摘要：

Three new lanostane type triterpenes have been isolated from the bark of Neolitsea sericea. Their structures were established as 24Z-ethylidenelanost-8-en-3-one, 24-methylenelanost-8-en-3-one and 24Z-ethylidenelanost-8-en-3 beta-ol by spectral analyses. In addition other known compounds, 24-methylenelanost-8-en-3 beta-ol and sitosterol were also isolated. 24Z-Ethylidenelanost-8-en-3-one and 24-methylenelanost-8-en-3-one had moderate activity against mites.
