The active compound from Clerodendrum paniculatum leaf was obtained with induction activity to systemic resistance of cucumber mosaic virus (CMV) to red chilli.
Methanol extract of Clerodendrum paniculatum leaf was concentrated and extracted with ethyl acetate. Ethyl acetate extract shows induction activity with inhibition percentage above of 55%. Ethyl acetate extract was separated with column chromatography using kieselgel 60 provide one of compound as white needle crystal with 146-148oC melting point. Based on phytochemistry test and spectroscopy data including : IR, 1H-NMR, 13C-NMR and 2D NMR as well as comparation with literature data was concluded isolated compound was steroid group. The inhibition compound showed 87% inhibition activity to red chilli plants from (CMV) at 300 ppm of concentration.
