Jasmine flowers are picked manually between dawn and 10 a.m., during the hot season in India even between 3 - 8 a.m. Preferably only half-opened and fresh fully opened flowers must be picked, not buds or old (yellowish) flowers, as these will depress the quality of the essential oil. Although rain makes the flowers almost useless, picking flowers in the rain should continue, to promote further flowering[

Jasmine flowers must be quickly processed, since delay substantially reduces essential oil content. Flowers should be kept shaded and cool between picking and processing and the processing facility should be close to the plantation.

Jasmine oil can be obtained from flowers by steam distillation but the yield is very low. Jasmine concrete is obtained from flowers, formerly by enfleurage, currently by solvent extraction. In solvent extraction, flowers are washed up to 3 times with petroleum ether or, preferably, with hydrocarbon-free food-grade hexane; the extract is then distilled to remove the solvent, resulting in the concrete. Concrete is usually produced at the plantation, but absolute is produced where convenient, often in another country[
