In addition to protein, there are also amino acids, such as γ-methylene glutamic acid, γ-amino-α-methylene-butyric acid, lecithin, purine and alkaloids: peanut alkali, betaine, choline, which is actually impure.
The seeds also contain triterpenoid saponins. The unsaponifiable parts of cotyledons and hypocotyls of seeds are mainly sterols, and stigmasterol, campesterol, cholesterol and 24- methylene cholesterol have been confirmed. The seed coat contains lipids, including hydrocarbon 17. 1%, sterol ester 12.4%, triglyceride 8.4%, diglyceride 9.9%, monoglyceride 25.2% and free fatty acid 3.9%.
It also contains a considerable amount of sterols, 7% of pyrocatechol-type tannins, a small amount of ochrocephalin and anthocyanidin, such as colorless cyanidin and colorless delphinidin, and also contains peanut glycosides that cause goiter. The shell contains glycosides with cardiovascular effects (a substitute of 1, 3, diphenyl propylene glycol-1, 2- ketone -3).
