A new marker system for neem oil
Caijun Zhang
Terramera Inc., Canada
Statement of the Problem:
Neem oil contains more than 100 biologically active compounds (limonoids). Azadirachtin as a
marker for neem oil is well adopted in the biopesticide industry. However, this marker is insufficient to distinguish whether
the neem oil is contaminated with other botanical oil because azadirachtin (A and B) represent only the polar and hydrophilic
limonoids, very small portion of bioactive ingredients in neem oil.
Methodology & Theoretical Orientation:
Terramera develop a finger-print HPLC method which can detect most bioactive
ingredients in neem oil. According to the HPLC profile, a new marker system was developed in Terramera. This new marker
system includes a wider spectrum of active ingredients and can protect from the adulterated neem oil because any foreign
peaks can be easily detected under other limonoids region
Conclusion & Significance:
The new marker system for neem oil provides a much better representation of the quality of neem
oil than measuring azadirachtin alone.
