Santalum album (+)-alpha-terpineol + diphosphate products are 44% (+)-alpha-terpineol and 33.6% (-)-limonene, along with small quantities of linalool, myrcene, alpha-pinene, (+)-sabinene and geraniol ?
4.2.3.126 (2E,6E)-farnesyl diphosphate
-
Santalum album gamma-muurolene + diphosphate SasesquiTPS1 with (2E,6E)-farnesyl diphosphate as substrate produces a complex mixture of mono- and bicyclic sesquiterpenes. The main products as analysed by GC-MS and GC-FID are the cyclic alcohol germacrene D-4-ol, and helminthogermacrene. Also present are alpha-bulnesene, gamma-muurolene, alpha- and beta-selinenes, as well as several other minor bicyclic compounds, alpha-humulene and nerolidol are detected in proportions below 5% ?
