| Summary: | Stemona
plants (Stemonaceae) have been traditionally used as natural pesticides and medicinal plants.
S. curtisii
, the dominant species distributed in the South and Southwest of Thailand, has been of interest for its insecticidal properties. Variation of active components affects their promised biological effects. Therefore, the study of variability of the contents of its bioactive components was done. Ten samples of
S. curtisii
were collected from various locations of Thailand. Each dried sample was exhaustively extracted with methanol by sonication and the extract was analyzed by the validated HPLC method. The contents of oxystemokerrine (
1
), stemocurtisine (
2
), stemocurtisinol (
3
), and stemofoline (
4
) in dried powder of
S. curtisii
roots were calculated. A remarkable variation of alkaloids profile was observed in different geographical provenances of
S. curtisii
in Thailand. This study would provide a basis for standardization of
S. curtisii
raw materials for a better source and for further insecticidal development. |
