Iristectorone K, a novel monocyclic triterpene ester from Iris germanica rhizomes growing in Turkey.

A new monocyclic triterpene ester (1) was isolated from the rhizomes of Iris germanica from Turkey. Structure elucidation of compound (1) was carried out by the combined application of HMQC, HMBC, DEPT, COSY and NOESY experiments and named as iristectorone K.

Full Blooming Stage is Suitable for Herbage Yield and Essential Oil Content of Summer Savory (Satureja hortensis L.)

Abstract The study reports determination of appropriate development stage, its effects on herbage yield and essential oil content compositions of summer savory (Satureja hortensis L). The essential oil of summer savory was isolated by steam distillation and analysed by GC-MS. The results indicated that the highest dry leaf yield, fresh and dry herbage yield were obtained at post and full blooming stage. However, the highest essential oil content of 2.6 % was obtained at full blooming stage. Major essential oil components of summer savory were determined as thymol, γ-terpinene, carvacrol and cymol in ratio of 47.9, 19.6, 14.7 and 9.7 %, respectively. Thymol percentage increased at post harvest stage, in contrast to γ-terpinene. The results suggest that to achieve maximum oil yield for profitable income harvest should be done at full blooming stage.

Domestication and Determination of Yield and Quality Aspects of WildMenthaSpecies Growing in Southern Turkey

Menthaspecies are cultivated in many countries commercially because of their valuable essential oil. Mint, which has anti-spasmatic, carminative, gastral, stimulating, and diuretic effects has been grown as a spice and curative plant. Mint oil is the richest natural source of menthol, which is widely used in medicine, food and cosmetics industry1,2.
