Cinnamomum longepaniculatum

Cinnamomum longepaniculatum N. Chao ex El.W. Ei leave EO Micromeria fmticosa E. Druce ssp. 

This is a very simple method to stretch. Clove leaves are easier to harvest and bring similar oil as the stem or bud oil. Clove bud oil is nearly three times higher in price than clove leaf oil. Therewith the concocting of that oil makes sense. Pimento berry oil and leaf oil are closely related in composition. The price of the berry oil is double the leaf oil consequently, adulteration is interesting. By GC-MS method and regarding minor components, this immixture will be detected. Eucalyptus oil from China is derived from Cinnamomum longepaniculatum (Gamble) 1,8-cineole type. Either the whole oil sold as eucalyptus oil or Eucalyptus sp. added is clearly not allowed and must be seen as adulteration. 

ISO standard 770 shows character and data for this oil. Schmidt (2010) reported the Chinese eucalyptus oil coming from Sichuan province and is derived from C. longepaniculatum (Gamble). This must be labeled and it is not correct to mix this up with true eucalyptus varieties. Adulteration is done by 1,8-cineole from various Cinnamomum varieties. The detection is not easy as all these adulterations are natural.
