Abstract: | Castasterone (1), teasterone (2), and 6-deoxocastasterone (3), as well as monoolein, monolinolein, and monopalmitin, have been identified in immature seeds of rice (Oryza sativa) as active principles in the rice lamina inclination bioassay. Castasterone, as well as monoolein and monopalmitin, were likewise identified in immature seeds of Perilla frutescens, while monopalmitin was identified as a major active principle in cultured cells of Nicotiana tabacum. It seems that the occurrence of monoglycerides in higher plants as biologically active principles might be a general feature. |
