Methyl cinnamate

Methyl cinnamate is the methyl ester of cinnamic acid and is a white or transparent solid with a strong, aromatic odor. It is found naturally in a variety of plants, including in fruits, like strawberry, and some culinary spices, such as Sichuan pepper and some varieties of basil.[3] Eucalyptus olida has the highest known concentrations of methyl cinnamate (98%) with a 2–6% fresh weight yield in the leaf and twigs.[4]

Methyl cinnamate is used in the flavor and perfume industries. The flavor is fruity and strawberry-like; and the odor is sweet, balsamic with fruity odor, reminiscent of cinnamon and strawberry.[1]

It is known to attract males of various orchid bees, such as Aglae caerulea.[5]
