Essential oil from steam distilled whole plants of basil, Ocimum basilicum L., cv. Large Green, harvested with different flower sizes was compared with oil produced from basil flowers only. Higher yields were obtained when distilling basil with long flower spikes (12 to 20 cm) rather than with shorter flower spikes. Distilling the whole plant gave an oil with a higher percentage of methyl chavicol whereas the flower spikes produced an oil richer in linalool.
