	abstract = {Samples of Hesperozygis ringens (Benth.) Epling and Hesperozygis rhododon Epling essential oils were analyzed by a combination of analytical techniques: capillary gas chromatography, liquid/solid chromatography, GC/MS coupling, and NMR spectroscopy. Twenty-four components have been identified representing altogether more than 95\% of the oil content. The oil of H. ringens is constituted mainly by pulegone (79.2\%) accompanied by several oxygenated derivatives (pulegone oxides, 1.2\%; 8-hydroxy-p-menth-3-one, 1.3\%; and 8-hydroxy-p-menth-4-en-3-one, 3.7\%); that of H. rhododon contains menthone and pulegone as main compounds in almost comparable amounts (43.4\% and 29.6\%, respectively). Tests carried out on lettuce seeds using alcoholic extracts of the two species showed significant antigerminating properties mainly for H. ringens. The same activity was observed with its essential oil.},

	abstract = {The antioxidant capacities (oxygen radical absorbance capacity, ORAC) and total phenolic contents in extracts of 27 culinary herbs and 12 medicinal herbs were determined. The ORAC values and total phenolic contents for the medicinal herbs ranged from 1.88 to 22.30 mu mol of Trolox equivalents (TE)/g of fresh weight and 0.23 to 2.85 mg of gallic acid equivalents (GAE)/g of fresh weight, respectively. Origanum x majoricum, O. vulgare ssp. hirtum, and Poliomintha longiflora have higher ORAC and phenolic contents as compared to other culinary herbs. The ORAC values and total phenolic content for the culinary herbs ranged from 2.35 to 92.18 mu mol of TE/g of fresh weight and 0.26 to 17.51 mg of GAE/g of fresh weight, respectively. These also were much higher than values found in the medicinal herbs. The medicinal herbs with the highest ORAC values were Catharanthus roseus, Thymus vulgaris, Hypericum perforatum, and Artemisia annua. A linear relationship existed between ORAC values and total phenolic contents of the medicinal herbs (R = 0.919) and culinary herbs (R = 0.986). High-performance liquid chromatography (HPLC) coupled with diode-array detection was used to identify and quantify the phenolic compounds in selected herbs. Among the identified phenolic compounds, rosmarinic acid was the predominant phenolic compound in Salvia officinalis, Thymus vulgaris, Origanum x majoricum, and P. longiflora, whereas quercetin-3-O-rhamnosyl-(1 {\textendash}> 2)-rhamnosyl-(1 {\textendash}> 6)-glucoside and kaempferol-3-O-rhamnosyl-(1 {\textendash}> 2)-rhamnosyl-(1 {\textendash}> 6)-glucoside were predominant phenolic compounds in Ginkgo biloba leaves.},

The three latter products display unusual stereochemistry of the 3,4-hydroxyphenyllactic acid unit(s), which to the authors{\textquoteright} best knowledge has never been reported before in similar compounds. Moreover, lithospermic acid B (and its stereoisomers), p-menth-3-ene-1,2-diol 1-O-beta-glucopyranoside, 12-hydroxyjasmonic acid, and 12-hydroxyjasmonic acid 12-O-beta-glucopyranoside were isolated for the first time from Origanum species.},
