| 中文摘要: |
| 洱源丛枝瑚（Ramaria eryuanensis）石油醚萃取物经过柱层析得到单体化合物B8，该化合物对小菜蛾3龄幼虫72 h的LC50为3.375 7 mg/mL。经FAB-MS、1HNMR、13CNMR及DEPT等波谱鉴定，并与文献值对照，确定其为麦角甾-7,22-二烯-3β,5α,6β-三醇。 |
| 英文摘要: |
| The petroleum ether extract of Ramaria eryuanensis was isolated and purified through normal pressure silica gel pillar chromatography, and one compound was obtained. The LC50 value of the compound against the 3rd instar larvae of Plutella xylostella in 72 h was 3.375 7 mg/mL. The molecular structure was identified by FAB-MS, 1HNMR, 13CNMR and DEPT as ergosta-7,22-dien-3β,5α,6β-triol. |
