Ekstrak etanol daun sirsak (Annona muricata L.) dilaporkan memiliki aktivitas antioksidan dengan nilai konsentrasi hambat 50 (IC50) sebesar 14,48 µg/mL. Penelitian ini bertujuan untuk mengetahui sifat fisik dan aktivitas antioksidan dari lulur krim ekstrak etanol daun sirsak. Serbuk kering daun sirsak diekstraksi dengan etanol 70% kemudian dibuat formula lulur krim dengan konsentrasi 1,4%, 2,8%, dan 4,2% lalu dilakukan uji sifat fisiknya. Aktivitas antioksidan ditentukan dengan metode DPPH (1,1-difenil-2-pikrilhidrazil). Hasil penelitian menunjukkan bahwa lulur krim ekstrak daun sirsak pada semua konsentrasi memenuhi semua persyaratan uji sifat fisik sediaan topikal yang baik. Hal ini meliputi organoleptis, homogenitas, viskositas, pH, daya sebar dan daya lekat. Nilai IC50 lulur krim ekstrak etanol daun sirsak dengan konsentrasi 1,4%; 2,8%; dan 4,2% adalah 30,72; 26,82; dan 24,03 µg/mL. Hal ini menunjukkan bahwa sediaan lulur krim ekstrak daun sirsak memiliki aktivitas antioksidan atau penangkapan radikal bebas dengan kategori sangat aktif.
