Abstract

The essential oil from leaves of Pistacia lentiscus L., an aromatic member of three Pistacia (Pistacia Vera L.) cultivars, including Kalle Ghoochi, Akbari, and Sefid that were analyzed by GC-MS. These Pistacia species have been collected from Khorasan Razavi, Iran. Constituents were identified by their mass spectra and Kovats’ indices. Pistacia1,8-cineole, α-pinene, β-pinene, β-thujene, and limonene were found to be the major constituents.

Abstract

Taximetric statistical methods were carried out on morpho-agronomic traits from three Manila hemp (Philippine abaca) varieties planted in three locations in Southern Mindanao, Philippines. Principal Component analysis (PCA) resulted in the extraction of five principal components which collectively accounted for 99.85% of total variance. Continue reading
