Turkey has a very rich fungal flora due to its phytogeographical position. The screening of chemical content and active substances of mushrooms becomes an important subject not only for Turkey but also for all over the world. In the last decade, Analyses on phytochemical and biological activity of fungi have gradually increased as a result of improvement in the number and quality of facilities. In the scope of the present research, four medicinal mushrooms; Morchella elata, Lactarius volemus, Cantharellus cibarius and Tricholoma terreum were analyzed for their fatty acid compositions and antioxidant capacities. The fungal species have been found with unsaturated fatty acid/saturated fatty acid ratio of 6.73 for Morchella elata, 4.12 for Lactarius volemus, 5.21 for Cantharellus cibarius, 3.73 for Tricholama terrum. In addition, the concentration of malondialdehyde which was an indicator of lipid peroxidation was also determined in these species. According to the results, free radical scavenging activity of Morchella elata and Lactarius volemus were found higher than the other species. Any of the mushroom species investigated were found having very high metal chelating activity. The results showed that the extract of Morchella elata and Lactarius volemus exhibited significant antioxidant activities. Hence, the mushrooms have a potential to be a natural antioxidant in food industries as antioxidant agent.

Mushrooms have a long history of use in traditional medicine, and hundreds of novel constituents in mushrooms with miraculous biological properties have been identified recently. Although diverse effects for medicinal use of mushrooms such as anticancer activity are proven, their reversal activities of drug resistance in cancer cells was rarely reported so far. In the search for novel medicinal use of mushrooms, we tested the multidrug resistance (MDR) reversal activities of diverse mushrooms collected from Korea. Among, the mushroom extracts tested, Cantharellus cibarius (M02) and Russula emetica (M12) revealed MDR reversal activities of paclitaxel in the P-glycoprotein (Pgp)-positive HCT15 and MES-SA/dX5 cancer cells, but not in the Pgp-negative A549 and MES-SA cancer cells. In addition, these mushrooms also enhanced the cytotoxicity of doxorubicin, another well-kwown Pgp-associated anticancer drug against MES-SA/DX5 cells, but not against MES-SA cells. Meanwhile, the cytotoxicity of cisplatin, a well-known Pgp-non-associated anticancer drug, was not affected by the mushrooms all the cells tested. From these results, we suspected that some ingredients of M02 and M12 have Pgp-associated MDR reversal activities.

외생균근(外生菌根)버섯의 기주범위(寄主範圍)와 기주선택성(寄主選擇注)을 구명(究明)하고 주요(主要) 조림수종(造林樹種)의 균근균(菌根菌) 선택성(選擇性)을 상호비교(相互比較)하기 위하여 1981년(年)부터 1986년(年)까지 전국(全國)의 여러 곳에서 12개수종(個樹種)의 순림(純林)(소나무, 리기다소나무, 잣나무, 종비나무, 일본잎갈나무, 젓나무, 현사시, 밤나무, 갈참나무, 상수리나무, 신갈나무, 자작나무)를 대상(對象)으로 균근(菌根)버섯을 채집(採集)하여 분석(分析)을 비교(比較)하였다. 6년(年)동안 총(總) 48리(履) 196종(種) 8 품종(品種)의 균근(菌根) 버섯을 동정(同定)하였으며 그 중 Russla가 31종(種) 1 품종(品種), Amanita가 22종(種) 5 품종(品種), Lactarius가 18종(種) 1 품종(品種)이었다. 기주범위(寄主範圍)가 넓은 종(種)은 Russula, Amanita, Lactarius, Laccaria, Cantharellus 속(屬)에 속(屬)해 있있다. Laccaria Laccata는 12개조사수종중(個調査樹種中)에서 12개수종전분의 임분(林分)에서, Amanita vaginata group은 11개수종(個樹種)에서, Labtarius gerardii와 Russula sororia는 9 개수종(個樹種)에 서, Amanita agglutinata, Cantharellus cibarius, Russula bella, Russula bella, Russula virescens는 8개수종(個樹種)의 침개엽수임분(針開葉樹林分)에서 채집(採集)되어 기주(寄主)의 범위(範圍)가 넓은 버섯으로 분류(分類)되었다. Amanita citrina, Boletus bicolor, Boletus erythropus, Lactarius piperatus, L. subzonarius, Russula pseudodelica는 침개활수(針葉闊樹)의 $4{\sim}5$개수종(個樹種)에서 채집(採集)되어 기주(寄主)의 범위(範圍)가 중간(中間)정도(程度)인 버섯으로 분류(分類)되었으며 특히 Suillus grevillei는 잎갈나무에서서만 채집(採集)되어 기주(寄主)의 범위(範圍)가 가장 좁은 버섯으로 판명(判明)되었다. 12개수종(個樹種)의 임분중(林分中)에서 균근(菌根)버섯의 종류(種類)가 가장 많은 젓나무림(林)으로써 83종(重)의 균근(菌根)버섯을 채집(採集)했으며, 소나무(赤松)림(林)에서 66종(重)을, 리기다소나무림(林)에서 50종(種)을, 잣나무림(林)에서 49종(重)을, 갈참나무림(林)에서 46종(種)을 채집(採集)했다. 일본잎갈나무림(林)에서는 23종(種)의 균근(菌根)버섯을 채집(採集)했는데 다른 임분(林分)과 달리 Amanita, Lactarius, Russula 는 적고 대신 Laccaria 가 많이 관찰(觀察)되었다. 본(本) 실험(實驗)에서 조사(調査)된 12개수종(個樹種)의 대부분(大部分)은 다양(多樣)한 균근(菌根)버섯과 공생(共生)하는 듯하며 균선택성(菌選擇性)이 적은 것으로 사료(思料)된다.
