From the petroleum ether extract of the fresh roots of A. flabellata, a cyclohexene derivative, alflabene (112) was isolated and identified on the basis of its spectral properties and by synthesis [73]. The same compound was also isolated from the rhizomes of Zingiber cassumunar.

The compounds (63) and (64) were identified ( 1%) in Phlai Zingiber cassumunar Roxb.) 334). Furthermore, (63) was isolated from nutmeg oil Myristica fragrans Houttyn) 24 and (64) was also identified in Hinoki oil 640) and raspberries 707). The three allyl alcohols (65), (66) and (68) were detected for the first time in gingergrass oil 423, 532). 

Several thujane derivatives were found to be important components in a series of flavor-producing plants. Sabinene (112) was identified as the major constituent of Phlai Zingiber cassumunar Roxb.) (33.4%) 334) and of nutmeg oil Myristica fragrans Houttyn) 24, 266 especially in the West Indian spice of Granada origin in which it is present in amounts of up to 50%.
