摘要：In order to add a new species of medicinal and aromatic plants to be cultivated in Egypt for export we decided to study the plant of Nepeta cataria L, by identifying the best ways to increase the proportion of seed germination, vegetative measurements and identify productivity of essential oil. Seeds germination of Nepeta cataria L plant as affected by the kind of soil germination and date of sowing were studied. Preparing seeds nursery was carried out using three different types of agricultural soil. The first one was a pure sandy soil (S1), the second was a mixture of sand and clay loamy soil (S2) in the ratio of (1: 1), while the third included a mixture of sand and clay loamy soil (S3), in the ratio of (2: 1). It is clear from the results that the soil type and sowing time treatments had significantly affected germination percentage. Using S3 treatment gave the best result particularly when the seeds were sowed during February in the two seasons. The growth measurements of Nepeta cataria plants during the growing season under the Egyptian environment showed that, the fresh yield of N. cataria herb recorded 138.5 and 180.0 gms / plant in the first and second cut, respectively. The highest percentage of oil recorded (0.25%) during the first cut, against (0.19 %) in the second cut. Analysis of Nepeta cataria oil indicated that, the volatile oil of .N. cataria L from Egypt is rich in citral, geraniol, and nepetalactone. The oxygenated monoterpenes compounds were found as the main composition of essential oil of catmint oil (70.75 and 81.55 % in the first and second cut, respectively). Citral and nepetalactone were found as the main compounds of oxygenated monoterpenes group in catmint oil cultivated in Egypt.
