Embodiment example 1

[0045] The preparation of compound described in embodiment case one present invention

[0046] The effective active part A of cat's whiskers is subjected to macroporous resin chromatography, using ethanol-water (0%, 30%, 60% and 95%) as the eluent to obtain 30% macroporous resin elution part A1, 65% human Porous resin elution part A2 and 95% macroporous resin elution part A3. A1 and A3 were systematically separated. A1 was crudely separated by reverse-phase MCI column chromatography, eluted with methanol-water (0:100-100:0) gradient, and 173 fractions were obtained. Fr.34-42 was separated by gel and ODS column chromatography, eluted with methanol-water, traced by thin layer and combined to obtain 12 fractions, which were separated by reversed-phase HPLC preparative chromatography , to obtain compound 1. Fr.63-83 was separated by gel column, eluted with methanol-water system, and the same components were combined by TLC to obtain 13 fractions. The obtained fractions were sep...

Abstract

The invention relates to chemical structures of 11 phenolic acid compounds separated from clinical urinary system resistant active effective parts of Clerodend ranthus spicatus and having novel structures and an application thereof in preparation of medicaments for treating and / or preventing clinical urinary system drug-resistant bacteria. Eight new phenolic acid components are separated from the effective parts by using various separation techniques such as column chromatography. The chemical structures of the separated eight phenolic acid compounds with novel structures are identified by using modern wave spectra techniques (IR, UV, MS, 1D, 2D-NMR), and the compounds are respectively named as Clerodendranoic acid A(1), Clerodendranoic acid B(2), Clerodendranoic acid C(3), Clerodendranoic acid D(4), Clerodendranoic acid E(5), Clerodendranoic acid F(6), Clerodendranoic acid G(7), Clerodendranoic acid H(8), Clerodendranoic acid I(9), Clerodendranoic acid J(10) and Clerodendranoic acid(11). The 11 new compounds have the structural feature of caffeic acid or (and) rosmarinic acid polymers with novel structures.

Description

technical field [0001] The present invention relates to the activity of the whole herb extract from Clerodendranthus spicatus (Thunb) C.Y.Wu (Orthosiphon stamineus Benth.), a medicinal plant of the Lamiaceae Kidney tea genus, by means of phytochemical extraction and separation, against clinical urinary drug-resistant bacteria Eleven new compounds were isolated from the site. The chemical structures of the 11 novel phenolic compounds and their application in the preparation of drugs for the treatment and / or prevention of anti-clinical urinary system drug-resistant bacteria are applied for patent protection. Background technique: [0002] Clerodend ranthus spicatus (Thunb) C.Y. Wu (Orthosiphon stamineus Benth.) is a plant of the genus Kidney tea in the family Lamiaceae. There are only 5 species of this genus in the world, which are produced in Indonesia, Malaysia, Myanmar, the Philippines and other countries in Southeast Asia, and are also distributed in Australia. There is ...
