Examination of the leaves of Zanthoxylum integrifoliolum led to the isolation of a new bishordeninyl alkaloid, integramine, along with alfileramine, α‐allocryptopine, pseudoprotopine and (+)‐sesamin from the tertiary non‐phenolic base fraction. The structures of these compounds were elucidated by spectral evidence. 相似文献

Anew sesquiterpenoid, α‐santalane‐11,12,13‐triol, together with thirty known compounds were isolated and characterized from the root bark of Severinia buxifolia in Hainan. Their structures were determined by spectroscopic methods. The relationship between constituents and collecting area is also discussed. 相似文献

Two new phenylpropanoids, integrifoliolin ( 1 ) and integrifoliodiol ( 2 ), together with 23 known compounds, have been isolated from the root wood of Zanthoxylum integrifoliolum. The structures of these compounds were determined by means of spectral analyses. The reported anti‐HIV constituents of decarine and γ‐fagarine were also isolated from the root wood of this plant. 相似文献

The volatile fractions of the petroleum ether extract and of the alkaloid extract ofHaplophyllum myrtifoliumBoiss., endemic to Turkey, were trapped by using the Solid Phase Micro Extraction (SPME) technique and analyzed by GC/MS. Forty-seven compounds were characterized from the petroleum ether extract of the aerial parts with -caryophyllene (14.6 %), decane (11.4 %), and -phellandrene (7.0 %) as the major components. Chavibetol (21.9 %), eugenol (19.1 %), methyleugenol (10.8 %), trans-linalool oxide (7.1 %) and -cyclocitral (6.0 %) were identified as the major components among the forty-two compounds characterized in the chloroform eluate of the alkaloid extract. 相似文献

cis‐Fagaramide ( 1 ), a new amide, together with fifty known compounds, have been isolated from the leaves of Zanthoxylum schinifolium. These known compounds include twenty‐one coumarins, eleven alkaloids, one furan, four benzenoids, three chlorophylls, four triterpenoids, one diterpenoid, one sesquiterpenoid, and four steroids. The structures of these compounds were determined by means of spectral analyses. 相似文献
