Improving the efficiency of essential-oil extraction from Abies sachalinensis with an underwater shockwave pretreatment
Abies sachalinensis (Sakhalin fir) is a conifer species belonging to the family Pinaceae that is native to and widely distributed throughout Sakhalin Island, the southern Kurils (Russia), and northern Hokkaido (Japan). The essential oil of A. sachalinensis has been found to be an active removal agen...

Abies sachalinensis (Sakhalin fir) is a conifer species belonging to the family Pinaceae that is native to and widely distributed throughout Sakhalin Island, the southern Kurils (Russia), and northern Hokkaido (Japan).
