The retention indices (RIs) were calculated using a homologous series of n -alkanes (C8–C22).
b The retention indices (RIs) were from the literature [34 –41 ].
c Results expressed as mean ± standard deviation (
).
d The samples from two regions of China: (A) Guangxi province and (B) Guangdong province.
e Not detected.
f Identified tentatively for the first time as a volatile constituent in A. indianum (Lour.) Merr.
