Embodiment 1

[0009] The method for extracting diaryl heptane compound 5-hydroxyl-1-(4-hydroxyphenyl)-7-phenyl-3-heptanone from Galangal, comprises the steps:

[0010] (1) 3.5 kilograms of galangal medicinal materials are pulverized, (galangal was purchased from Tianjin Chinese Herbal Pieces Factory in March, 2004, identified by the Pharmacy Teaching and Research Office of Tianjin Medical University) plus 10 kilograms of ethanol aqueous solution with a concentration of 90% by volume, heated to reflux for 6 After 1 hour, the extract was filtered, extracted 3 times, and the filtrate was concentrated under reduced pressure to 50°C when the relative density was 1.10 extract (300g), added distilled water 4 times the mass of the extract to dissolve, extracted 3 times with chloroform, The extract was concentrated under reduced pressure to obtain 150 g of chloroform extract. The extract was separated by silica gel column chromatography (1.2 kg, 100-200 mesh), and petroleum ether- Gradient elution ...

Embodiment 2

[0015] Antibacterial activity of 5-hydroxy-1-(4-hydroxyphenyl)-7-phenyl-3-heptanone

[0016] 5-Hydroxy-1-(4-hydroxyphenyl)-7-phenyl-3-heptanone has been shown to have anti-Candida albicans (Candida albicans) activity by in vitro disc method antibacterial experiments, and its minimum inhibitory concentration (MIC) as follows:

[0017]

Embodiment 3

[0019] Combining 5-hydroxy-1-(4-hydroxyphenyl)-7-phenyl-3-heptanone with a pharmaceutically acceptable carrier to prepare various dosage forms for treating diseases caused by Candida albicans.

Abstract

The present invention discloses the use of 5-hydroxy -1-(4- hydroxyphenyl)-7- phenl-3- heptanone in preparing medicine for resisting candida albicans. Experiment shows that 5-hydroxy -1-(4- hydroxyphenyl)-7- phenl-3- heptanone extracted from galagal rhizome through a modern separation process has function of resisting candida albicans. The present invention lays foundation for developing new antifungal medicine.

Description

technical field [0001] The invention relates to an application of extracting compounds from traditional Chinese medicines, in particular to an application of extracting diarylheptane compounds from galangal. Background technique [0002] The traditional Chinese medicine galangal is one of the commonly used traditional Chinese medicines. It has the effects of warming the stomach, expelling wind, dispersing cold, promoting qi and relieving pain. It is widely used in seasoning among the people. Clinically, it is often used in the treatment of cold pain in the abdomen, cold stomach and vomiting, indigestion, acid regurgitation and other diseases. Modern chemical and pharmacological studies have shown that galangal has complex chemical components, strong pharmacological activity, and strong anti-ulcer, anti-diarrhea, choleretic, analgesic, anti-inflammatory, anti-hypoxic, anti-coagulant, and anti-thrombotic effects. It has been clinically proven for many years that galangal has...
