| "Rhizoma Alpiniae Officinarum (RAO), the dry root and rhizome of Alpinia officinarum Hance, is a traditional Chinese medicine (TCM) mainly distributed in southern China. RAO has long been used in practice for its antioxidation, antidiabetic, anti-ulcer, anti-diarrhea, antiemetic, analgesia, anti-inflammatory and anticoagulation effects... Flavonoids, volatile components and diarylheptanoids are reported as the main constituents of RAO and volatile components contribute a lot to those bioactivities. \\ | "Rhizoma Alpiniae Officinarum (RAO), the dry root and rhizome of Alpinia officinarum Hance, is a traditional Chinese medicine (TCM) mainly distributed in southern China.

Flavonoids, volatile components and diarylheptanoids are reported as the main constituents of RAO and volatile components contribute a lot to those bioactivities. \\ |
| Main compounds [of RAO, extracted by hydrodistillation] were presented as follows: α-farnesene (19.68%), γ-muurolene (13.33%), p-menth-1-en-8-ol (10.16%), eucalyptol (6.00%), 2,6-dimethyl-6-(4-methyl-3-pentenyl)bicyclo[3.1.1]hept-2-ene (5.01%), isocaryophillene (3.97%), cadinol (3.23%), cadina-1(10),4-diene (3.21%) and caryophyllene (2.76%). \\ | Main compounds [of RAO, extracted by hydrodistillation] were presented as follows: α-farnesene (19.68%), γ-muurolene (13.33%), p-menth-1-en-8-ol ([alpha-terpineol] 10.16%), eucalyptol (6.00%), 2,6-dimethyl-6-(4-methyl-3-pentenyl)bicyclo[3.1.1]hept-2-ene (5.01%), isocaryophillene (3.97%), cadinol (3.23%), cadina-1(10),4-diene (3.21%) and caryophyllene (2.76%). \\ |
| Thirty-two volatile compounds from RAO [extracted by HS-SPME] were identified by GC/MS. Their peak areas occupied 91.02% of the total and the major components included α-farnesene (25.37%), γ-muurolene (14.02%), eucalyptol (7.59%), 2,6-dimethyl-6-(4-methyl-3-pentenyl)bicy- clo[3.1.1]hept-2-ene (7.05%), p-menth-1-en-8-ol (6.68%), isocaryophillene (4.35%), cadina-1 (10),4-diene (3.89%), caryophyllene (3.05%) and (Z,Z,Z)-1,5,9,9-tetramethyl-1,4,7-cyclound-ecatriene (2.73%)." \\ | Thirty-two volatile compounds from RAO [extracted by HS-SPME] were identified by GC/MS.
