The moldavian dragonhead (Dracocephalum moldavica L., Lamiaceae) is an annual plant native in Central Asia and naturalized in Eastern and Central Europe where it is used in folk medicine as antiseptic and stimulating remedy. We carried out qualitative and quantitative phytochemical investigations on moldavian dragonhead herb and on its extracts (tincture and infusion). Plant samples were gathered in different stages of the ontogenesis from cultures in Hungary and Romania (Transylvania). In herb gathered during the reproductive stage of the ontogenesis we measured 0.83% (v/m) of essential oil, in which we identified by GC analysis five main components: geranyl acetate: 33.1%; geranial: 28.2%; neral: 19.8 %; geraniol: 8.2% and neryl acetate: 2.4%. In the essential oil distilled from tincture the geranyl acetate (58.2%) was the main component while in the volatile oil distilled from infusion, the major compound was geraniol (60.1%). A methanolic extract of the herb was investigated by HPLC. Following on-line analysis of spectra, five components were classified as flavonoids; rosmarinic acid was identified by addition of authentic standard. The amount of two phenol carboxylic acids (caffeic and rosmarinic acid) was measured by TLC-densitometry. High values of phenolic compounds were measured in samples gathered during the vegetative stage of the ontogenesis, such as: rosmarinic acid: 2.84 g%; caffeic acid: 50.3 mg%; total flavonoids: 0,58 g%; tannins: 12.9 g%.

Cherries are known as health friendly fruits due to their abundant phytochemical compositions. This study was conducted to determine phytochemical and pomological fruit properties of different cherry species including mahaleb (Prunus mahaleb L.), wild sweet cherry (Prunus avium L.), wild sour cherry (Prunus cerasus L.), two sweet cherries (‘Napoleon’ and ‘Starks Gold’) and one sour cherry (‘Kütahya’) cultivars. For this aim, together with various pomological traits, total phenolics and anthocyanin contents, antioxidant capacity, organic acids, sugars, were analyzed in fruits of relevant genotypes. Results of all examined traits significantly varied between genotypes. Mahaleb showed the highest TSS (30.17%), fructose (8.71 μg/g) and glucose (20.74 μg/g) contents. Wild sour cherry gave the highest antioxidant capacity (13.25 mmol TE/ kg total weight), anthocyanin (351.0 mg Pg-3-glk/kg total weight), citric acid (0.56 μg/g) and malic acid (2.96 μg/g) contents. As a rootstock, mahaleb was found to be superior in some of the traits when compared to wild sweet cherry. Significant correlations were observed between various traits. Additionally, principal component analysis (PCA) revealed different relationships among the traits and evaluated genotypes.
