Essential oils may be extracted from seeds by hydro-distillation, using a Clevenger-type apparatus. Yield of essential oil varies from 1-2% depending upon variety and season.
Karen A. Darbinyan thank you sir for this paper. But I actually wanted the essential oil yield/percentage of basil SEEDS and not the leaves. In this review they extracted oil from leaves only.
Suresh K Malhotra Thank you sir for your answer, can you please attach or recommend any reference. Actually I have tried to find some work done, but failed to do so.
