Alpha-Angelica Lactone CAS 591-12-8

Alpha-Angelica Lactone is a light yellow to brown oily liquid with the characteristic medicinal aroma of Angelica sinensis. It is widely used in the field of nutraceuticals as the main active ingredient of Umbelliferae (e.g. Angelica sinensis, Rhizoma Ligustici Chuanxiong), and its volatility and photosensitivity are prominent. It needs to be stored in an inert atmosphere away from light to avoid oxidative degradation.
