In this method the plant is permeated with steam.

The first step of creating jasmine absolute is to produce what is called a ‘concrete’ by extracting the oil from the flower petals using a solvent such as hexane or similar purified chemical solvents. Different solvents can produce drastically different oil yields due to their polarities, as one study found that 95% ethanol produced higher yields than diethyl ether, which in turn produced higher yields than hexane. … Avoid flowers that are in full bloom, as their scent has begun to fade. Step 2 Remove the petals from the flower and place in a zippered food storage bag. This is an approximation, so don't worry about getting it perfect. As a result the essential oils and water vapor are released, collected and cooled. Seal the bag, then tap it lightly with a wooden mallet to bruise the petals and release the fragrance oils. The different oils will add different undertones to your … Consequently, this will cause the plant tissues to break down. Step 2 Cover the flowers with alcohol or oil …

Most oils are extracted using steam distillation method. Remove all the extraneous material from the flowers and place the petals in a non-reactive (glass or plastic) container.
