Abstract

The invention relates to corydalis and corydalis of isodon macrophylla which are extracted and separated from the isodon macrophylla and have the structural formula of ent-abietane diterpenoids, a preparation method and applications thereof. A plurality of in vitro anti-tumor activity experiments show that the compounds have significant effect of inhibiting the activity of tumor cells and can be applied in the preparation of medicaments for treating cancers and/or tumors. The invention can also provide the lead compounds for developing new medicaments for treating various common multiple cancers, thereby having important significance on developing and utilizing medicinal plant resources of China.

Description

technical field [0001] The present invention relates to the field of medical technology, in particular to enantio-abietane-type diterpene compounds macrophynin E, decane (macrophynin E, F) isolated from Chinese macrophynin and its preparation method and application . The above-mentioned compound has strong inhibitory effect on various tumor cell lines, and can be used as a lead compound for developing new anti-tumor drugs, and can also be used as a drug for treating various common clinical multiple cancers. Background technique [0002] Isodon plants belong to the Lamiaceae (Labiatae=Lamiaceae) Ocimoideae, and are perennial herbs, shrubs, and semi-shrubs with thick, woody rhizomes that are lumpy. There are more than 150 species of plants in this genus, which are produced from southern Africa to tropical Africa (a few species), tropical and subtropical Asia, north to Japan, the Russian Far East, and a few species from Malaysia to Oceania and Pacific Islands. There are 90 sp...
