Furthermore, some researchers have found plumbagin extracted from roots of this species can prevent cancer cell development. In current study, stems of Plumbago zeylanica L. were cultured on MS medium with BA 1.0 mg/L and IAA (0.01-0.15 mg/L) or NAA (0.1-0.15 mg/L). After 8-week cultured, stems were transferred to MS medium with extracted from stems of Portulaca grandiflora Hook (2-10 ml/L) or extracted from stems of Ipomoea batatas (L.) Poir. The results showed that, the appropriate medium for shoot formation was in MS with BA and IAA 0.1 mg/L or NAA 0.1 mg/L.
