Abstract
Two different groups of natural products with growth promoting activity were extracted from the pink and white flowered variety of Lantana camara L. One was a gibberellin-like compound with a molecular weight of 468 and m. p. of 227.5 ⁰C while the other was a phytosterol with molecular weight of 430 and melting point 98.8⁰C. The two fractions in combination, acted synergistically and positively influenced the growth and yield of rice.
