2-Methoxy-3-methylpyrazine CAS 32737-14-7

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.
