THE STUDY ON EFFECT OF EXTRACTS FROM SEVERAL KINDS OF CHINESE CHONGCHA MADE FROM SOME INSECT EXCREMENTS ON SOME MICROORGANISMS

It was studied on effect of extracts from three kinds of medical Chinese Chongcha (a drink similar tea made from some excrements of insects in China) and their original plants on some microorganisms. The results showed that: The extract from complicated Chinese Sanye Chongcha could inhibit Staphylococcus aureus and Bacillus subtilis, strongly, and could stimulate Lactobacillus burglaricus . The pure Sanye Chongcha could stimulate Lactobacillus burglaricus , and inhibit Staphylococcus aureus strongly. The extract from Huaxiang Chongcha, green tea and Sanye Haichang (the original plant of Sanye Chongcha , i. e Malus sieboldii )could inhibit Staphylococcus aureus and Bacillus subtilis, but could not stimulate Lactobacillus burglaricus . That from Chansha (Chinese name of excrement of silkworm) could not inhibit the tested microbes, but could a little stimulate Lactobacillus burglaricus . The ability of antibacteria could increase with the concentration increasing.
