Abstract

In the present study, physiological activities of hot water extracts and 70% ethanol extracts of three types of medicinal mushrooms (Hericium erinaceus, Cordyceps militaris, and Ganoderma lingzhi) produced in Korea and China were investigated. Both the hot-water and 70% ethanol extracts of H. erinaceus and C. militaris from Korea displayed the highest 2,2-diphenyl-1-picrylhydrazy radical scavenging activities. Nitrite scavenging activities of hotwater extracts of G. lingzhi from Korea and China (41% and 39%, respectively) were higher than the activities of 70% ethanol extracts. Total polyphenol contents of hot water extracts of H. erinaceus and C. militaris from Korea were higher than those of 70% ethanol extracts. The ethanol extracts of G. lingzhi from Korea displayed the highest total polyphenol content. C. militaris from Korea displayed the highest ${\beta}-glucan$ level (45.11%). ${\beta}-glucan$ content of H. erinaceus from China (30.87%) was higher than H. erinaceus from Korea (16.94%). The findings indicate that healthy ingredients can be maximally extracted using the optimal solvents for each mushroom. These results will be useful in understanding the difference in physiological activities between the solvents used for the extraction of medicinal mushrooms from Korea and China.

한국과 중국에서 재배한 약용버섯인 노루궁뎅이, 동충하초, 영지의 열수추출물과 70% ethanol 추출물에 대해서 DPPH 라디컬 소거능, 아질산 소거능, 총 폴리페놀 함량, 베타글루칸 함량을 비교하기 위하여 측정하였다. DPPH 라디컬 소거능은 열수추출물과 70% ethanol추출물에서 한국산 노루궁뎅이와 동충하초가 월등히 높았으며, 추출용매별로 비교하였을 경우, 노루궁뎅이와 동충하초는 열수추출물의 항산화효능이 높았다. 아질산염 소거능의 경우, 한국산과 중국산 영지의 열수추출물에서 각각 41%와 39%로 나타나 70% ethanol 추출물에 비하여 높았다. 총 폴리페놀 함량은 한국산 노루궁뎅이와 동충하초는 열수추출물에서 높은 함량을 보였으며, 영지의 경우는 70% ethanol 추출물에서 더 높은 함량치를 나타냈다. 베타글루칸 함량은 한국산 동충하초가 45.11%를 보이며 가장 높았으며, 영지 역시 중국에서 재배한 것에 비하여 높은 함량을 나타냈다. 노루궁뎅이는 중국산이 한국산에 비하여 높은 베타글루칸 함량을 보였다. 위와 같은 결과로부터 각각의 버섯류에 맞는 최적의 용매를 사용해야 최대의 유효성분을 추출할 수 있다고 사료된다. 본 연구에서 사용한 노루궁뎅이, 동충하초, 영지가 한국 및 중국에서 재배되는 버섯의 대표성을 나타내기에는 부족하나 이러한 연구결과를 토대로 더 많은 비교샘플을 확보하여 약용버섯류에 대한 기능성 평가를 위한 기초자료로 활용하고자 한다.
