Jeruk limau merupakan bahan alam dengan beragam manfaat, namun penelitian mengenai pemanfaatannya masih terbatas. Penelitian ini bertujuan untuk menguji potensi minyak atsiri kulit jeruk limau dalam aktivitas antitirosinase, antielastase, dan antibakteri penyebab jerawat. Metode ekstraksi minyak atsiri menggunakan metode Microwave-Assisted Hydro-Distillation (MAHD), sedangkan analisis senyawa kimia dilakukan dengan GC-MS. Pada uji antitirosinase, asam kojat memiliki IC50 sebesar 4,96 µg/mL, sedangkan minyak atsiri kulit jeruk limau memiliki IC50 sebesar 251,36 µg/mL. Pada uji antielastase, kuersetin sebagai pembanding memiliki nilai IC50 24,1 µg/mL, sementara minyak atsiri kulit jeruk limau memiliki IC50 sebesar 46,56 µg/mL. Uji aktivitas antibakteri terhadap bakteri P. acnes menunjukkan zona hambat sebesar 13,04-16,05 mm, sedangkan pada S. aureus menunjukkan zona hambat 15,06-22,16 mm yang berpotensi kuat dalam menghambat bakteri penyebab jerawat. Hasil analisis GC-MS menunjukkan keberadaan senyawa aktif seperti sitronelol, d-limonena, sitronelal, β-pinena, dan α-terpeniol dalam minyak atsiri. Senyawa-senyawa tersebut memiliki potensi aktivitas biologis terkait penghambatan tirosinase, elastase, dan bakteri penyebab jerawat. Penemuan ini dapat memberikan kontribusi pada pengembangan produk perawatan kulit yang berbasis bahan alam. ......Lime is a natural ingredient with various benefits, but research on its utilization is still limited. This study aims to examine the potential of lime peel essential oil in anti-tyrosinase, anti-elastase, and antibacterial activities against acne-causing agents. The essential oil extraction method used Microwave-Assisted Hydro-Distillation (MAHD), and the chemical compound analysis was conducted using GC-MS. In the anti-tyrosinase test, kojic acid had an IC50 of 4.96 µg/mL, while lime peel essential oil demonstrated an IC50 of 251.36 µg/mL. In the anti-elastase test, quercetin as a comparator had an IC50 value of 24.1 µg/mL, where as lime peel essential oil showed an IC50 of 46.56 µg/mL. Antibacterial activity against P. acnes showed inhibition zones ranging from 13.04-16.05 mm, indicating strong potential, while S. aureus exhibited inhibition zones of 15.06-22.16 mm, suggesting strong potential in inhibiting acne-causing bacteria. GC-MS analysis indicated the presence of active compounds such as citronellol, d-limonene, citronellal, β-pinene, and α-terpineol in the essential oil. These compounds demonstrated potential biological activities related to the inhibition of tyrosinase, elastase, and acne-causing bacteria. These findings could contribute to the development of natural-based skincare products.

Jeruk limau adalah salah satu sumber minyak atsiri yang dapat dijumpai secara mudah di Indonesia, tetapi belum banyak penelitian yang menguji manfaatnya. Penelitian ini bertujuan untuk menguji potensi minyak atsiri kulit jeruk limau dalam menghambat aktivitas enzim tirosinase dan elastase, serta melakukan karakterisasi menggunakan pengukuran massa jenis, indeks refraksi, putaran optik, dan analisis GC-MS. Metode ekstraksi minyak atsiri dilakukan menggunakan distilasi air, kemudian pengujian antitirosinase dan antielastase dilakukan dengan mengukur absorbansi minyak atsiri dalam menghambat enzim menggunakan microplate reader. Asam kojat sebagai pembanding uji antitirosinase memiliki IC50 sebesar 4,26 μg/mL, sedangkan minyak atsiri kulit jeruk limau memiliki IC50 sebesar 235,89 μg/mL. Pada pengujian antielastase, pembanding kuersetin menunjukkan IC50 6,12 µg/mL terhadap enzim elastase, sedangkan minyak atsiri kulit jeruk limau memiliki IC50 sebesar 40,66 μg/mL. Nilai massa jenis minyak atsiri kulit jeruk limau sebesar 0,8317 g/mL, indeks refraksi sebesar 1,467, dan perputaran optik sebesar [α] 25 = +35,10 (c=1, neat, λ=589 nm) yang memberikan informasi awal mengenai kebenaran minyak atsiri yang diteliti. Hasil analisis GC-MS menunjukkan adanya senyawa aktif dalam minyak atsiri, yaitu β-pinena, d-limonena, sitronelal, sitronelol, dan α-pinena. Oleh karena itu, penelitian ini menunjukkan kebenaran minyak atisiri kulit jeruk limau dan potensinya sebagai ihibitor tirosinase dan elastase. ......One such source of essential oil is Citrus amblycarpa, commonly known as kaffir lime, which is readily available in Indonesia, but there have been limited studies exploring its potential applications. This research aims to investigate the inhibitory potential of kaffir lime peel essential oil against tyrosinase and elastase enzymes, while also characterizing its physical and chemical properties through density, refractive index, optical rotation, and GC-MS analysis. The essential oil was extracted using water distillation, and its anti- tyrosinase and anti-elastase activities were evaluated by measuring its absorbance using a microplate reader. The positive control, kojic acid, exhibited an IC50 value of 4.26 μg/mL in the anti-tyrosinase assay, while the kaffir lime peel essential oil sample showed an IC50 value of 235.89 μg/mL. In the anti-elastase assay, the positive control, quercetin, displayed an IC50 value of 6.12 µg/mL, while the kaffir lime peel essential oil sample demonstrated an IC50 value of 40.66 μg/mL. The measured density of kaffir lime peel essential oil was 0.8317 g/mL, with a refractive index of 1.467 and an optical rotation of [α]D25 = +35.10 (c = 1, neat, λ = 589 nm). GC-MS analysis identified several active compounds in the essential oil, including β-pinene, d-limonene, citronellal, citronellol, and α-pinene.
