Abstract

The invention discloses the application of effective parts of common andrographis herbs in preparing medicaments with a cancer chemoprevention function. Because effective parts of common andrographis herbs can induce expression of quinone reductase so as to achieve a cancer chemoprevention effect, the effective part of common andrographis herbs can be used for preparing medicaments with a cancer chemoprevention function. According to the invention, effective parts of common andrographis herbs are prepared into a tablet form, and pharmacological experiments prove that the prepared tablet has a strong quinone reductase inducing activity, therefore, the tablet can achieve a better cancer chemoprevention effect. The method for preparing effective parts of common andrographis herbs comprises the following steps: carrying out extraction on all herbs or leaves of andrographis paniculata by using an extraction solvent so as to obtain an extracting solution; concentrating the extracting solution, adding water into the concentrated extracting solution to dissolve, carrying out extraction on the dissolved solution by using a extraction solvent, collecting extract liquor, and then concentrating the extract liquor so as to obtain the effective parts of common andrographis herbs with stable properties and a high pharmacological activity; and the method is simple in preparation process, easy to implement, and easy to operate and control, therefore, the method has extremely broad application prospects.

Description

technical field

[0001] The invention relates to the field of application and preparation of effective parts extracted from Andrographis paniculata, in particular to the application of the effective parts of Andrographis paniculata with cancer chemopreventive effect. Background technique

[0002] According to the 2008 global cancer statistics released by the International Agency for Research on Cancer (IRAC), there were about 12.7 million new cancer cases and 7.6 million cancer deaths worldwide in 2008; among them, the new cancer cases and death cases in developing countries were respectively Accounted for 56% and 64%. On February 4, 2011, the American Cancer Society (ACS) published a global cancer statistics report on the statistics. Brawley of ACS pointed out in his comments that 35% of cancer risk factors are actually preventable. If effective measures are taken, 2.6 million cancer deaths in 2008 (about 7300 cases per day on average) could be avoided.
