[0002] Rubus hirsutus Thunb. (Rubus hirsutus Thunb.) is a plant of the genus Rubus (Rubus L.) in the Rosaceae (Rosaceae), also known as Yeduli and Sanyuepao. , a large amount of resources; fenugreek is widely used in the folk, and the whole plant can be used as medicine. The fruit part contains chemical components such as phenols, flavonoids and anthocyanins, which have the functions of expelling wind and dampness, clearing heat and stopping bleeding. It is generally used for rheumatic joints Pain, acute jaundice and other diseases; at present, there are relatively few studies on Pompomia at home and abroad, especially the separation and identification of its monomer components and the pharmacological activities of monomer components, and no monomer components have been identified. It is associated with its anti-tumor pharmacological activity, therefore, its usable range as a drug needs to be further expanded

Abstract

The invention discloses a sulfur-containing diene compound and a preparation method and application thereof. The molecular formula of the sulfur-containing diene compound is C17H16O5S; the extraction method of the compound comprises the following steps: leaching rubus hirsutus in an organic solvent to obtain a leaching solution, concentrating the leaching solution, and adding water to prepare a water suspension; extracting the water suspension, and concentrating an extracting solution to obtain an extract; and separating and purifying the extract to obtain the sulfur-containing diene compound. The sulfur-containing diene compound with a novel structure is separated and identified from rubus hirsutus, and the compound has anti-tumor pharmacological activity and can be used for preparing anti-tumor drugs or functional food.
