Several types of plants such as stems, leaves, and flowers can be used as natural ingredients for repelling Ae. aegypti, Star anise (Illicium verum) has a chemical compound that can be used as a mosquito repellent. The purpose of this study was to know the potential of star anise essential oil as repellents of Ae. aegypti. This study was an experimental study with post test only with control group design. The experiment to test the repellency of star anise essential oil was carried out using concentrations of 10%, 20%, 30%, 40%, and 50% on 3-5 days old female Ae. aegypti. The result of this study showed that repellency index of star anise essential oil at concentration 10%, 20%, 30%, 40% and 50% during 6 hours were 58.1%; 63.51%; 59.95%; 49.45% and 65.32%.

Potensi Minyak Atsiri Daun Ketumbar (Coriandrum sativum L.) sebagai Pendukung Pangan Fungsional: Kajian Literatur

“…Linalool dapat bereaksi dengan asam dan berisomerisasi menjadi geraniol, nerol, dan α-terpineol, sedangkan linalool bersifat lebih stabil terhadap basa atau alkali. Selain itu, linalool dapat mengalami auto-ignition pada suhu 235 o C dan dapat terdekomposisi pada suhu melebihi 200 o C (Marmulla et al, 2016;Lestari et al, 2019). Namun, pada umumnya minyak atsiri dapat menguap pada suhu kamar jika berinteraksi dengan udara dan dapat berpotensi mengalami oksidasi tanpa mengalami dekomposisi (Deta & Fitri, 2019).…”

“…Namun, senyawa bioaktif pada minyak atsiri dapat berpotensi hilang atau berkurang seiring dengan pengolahan pangan maupun teknik ekstraksi yang tidak tepat (Sendra, 2016). Berdasarkan karakteristik senyawa linalool, diketahui linalool dapat terdekomposisi pada suhu melebihi 200 o C dan dapat mendidih pada suhu 198 o C (Api et al, 2015;Marmulla et al, 2016;Lestari et al, 2019).…”
