Pogostemon cablin (Blanco) Benth Made from dried leaves. It is a viscous liquid ranging from reddish brown to greenish brown, with a unique, slightly camphor like woody fragrance.The patchouli shrub is mainly planted in Indonesia. It grows up to 1 meter, but when harvested, it will be cut to 10-15 centimeters. It is best to extract oil from sun dried leaves, with a yield of about 2%.The three terpenoids found in patchouli oil, namely caryophyllene, patchouli alcohol or patchouli alcohol, and nopachenol, are the typical sources of patchouli fragrance. Thin layer chromatography and high performance liquid chromatography are used to identify potential chemical markers for evaluating the quality of the Chinese herbal medicine ingredient ??patchouli herb?? (aboveground part of patchouli). In addition to the reported patchouli alcohol and 2-hydroxy-6-methyl-3- (4-methylpentanoyl) -4-pyranone, three phenylethane compounds (acteoside, isoacteoside, and crenatoside) were also isolated from this plant material for the first time.

Cis ?C 3-Methyl-4-octanolide, also known as cis- ??- methyl- ??- Octalactone or 5-butyldihydro-4-methylfuran-2 (3 H) ?C one, a compound of lactone family, chemical formula C9H16O2. It exists as two optical isomers: 3 R, 4 R (??+??) and 3 S, 4 S (??-??).

3S, 4S isomers, commonly known as whisky lactone or oak lactone, are important components in the aroma of whisky (first discovered by Suomalainen and Nyk ? nen in 1970) and other alcoholic beverages aged in oak barrels. It is sometimes added to wine as a flavoring. It has the aroma of coconut, celery or fresh wood, and can be detected by human body when the concentration in the air is 1 microgram/l. The mixture of cis and trans isomers can repel mosquitoes and flies.
