Showing papers on "Mentha pulegium published in 1970"
TL;DR: The callus of Pimpinella anisum was cultured under different physical conditions as well as on different media, and its development was studied, and the two differentiated cultures turned out to have nearly the same oil-spectrum, in contrast to that of roots and leaves of the entire plant.

TL;DR: Dietary supplementation of thyme and mentha separately or in combination improved the meat quality of broiler chickens under heat stress through decreasing the MDA concentration and increasing the pH and moisture content of the thigh muscle.
Abstract: This study was designed to investigate the effects of Thymus vulgaris (thyme) and Mentha pulegium (mentha) powders on meat colour, nutrient composition and malondialdehyde (MDA) where broiler chickens were under heat stress. Two hundred one-day-old male chicks were used in a completely randomized design with four treatments and five replicates each (10 birds per replication). Treatments were the control diet, 0.5% mentha, 0.5% thyme and 0.5% mixture of the two plants. The results showed no effect of dietary supplements on thigh meat redness and yellowness. Both plant products diminished the thigh lightness significantly compared with the control. No significant differences between treatments were observed for the ash, ether extract and crude protein content of the thigh muscle. Supplementation of thyme and mentha separately or together increased the moisture of the thigh muscle significantly, compared with the control. The combination of the plant products resulted in a higher thigh pH and significantly lower malondialdehyde (MDA) concentration in the thigh muscle compared with the control. In conclusion, dietary supplementation of thyme and mentha separately or in combination improved the meat quality of broiler chickens under heat stress through decreasing the MDA concentration and increasing the pH and moisture content of the thigh muscle

TL;DR: The author treats Pulegium Mill, as a good genus, and uses, besides the well-known differences in calyx and corolla, a new character, namely that the anterior stamens are curved towards the upper lip and, together with the posterior ones, ascend under this lip, whereas in Mentha all stamen are straight and diverge from their base.
Abstract: The author treats Pulegium Mill, as a good genus. For the separation of Pulegium from Mentha, he uses, besides the well-known differences in calyx and corolla, a new character, namely that the anterior stamens are curved towards the upper lip and, together with the posterior ones, ascend under this lip, whereas in Mentha all stamens are straight and diverge from their base. On the ground of this character, already used by BRIQUET (1897, p. 208) as being of primary importance Pulegium is related more to genera as Satureja, Micromeria, Melissa, etc., than to Mentha s.s. The genus Pulegium contains 2 or 3 species, the wide-spread P. vulgare Mill., the Corsican P. parviflorum (Req.) G. Sampaio, and perhaps also the Algerian Mentha gattefossei Maire.

TL;DR: A biochemical study of the essential oils of the cultivated Mentha Pulegium Linn has been conducted and it has been proved that d-pulegone was produced at the early stage abundantly and after the climax stage of vegetation, this compound was reduced to l-menthone and d-isomenthone partly.
Abstract: A biochemical study of the essential oils of the cultivated Mentha Pulegium Linn. introduced in Japan from the Botanical Garden of Caen in France has been conducted. From the yield of oils and the contents of each constituent, it has been proved that d-pulegone was produced at the early stage abundantly and after the climax stage of vegetation, this compound was reduced to l-menthone and d-isomenthone partly. Moreover, in the latter stage a small amount of l-menthol appeared by further reduction. The yield of oil was as high as 1.03% to the blooming inflorescence, but the reducing power is largest in the leaf, therefore l-menthol was only detected in the leaves.
