“…One of the two samples previously analysed belongs obviously to cluster I (1,8-cineole 36.3%), while the second sample should be classified into cluster II (β-pinene 16.0% and trans-pinocarveol 9.3%). 12 The chemical composition of the samples from the Tlemcen province of Algeria (both clusters) differed obviously from those reported for samples from Saudi Arabia and from some samples from Morocco, in which camphor or borneol were reported as the main components. 8,9 These two components represented less than 2.2% of the chemical composition of any sample reported in the present study.…”

“…Otherwise, the composition of the oil exhibited only small variations during the life cycle of the plant. 12 In the present study, we prepared and analysed (using GC-RI and 13 C-NMR) 55 samples from individual plants and submitted the results to statistical analysis in order to describe more precisely the infraspecific chemical variability of the essential oil of L. dentata var. dentata from Tlemcen Province (Algeria).…”

Fifty-five samples of essential oil obtained from individual plants of Lavandula dentata L. var. dentata from Algeria were analysed using GC and 13 C-NMR spectroscopy. The results were submitted to chemometric analysis (k-means clustering and principal component analysis). Two principal clusters of equal importance were distinguished within the essential oil of the individuals of L. dentata. The samples belonging to cluster I were characterized by a very high content of 1,8-cineole (mean value 48%). Conversely, the mean composition of the samples of cluster II were dominated by 1,8-cineole, β β β β β-pinene, trans-pinocarveol and linalool.

“…The contents of the constituents found in this work differ from those found in literature, which also vary among L. dentata plant-producing regions. In Algeria, the major compounds were 1,8-cineol, β-pinene, trans-pinocarveol and linalool (Bousmaha et al, 2005). In Morocco, the relative concentrations of betapinene, mirthenol and alpha-pinene were higher (Imelouane et al, 2010), while in Egypt other major constituents were found, as menta-1,5-dien-8-ol, caryophyllene, guiaol (Abdel-Hady et al, 2014).…”

“…Several compounds were cited as major components in lavender essential oil in plants grown in Algeria, Saudi Arabia, Spain, Morocco and Turkey: 1,8 cineole, camphor, borneol, fenchol, α-pinene, β-pinene, trans-pinocarol and linalool (Bousmaha et al, 2005…”

“…Among these, some have antibacterial and antifungal properties (Aly et al, 2013), antioxidants and citotoxicity (Imelouane et al, 2010;Abdel-Hady et al, 2014). The composition and the relative proportion of the individual components constituting the essential oils are not constant, may vary according to the harvest times, the development stage of the plant and the different part of the plant (Bousmaha et al, 2005). According to Zheljazkov et al (2013), the chemotype of the plant changes according to interactions with the environment such as temperature and solar radiation.…”

Selection of processing tomato genotypes resistant to two spotted spider mite

One of the major problems in cultivation of tomato is the occurrence of pests and diseases. The objective of the research was to select genotypes from the second generation of the first backcross (F2BC1) between the tomato cultivar for processing S. lycopersicum (cv. Redenção) and the wild access S. habrochaites var. hirsutum (PI-127826), with high levels of zingiberene (ZGB), resistant to the twospotted spider mite Tetranychus urticae (Acari: Tetranychidae). From the F2BC1 population. The ZGB content was quantified and five plants with high zingiberene selected (RVTZ 2011-079-117, RVTZ 2011-079-185, RVTZ 2011-079-335, RVTZ 2011-079-345 and RVTZ 2011-079-503) and four with low zingiberene content (RVTZ 2011-079-417, RVTZ 2011-331-460, RVTZ 2011-079-538 and RVTZ 2011-079-548) were selected. Genotypes selected for high and low ZGB content and the parentals S. habrochaites var. hirsutum access PI-127826 and ‘Redenção’ were evaluated for repellency to the twospotted spider mite. There was a significant and inverse correlation between ZGB content and average distances travelled by mites on tomato leaflets. The genotypes of the F2BC1 generation with high zingiberene levels RVTZ 2011-079-117, RVTZ 2011-079-185, RVTZ 2011-079-335, RVTZ 2011-079-345 and RVTZ 2011-079-503 are promising for progress in achieving resistant lines to arthropod pests. Among them RVTZ 2011-079-117 stands out for resistance to twospotted spider mite.

This study presented a micromorphological and phytochemical survey on Lavandula dentata L. cultivated at the Ghirardi Botanic Garden (Toscolano Maderno, BS, Italy). The morphological investigation revealed the presence of peltate, short-and medium-stalked capitate trichomes. The histochemical survey showed terpene production by peltates and medium-stalked capitates, hydrophilic secretions by short-stalked capitates. The phytochemical survey was developed on leaf and flower volatile organic compounds (VOCs) and on the essential oil (EO) from the flowering aerial parts. The VOC profiles represented an element of novelty and were dominated by oxygenated monoterpenes, among which 1,8-cineole and β-pinene were the most abundant (77.40 %, 7.11 % leaves; 81.08 %, 10.46 % flowers). The EO of L. dentata was dominated by oxygenated monoterpenes with a high percentage of 1,8-cineole (69.08 %), followed by β-pinene, trans-pinocarveol and myrtenal. Evaluations about the ecological role, the potential biological activity and the sensory attributes were proposed, based on literature contributions.
