Sinapic acid is one of the most common hydroxycinnamic acids and is widespread in the plant kingdom. It has been identified in various fruits, vegetables, cereal grains, oilseed crops, some spices, and medicinal plants. Sinapic acid and its derivatives possess antimicrobial, antioxidant, anti-inflammatory, anticancer and anti-anxiety activities.

Aconitic Acid found in leaves and tubers of Aconitum napellus L., Ranunculaceae, in various species of Achillea (Compositae) and Equisetum (Equisetaceae), in beet root, and in sugar cane. It is indicated for the temporary relief of symptoms of chronic illness including fatigue, effects of toxin buildup, slowed metabolism, weakened constitution. The limited data on trans-aconitic acid indicate it to be less toxic than citric acid. Trans-aconitate salts appear to be excreted readily by the kidneys. There is no direct evidence that trans-aconitic acid is utilized as is the cis-aconitic acid isomer in mammalian metabolism although non-specific oxidation probably occurs.
