title: Volatiles of Lysimachia paridiformis Var. Stenophylla, Lysimachia fortumei and Lysimachia chikungensis by HS-SPME-GC-MS.
abstract: 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.
  
  
  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%).
  
  
  CONCLUSIONS
  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.
