Abstract

The invention discloses a sesquiterpene naphthoquinone compound as well as a preparation method and a medical application thereof, belongs to the field of medicines, and particularly relates to a novel sesquiterpene naphthoquinone compound obtained through separation of dried and mature fruits of cardamom, a preparation method and a medical application. The compound is reported for the first time, can be obtained through extraction, separation and purification of the dried and mature fruits of the cardamom and is high in purity. In-vitro tests prove that the compound can inhibit proliferation of gastric cancer cells, can realize the inhibitory activity separately and can also be combined with other anti-cancer medicines to enhance the inhibitory activity, and a medicine for treating the gastric cancer can be prepared from the compound through development.

Description

technical field [0001] The invention belongs to the field of medicaments, and in particular relates to a sesquiterpene naphthoquinone compound isolated from the dried ripe fruit of cardamom, a preparation method and a medical application thereof. Background technique [0002] Cardamom is a perennial herb. Rhizome stout, brownish red. The leaves are in two rows, the blades are narrow and long-lanceolate, and the leaf sheaths are brownish-yellow pilose. Spikes emerge from the base of the stem. The inflorescence is markedly elongated, the flowers are sparsely arranged, and the corolla is white. The fruit is oblong, with tough skin and not easy to crack. The seed mass is divided into 3 petals, with 5 to 9 seeds in each petal, and the smell of the seeds is fragrant and strong. Mainly produced in Vietnam, Sri Lanka and the Malabar (Malabar) coast of southern India. Harvest when the fruit is ripe, remove the residual fruit stalk, and dry in the sun. Use the dried fruit of ca...
