Citronella oil is an essential oil obtained from the leaves and stems of different species of Cymbopogon (lemongrass). The oil is used extensively as a source of perfumery chemicals such as citronellal, citronellol, and geraniol. In Indonesia in general, there are 2 types of fragrant lemongrass or citronella lemongrass (Cymbopogon nardus), namely the type of mahapengiri and the type of lenabatu. Mahapengiri can be identified from the shape of the leaves are shorter and wider than the leaves that are lenabatu. With distillation, this type gives higher oil yields than lenabatu, also of better quality, meaning that the content of geraniol and citronellal is higher than lenabatu. We use mahapengiri as the raw material for citronella oil and we always recommend farmers who are our partners to always use mahapengiri as the seeds of the citronella plant that are planted.
