Santalum Spicatum

Santalum spicatum (R.Br.) A.DC is a West Australian sandalwood species highly valued for the sesquiterpene-rich oil in mature heartwood. The oil composition, particularly levels of the valuable sesquiterpenoids α- and β-santalol and the allergenic E,E-farnesol, are known to vary across its natural distribution. Our study investigated associations of oil characteristics in 186 S. spicatum trees in semiarid and arid regions of Western Australia with genetic structure, environmental parameters and morphological features. We found associations between oil composition and genetic structure, as well as between oil composition and environmental factors. Analysis of individuals using STRUCTURE revealed two major genetic clusters (K = 2), comprising trees from the arid north clustered together, and the semiarid south-west clustered separately. Mantel tests revealed a significant association between oil characteristics and genetic distance (r = 0.129, P = 0.02). There was considerable variation in the growing environment of S. spicatum. An Adonis test showed a significant association between oil composition and provenance (P = 0.001) and between oil composition and soil type (P = 0.002) but not oil composition and other environmental characters. Soil type was significantly related to santalol and E,E-farnesol content. No significant associations between oil composition and morphological features were identified.

Five Artemisia species (seven A. alba Turra samples, and twelve samples of each four remaining species: A. absinthium L., A. annua L., A. vulgaris L., and A. scoparia Waldst. & Kit.) from the Republic of Serbia were studied from the aspect of essential oil chemical composition, and potential correlations between essential oil composition with soil type determined using World Reference Base for Soil Resources (WRB). A great variety in essential oil composition was observed for A. alba, A. absinthium, and A. vulgaris samples, while in the case of A. annua, as well as A. scoparia, the composition of the examined essential oils was more uniform. Principal component analysis (PCA) and Agglomerative Hierarchical Clustering (AHC) showed that there is no significant effect of soil type on the Artemisia essential oil composition while Mantel test showed that there is a correlation between samples within A. vulgaris, as well as A. scoparia and the geographical distances of the localities from which these samples were collected.

Essential oils extracted from basil (Ocimum spp.) by steam distillation are used to flavor foods, oral products, in fragrances, and in traditional medicines. The genus Ocimum contains around 30 species native to the tropics and subtropics, with some species naturalized and/or cultivated in temperate areas. Interand intraspecific hybridization have created significant confusion in the botanical systematics of this genus. Taxonomy of basil (O. basilicum) is also complicated by the existence of numerous varieties, cultivars, and chemotypes within the species that do not differ significantly in morphology. In this study we are using RAPD markers and volatile oil composition to characterize the genetic diversity among the most economically important Ocimum species. We hypothesize that the genetic similarity revealed by molecular markers will more accurately reflect the morphological and chemical differences in Ocimum than essential oil composition per se. Preliminary research using five Ocimum species, four undetermined species, and eight varieties of O. basilicum (a total of 19 accessions) generated 107 polymorphic fragments amplified with 19 primers. RAPDs are able to discriminate between Ocimum species, but show a high degree of similarity between O. basilicum varieties. The genetic distance between nine species and among 55 accessions within the species O. americanum, O. basilicum, O. campechianum, O. × citriodorum, O. gratissimum, O. kilimandscharium, O. minimum, O. selloi, and O. tenuiflorum will be analyzed by matrix of similarity and compared to the volatile oil profile. This research will for the first time apply molecular markers to characterize the genetic diversity of Ocimum associate with volatile oil constituent.

Oil Composition

One of the most important families of Iranian flora is Apiaceae (Umbelliferae). Most of the species of this family are aromatic plants and rich in essential oils with diverse structures. In the present review, the essential oil composition of 63 genera comprising 141 Apiaceae (66.4% native 33.6% endemic) is summarized.

Antimicrobial And Antioxidant Activity

Objective: Ziziphora clinopodioides is an edible medicinal plant belongs to the Labiatae family that widespread all over Iran. It used as culinary and also in cold and cough treatments in Iran. The aim of present work was to evaluate the effect of different timeframes during the hydrodistillation on essential oil composition, antimicrobial and antioxidant activity. Materials and Methods: The essential oil of Z. clinopodiodes was extracted via hydrodistillation with Clevenger apparatus. The fractions of essential oil were captured at 6 times from the beginning of the distillation: (10, 20, 60, 120, 180 and 240 min). The fractions of essential oil were analyzed by GC/MS and their antibacterial, antifungal and antioxidant activities were studied by Disk - well diffusion and DPPH methods respectively. Results: Six distillation times and whole essential oil were captured during the hydrodistillation. Essential oil yield dropped off significantly during distillation progressed (1.0% for 10 min and 0.025 for 240 min). 1,8 Cineol, Isomenthone, Pulegone, Piperitenone and Citronellic acid were major compounds in fractions and they were affected by distillation times. Pulegone was major compound in all of essential oils. In antioxidant activity assay, whole essential oil was stronger than was stronger than positive control and fractions of essential oil, because of higher levels of Isomenthone, Piperitenone and Citronellic acid. Strongest antimicrobial activity against S. aureus, E. coli and C. albicans was observed from 10 min fraction. Conclusion: Our results indicated that distillation time can create essential oils with specific properties and we can achieve to more efficient essential oil in short times.
