Abstract

The invention discloses ent-kaurane diterpenoid compound and a preparation method and application thereof. The ent-kaurane diterpenoid compound is specifically extracted and separated from Pteris henryi Christ of Pteris of Pteridaceae and named as Pteris henryi Christ butyl-phthalide. Researches prove that the Pteris henryi Christ butyl-phthalide has the obvious anti-virus and HIV-inhibiting activities. The Pteris henryi Christ butyl-phthalide is detected through multiple means such as a superconducting nuclear magnetic resonance spectrum, a high-resolution mass spectrum and a Fourier transform infrared spectrum to determine that the molecular formula is C20H34O3, the molecular weight is 345.2405, and the chemical structural formula is seen in the specification.

Description

technical field [0001] The invention relates to an enantio-kaurane type diterpene compound and its preparation method and application, belonging to the technical field of medicinal chemistry. Background technique [0002] Pterishenryi Chirst is a genus of Pterishenryi Chirst. The plant is a perennial herb with a plant height of 25-40cm. The Pteris genus includes more than 300 species, of which more than 66 species are distributed in China. However, there are only few reports on phytochemical studies of this genus. Our current research on Pteris angustifolia shows that Pteris angustifolia is a perennial herb distributed in limestone areas below 2000m above sea level in Yunnan, Sichuan and Guizhou. The whole herb is used as medicine. Bitter, astringent, cool in nature. Return liver, urinary bladder channel. Heat-clearing and toxic substances removing, astringing sores to stop bleeding, promoting dampness. Indications for burns, rabies bites, traumatic bleeding, profuse ...
