Background: Lysimachia paridiformis
Var.
Stenophylla mainly contain flavonoid constituents. Flavonoids and benzoquinones are the main
compounds in
L. fortumei Maxim. The objective of this paper was to study the volatile compounds of leaves in
L. paridiformis Var.
Stenophylla,
L.
fortumei and
L. chikungensis
for the first time.
Materials and Methods: Volatiles were extracted by the manual solid phase micro-extraction (SPME). The volatile constituents were analyzed
by an Agilent 6890 N gas chromatograph equipped and coupled with a 5975B mass selective detector spectrometer.
Results: Twenty-nine compounds were identified in the leaves of
L. paridiformis var.
Stenophylla, accounting for 89.17% of the total volatile
fraction. The main constituents were ethanol (13.58%), and
β-ionone (8.05%). linalool and
β-ionone were the main aroma constituents in
L.
paridiformis var.
Stenophylla. Twenty-one compounds were identified in the leaves of
L. fortumei, accounting for 94.72% of the total volatile
fraction. The main constituents were tricosane (14.72%), docosane (11.02%), tetracosane (10.77%) and pentacosane (9.81%). Thirty-two
compounds were identified in the leaves of
L. chikungensis, accounting for 88.58% of the total volatile fraction. Typical compounds detected in
L.
chikungensis were
cis-3-hexenyl pentanoate (13.33%), followed by ethanol (12.13%), ethyl palmitate (7.78%), and heneicosane (5.38%).
Conclusion: The results showed that the main composition types were similar in the three plants, but the content was different, which indicated
that the similar composition types provided the same medical effect for three plants.
