Chemical investigation of the secondary metabolites of the whole plant of bryophyte Hypnum plumaeforme Wilson led to the isolation of a new pimarane‐type diterpenoid, momilactone F (1), along with seventeen known compounds. Their chemical structures were elucidated based on massive spectroscopic data. The allelopathic and antifungal properties were evaluated. Among them, momilactone F (1), acrenol (2),[11] momilactones A (3) and B (4) showed significant allelopathic activity against Samolus parviflorus Raf. and Lactuca sativa L. var. angustana Irish, as well as selected antifungal property against crop pathogenic fungi strains. On the other hand, 8(14)‐podocarpen‐13‐on‐18‐oic acid (8) exhibited strong promoting activity on the growth of L. sativa L. var. angustana Irish. The present investigation provided new insights for developing of H. plumaeforme for further application as a potential agricultural tool.

来自苔藓植物 Hypnum purgeeforme Wilson 的生物代谢物

对苔藓植物 Hypnum splasheforme Wilson 全株次生代谢物的化学研究导致分离出一种新的海莨菪碱型二萜类化合物莫米内酯 F (1) 以及 17 种已知化合物。基于大量光谱数据阐明了它们的化学结构。评价化感作用和抗真菌特性。其中，momilactone F (1)、acrenol (2)、[11] momilactones A (3) 和 B (4) 对Samolus parviflorus Raf 表现出显着的化感作用。和 Lactuca sativa L. var。angustana Irish，以及针对作物病原真菌菌株的选定抗真菌特性。另一方面，8(14)-podocarpen-13-on-18-oic acid (8) 对 L. sativa L. var. 的生长表现出强烈的促进活性。安古斯塔纳爱尔兰人。本研究为 H.
