Constituent of Capsicum annuum variety fascuilatum
Capsianosides are acyclic diterpene glycosides, water-soluble constituents present in the fruits of Paprika (Paprika Capsicum annuum L. variety grossum Bailey) and Jalapeno (Jalapeno Capsicum annuum L. variety annuum), that are used as vegetables and spices. Paprika is known for its high vitamin C content and has been isolated from Hungarian paprika in large amounts. Jalapeno is a stimulating spice which contains capsaicin and related compounds in its fruits and veins. (PMID: 17015971); The genus Capsicum (Solanaceae) includes many species widely cultivated in Asia, Africa, and Mediterranean countries. Peppers are native plants of America, and the fruits (pericarps) are consumed as vegetable foods, spices, and external medicines and are also a source of vitamins A, C, and E. Hot chili pepper has been used for centuries as a condiment to aid digestion. Traditionally, medical doctors advise ulcer patients not to consume spicy foods like pungent capsicum products, while naturopaths and herbalists have tended to use hot seasonings to relieve ulcers. Phytochemical investigations have been mainly focused on hot components of pepper species and qualitative and quantitative determinations of phenolic metabolites with antioxidant activities. (PMID: 17002415). Capsianoside I is found in many foods, some of which are italian sweet red pepper, pepper (c. annuum), yellow bell pepper, and herbs and spices.
