Karangpring is one tourist destination villages in Jember district which is popular with beautiful large rose field areas. Therefore, this area grows to be a leading producer of rose flowers in Jember district. However, the bulky presence of these flowers made its price becomes lower in regular days. Local community only uses and sells these fresh flowers as the flower for funeral. The rose flower has a great potency to be explored as a source of rose essential oil production. To date, there is no previous research on studying rose flowers from Karangpring village for its potency on the essential oil production. In this research, rose flowers were subjected to be extracted of its essential oil using two extraction methods, distillation, and enfleurage. Hydrodistillation resulted two phases of distillates, above part formed a cloudy white phase as a normal essential oil extracted from plants, and the lower phase was an aqueous phase containing rose hydrosols. Both phases of these condensates were analyzed using GCMS. Data explained that above phase, with a yield oil of 0.07%, only contains long-chain hydrocarbons such as n-nonadecane, n-heptadecane, 9-nonadecene, and eicosane, while the lower phase only contains 2-phenylethyl alcohol. On the other hand, enfleurage of fresh rose flowers resulted in 0.06% oil yield. GCMS analysis of this oil shows that 2-phenylethyl alcohol, eugenol, and phenylacetic acid are three major compounds which take more than 85% of total rose absolute. The results show that enfleurage is a better method for extracting rose oil in better quality than using the distillation method, in term of the variety of volatile components. Meanwhile, hydrodistillation is still benefiting from producing rose water that is qualified as an industrial additive agent for food and cosmetic productions or even a new potent of agromedicine products.

Cinnamomum sintoc Bl. merupakan tanaman yang memiliki kandungan minyak atsiri di kulit batangnya yang digunakan untuk antioksidan, antihiperlipidemia dan lain-lain. Dari penelitian ini, senyawa metabolit sekunder dari daun sintok (kadar air 54,7%±0,69) diekstrak dengan metanol dan dianalisis dengan reagen spesifik. Daun sintok diekstraksi secara maserasi bertingkat dengan meningkatkan kepolaran pelarut, yaitu n-heksana, etil asetat, metanol. Uji antioksidan dan antihiperlipidemia dilakukan pada setiap ekstrak(HS, ES, MS) menggunakan standar asam galat equivalent. Total fenolik dan total flavonoid dihitung menggunakan kurva standar asam galat dan kuersetin, hasil total fenolik dari setiap ekstrak antara lain HS (39,23±2,79 mg AGE/g); ES (110,77±2,37 mg AGE/g); dan MS (283,63±3,96 mg AGE/g). Aktivitas antioksidan pada ekstrak ditentukan dengan kemampuan ekstrak untuk meredam DPPH sedangkan aktivitas antihiperlipidemia ekstrak ditentukan dengan kemampuan ekstrak untuk menghambat kinerja lipase. Potensi ekstrak daun sintok terhadap antioksidan cukup tinggi hanya untuk ekstrak MS, sedangkan potensi terhadap antihiperlipidemia untuk semua jenis ekstrak.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
