Product Description
Aloe emodin is an anthraquinone compound, appearing as an orange-yellow needle-like crystalline powder. It exists in aloe in its free form or as glycosides in rhubarb, senna leaves, and aloe vera. It crystallizes from toluene or ethanol as orange-yellow needle-like crystals with a melting point of 223–224°C and sublimates in a carbon dioxide stream. It is readily soluble in hot ethanol, ether, and benzene, forming a yellow solution, and also dissolves in ammonia and sulfuric acid solutions, yielding a crimson solution.
The primary sources are the dried roots and rhizomes of Rheum palmatum L., Rheum tanguticum Maxim. ex Balf., or Rheum officinale Baill.

Plant Source—Aloe Vera
Aloe vera (Aloe vera) is a perennial evergreen herb from the Liliaceae family. Also known as Curacao aloe, Chinese aloe, oil onion, American aloe, among other names. The leaves are clustered, large, and thick, arranged in a rosette or at the stem tip, with lanceolate or short, broad leaves edged with sharp teeth. The flower clusters can be umbel, raceme, spike, or panicle, colored red, yellow, or with red spots, with six petals and six stamens. The base of the flower perianth often forms a tubular structure. Aloe vera is one of the few edible species in its genus and is widely used in food, beauty products, health supplements, and medicine. Aloe vera gel is commonly used in beverages, jellies, yogurts, and canned foods. However, aloe also has certain toxic properties, and it is not recommended for pregnant women or young children. Aloe vera contains 75 elements, closely matching those required by human cells, and is known for its significant health benefits, earning it the titles “miracle plant” and “home medicine cabinet.”
