According to historical records, clove is a plant that attracted Europeans to occupy several regions in Indonesia. As a country with a perfect climate to plant clove, Indonesia has been a major supplier of cloves since the 17th century. Cloves are one of the many spices sought after by Europeans. This plant is the native to Maluku Province – it is not surprising that the Europeans tried to conquer the region to dominate the clove trade. Since then, we have realized that cloves have an important role in changing the taste of food. In addition, cloves are also used as one of the main ingredients of cigarettes thanks to their distinctive and addictive aroma.
During its development, cloves have their own place for Europeans. They then developed clove so that their use was not limited to food and beverages flavoring or clove cigarettes. The cloves are then processed by an extraction process so that we can get oil. From this stage, cloves have taken a big leap because we can use clove extract as fragrances. The extraction process has exposed the fact that cloves have properties that make it one of the spices with a classic taste and aroma. Until now, research on cloves has continued because the demand is always increasing.
Cloves are unique plants because we can use the stalks, leaves, and its buds. The extraction process in each part of the clove will produce essential oil reaching 21.3% with Eugenol content of 78% - 94%. Eugenol is a substance that is useful in making vanillin. The extraction process uses a solvent called N-Hexane and Benzene. The research was conducted to determine the yield with this solvent. The extraction stage is started by drying the clove flowers in the sun for about a week. Then the dried clove flowers were crushed where it would turn into powder. Then the extraction was carried out using Soxhlet extractor with 100 ml of solvent at boiling temperature for -/+ 80 minutes. The results showed that the extraction process with N-hexane solvent had a higher level of Eugenol yield than benzene solvent.
