Several parts of the Bitter Orange tree can be distilled to produce essential oils, each with a very different biochemical composition: Neroli (orange blossom) comes from the flowers of the plant, bitter orange oil from the peel and petitgrain EO from the leaves. For Citrus aurantium ssp aurantium leaves, the yield is around 0.7%, as 100 kg of distilled leaves yield 700 grams of essential oil.
