Abstract
The present investigation was carried out during the two successive seasons of 2002 and 2003 on marigold plant (Tagetes minuta, L.) at the Experimental Station of Medicinal and Aromatic Plants, Fac. of Agric., Mansoura Univ.
This work aimed to study the possibility of using spraying active dry yeast at the concentrations of 0, 1, 2 and 3 gIL applied three times to improve growth and yield parameters as well as the oil percentage and oil yield per plant. Also, to study the effect of length of the storage period of the dried herbs on essential oil percentage and its constituent.
The results showed that although all the treatments improved the growth and yield parameters, active dry yeast at the rate of 3 gIL proved to be the most favorable as increases in both fresh and dry herb yields per plant, as well as the oil percentage and oil yield per plant were achieved. Regarding storage period, the results also showed that increasing the storage period of the dried herbs resulted in reduction of the essential oil percentage. Gas Liquid Chromatography analysis of oil samples revealed seven identified compounds. Storage period had a clear effect on the chemical composition of the extracted marigold oil, since some of the principle components increased such as limonen and cis-tagetone as the storage period increased, while those of dihydrotagetone and ~-pinene decreased over the same period compared with the control.
