Mushrooms are valued as a nutritional food and also as an important source of useful medicinal components. They produce various secondary metabolites which have interesting biological activities and unique chemical structures. As part of our ongoing investigation on chemical constituents and bioactive components of Korean native mushrooms, compound 1, an indole alkaloid, was isolated from the fruiting body of Boletus umbriniporus. B. umbriniporus is characterized by its yellow flesh, which changes to pallid blue when exposed to air, and its chemical constituent has not been reported. Chemical structure of compound 1 was determined to be flazin on the basis of ESI-mass, $^1H$ NMR, $^{13}C$ NMR, $^1H-^1H$ COSY, HMQC, and HMBC analysis. This compound was isolated from the fruiting body of B. umbriniporus for the first time. 우리나라 자생 버섯에 함유된 화학적 구성성분을 조사하던 중 암갈색그물버섯에서 indole alkaloid 화합물을 분리하고 mass 및 NMR 분석을 통하여 화학구조를 flazin으로 동정하였다. 비록 Flazin 화합물이 젖비단그물버섯에서 분리되어 보고된 적은 있으나 본 연구에 의하여 암갈색그물버섯에도 flazin 성분을 함유하고 있음이 처음으로 밝혀졌다.

In the course of search for multifunctional microbial inoculants, three Bacillus strains (BS11-1,BS11-2,BS11-3) with biological control and biofertilizing effects were selected. In this study, their ability for solubilization of insoluble phosphate, production of indole-3-acetic acid (IAA), siderophore, and hydrolytic enzymes, and antagonism against phytopathogenic fungi were estimated. All strains produced IAA and siderophore depending on culture time and produced a visible clear zone on agar plate containing 0.5% carboxylmethyl cellulose as a carbon source. Also, these strains exhibited antifungal activities against phytopathogenic fungi, Botrytis cinerea, Cylindrocarpon destructans, Fusarium oxysporum, Rhizoctonia solani, and Phytophthora capsici.
