“…In addition, many phenolic diterpenes such as carnosol, carnosic acid, rosmanol, epirosmanol, isorosmanol, methyl carnosate, and rosmarinic acid might be had added positive effects in sheep diet (Cobellis et al, 2015). Other authors demonstrated that 1,8-cineole (29.52%) and comphor (15.57%) were represent the main compounds in rosemary essential oils (Khayyal et al, 2021). Also, Laurus nobilis L. is known as bay leaf, sweet bay, bay laurel, Roman laurel or daphne, and known AL Ghar in Arabic island of the Lauraceae family and is remain an evergreen Mediterranean shrub whose leaves have traditionally been used in cuisines and folk medicine due to their beneficial health effects, which can nowadays be scientifically explained by various biological activities of the leaf extracts.…”
