Strain DCS523 was isolated from the branch tissue of Daphniphyllum longeracemosum and determined to be a Penicillium sp. according to the ITS sequence analysis. The extracts from the PDA solid fermentation media of Penicillium sp. DCS523 were purified to give two new chroman derivatives as well as six known compounds. Based on their spectral data the new compounds were identified as (Z)-6-acetyl- 3-(1,2-dihydroxypropylidene)-5-hydroxy-8-methylchroman-2-one and 6-acetyl-2α,5- dihydroxy-2-(2-hydroxypropyl)- 3α,8-dimethylchroman, respectively.
菌株 DCS523 从长枝木莲叶的枝条组织中分离出来，根据 ITS 序列分析确定为青霉属。从青霉属 DCS523 的 PDA 固体发酵培养基提取物中分离得到两种新的色满衍生物和六种已知化合物。根据其光谱数据，新化合物分别鉴定为（Z）-6-乙酰基-3-（1,2-二羟丙基）-5-羟基-8-甲基色满-2-酮和 6-乙酰基-2α,5-二羟基-2-（2-羟丙基）-3α,8-二甲基色满。
