaves. The chemical components of soursop leaves are extracted into methanol and water solvents then derivatized with MTBSTFA prior to injection into gas chromatography. Changes in chemical components of soursop leaves can be seen as peak chemical content in Gas Chromatography. From the analysis there are 13 compounds which is the peak in the sample of young soursop leaves, 11 peaks on the leaves of soursop and the oldest 14 peaks on old soursop leaves. The content of chemical components in soursop leaves varies according to the leaf age progression rate. Some chemical components decrease with the older leaf age, some chemical components increase in the leaves of the old half and decreases in the old leaves. Some chemical components do not change in young and half-old leaves but are reduced to older leaves. The results of this study indicate that gas chromatography method can be used to analyze chemical components in soursop leaf.

ABSTRAK
Daun Sirsak (Annona muricata L.) merupakan salah satu jenis tanaman obat dari familia Annonaceae yang mempunyai manfaat besar bagi kehidupan manusia. Tujuan penelitian ini untuk menentukan perkembangan komponen kimia pada beberapa tingkat perkembangan umur daun dengan mengunakan peralatan Kromatografi Gas pada daun sirsak muda setengah tua dan tua. Komponen kimia pada daun sirsak diekstraksi ke dalam pelarut metanol dan air kemudian diderivatisasi dengan MTBSTFA sebelum injeksi kedalam kromatografi gas. Perubahan komponen kimia pada daun sirsak dapat terlihat puncak kandungan kimia pada Kromatografi Gas. Dari hasil analisis terdapat 13 senyawa yang merupakan puncak pada sampel daun sirsak muda, 11 puncak pada daun sirsak setengah tua dan 14 puncak pada daun sirsak tua. Kandungan komponen kimia dalam daun sirsak berubah-ubah sesuai dengan tingkat perkembangan umur daun. Beberapa komponen kimia berkurang dengan makin tua umur daun, sebagian komponen kimia meningkat pada daun setengah tua dan menurun pada daun tua. Sebagian komponen kimia tidak berubah pada daun muda dan setengah tua tetapi berkurang pada daun tua. Hasil penelitian ini menunjukan bahwa metode kromatografi gas dapat digunakan untuk menganalisa komponen-komponen kimia pada daun sirsak.
