Extraction of essential oil from kaffir lime (Citrus hystrix) leaves using microwave-assisted extraction / Siti Nurfatihah Azmi, Muhammad Syafiq Hazwan Ruslan

Citrus hystrix DC or normally known as kaffir lime is a citrus species from the Rutaceae family with valuable properties that have attracted the interest of the public. Not only that but the leaves and fruits of the kaffir lime also have a diverse range of essential oils and are therefore used for e...
