“…& Reut., a plant commonly used in North Africa and several other countries, in the form of infusions or syrups, to treat coughs; the biological properties of which remain poorly defined. Previous studies with essential oils extracted from Thymus have shown this plant to have antioxidant and antimicrobial properties in vitro (Benchabane et al, 2012;Hazzit et al, 2006). As part of a comprehensive study aiming to define the properties of T. munbyanus in various cell types and organs, the effect of T. munbyanus essential oil on human sperm integrity and functionality in vitro was analysed to determine the potential utility of these oils in the field of reproductive biology, as pro-or anti-spermatic agents.…”

Traditional medicine has been used worldwide for centuries to cure or prevent disease and for male or female contraception. Only a few studies have directly investigated the effects of herbal compounds on spermatozoa. In this study, essential oil from Thymus munbyanus was extracted and its effect on human spermatozoa in vitro was analysed. Gas chromatography and Gas chromatography-mass spectrometry analyses identified 64 components, accounting for 98.9% of the composition of the oil. The principal components were thymol (52.0%), γ-terpinene (11.0%), ρ-cymene (8.5%) and carvacrol (5.2%). Freshly ejaculated spermatozoa was exposed from control individuals to various doses of the essential oil for different time periods, and recorded the vitality, the mean motility, the movement characteristics (computer-aided sperm analysis), the morphology and the ability to undergo protein hyperphosphorylation and acrosomal reaction, which constitute two markers of sperm capacitation and fertilizing ability. In vitro, both the essential oil extracted from T. munbyanus and thymol, the principal compound present in this oil, impaired human sperm motility and its capacity to undergo hyperphosphorylation and acrosome reaction. These compounds may, therefore, be of interest in the field of reproductive biology, as potential anti-spermatic agents.

“…The major components were carvacrol (44.52%), p-cymene (16.64%) and -terpinene (10.85%), along with other components to relatively low levels of borneol (4.01%) and the sesquiterpene caryophyllene (6.39%). In concordance with this study, the Thymus munbyanus essential oil from Algeria analyzed by Benchabane (2012) was characterized by a large amount of carvacrol (35.2%) followed by thymol (18.5%), terpineol (7.6%), p-cymene (5.1%) and -terpinene (7%) [50] [38].…”

Thymus pallescens de Noé essential oils were isolated from the plant's dried leaves, by hydrodistillation, with different distillation times (30 min, 1, 2 and 3 h). The essential oils compositions and their antioxidant, antimicrobial and insecticidal activities were examined. The chemical compositions of the oils were determined by GC and GC-MS. The antioxidant capacity was tested by four complementary methods: thiobarbituric acid reactive substances, ferric reducing power and scavenging of radicals DPPH • (2,2-diphenyl-1-picrylhydrazyl) and ABTS •+ [2,2 -azino-bis (3-ethylbenzthiazoline-6-sulfonic acid)]. The antimicrobial activity was tested against three bacteria, two gram-positive (Staphylococcus aureus and Bacillus subtilis) and one gram-negative (Escherichia coli) and one yeast (Candida albicans). The insecticidal activity against confused flour beetle Tribolium confusum Jacquelin du Val (Coleoptera: Tenebrionidae) was evaluated using direct contact application and fumigant method. The predominant components in the oils were carvacrol (63.3-68.2 %), γ -terpinene (6.9-9.1 %), p-cymene (6.2-10.3 %) and thymol (6.5-7.5 %). The antioxidant activities were dependent on the time of hydrodistillation and the method used. The essential oils extracted for 30 min and 1 h were the most efficient against all the bacteria used.
