AbstractThe content of ursolic acid and oleanolic acid was determined in different plant parts of two Glechoma species, G. hederacea and G. hirsuta. To achieve optimal extraction conditions of ursolic acid and oleanolic acid from plant material, several methods including maceration, heat reflux, Soxhlet, and ultrasonic extraction, as well as various solvents (methanol, dichloromethane, ethyl acetate), were investigated and compared.For the simultaneous quantification of pentacyclic triterpenes in extracts from Glechoma sp., an UPLC-MS/MS was developed and validated. The method exhibited good linearity, precision, and recovery, and it also was simple, specific, and fast. We developed the method for future application in the quality control of plant materials and botanical extracts containing ursolic acid and oleanolic acid. With regard to the triterpene constituents, both G. hederacea and G. hirsuta can be used equally, and the aboveground parts of both species, but the leaves especially, are abundant sources of ursolic acid (7.1 – 7.5 mg/g dry weight [DW]). Dichloromethane as an extractant provided the best extraction efficiency as well as selectivity to obtain Glechoma extracts rich in triterpenes as compared to methanol and ethyl acetate, regardless of the particular extraction technique. Dry dichloromethane extracts from aerial parts of Glechoma sp. obtained by the heat reflux method resulted in products with a high content of UA (17 – 25% w/w) are considered to be convenient and rich sources of this compound.

The present study was conducted to determine the variation in the content of hyperforin, hypericin and pseudohypericin in Hypericum triquetrifolium Turra growing wild in four locations of Turkey. The aerial parts, representing a total of 30 individuals, were collected at full flowering and dissected into floral, leaf and stem tissues. After drying at room temperature, the plant materials were assayed for their chemical contents by HPLC. The populations varied significantly in chemical contents. Hyperforin content ranged from 0.05 to 0.56 mg/g, hypericin from 0.74–1.98 mg/g, and pseudohypericin from 0.72–2.26 mg/g, dry weight. Among the different plant parts, the flowers were found to be the principle organ for hyperforin accumulation, while hypericin and pseudohypericin were accumulated mainly in leaves. Such kinds of data could be useful for optimizing the processing methodology of wild-harvested plant material and phytochemical evaluation of H. triquetrifolium.

A new oleanolic acid triterpene glucoside, 3- O-β-D-glucopyranosyl-3β,21β,28-trihydroxy-olean-12-en-27-oic acid (1), has been isolated together with twelve known compounds from the chloroform and ethyl acetate extracts of Genista numidica Spach (Fabaceae) aerial parts. The structures were elucidated by spectroscopic and spectrometric analyses, mainly 1D-, 2D-NMR and MS data, and comparison with the literature. The antiproliferative activity of isolates was investigated on Jurkat, HeLa, and MCF7 cell lines. The most active triterpene, 3- O-β-D-glucopyranosyl-olean-12-en-3β,27,28,29-tetraol, showed activity in all cell lines. Further studies revealed that this compound induced in HeLa cells a cytostatic response.

AbstractTargeted isolation based on a combination of NMR and HPLC-PDA-MS of a dichloromethane extract of Thymus vulgaris Varico 3 aerial parts afforded one new p-cymene dimer, 6,3′,4′-trihydroxy-5,5′-diisopropyl-2,2′-dimethylbiphenyl (1), together with two known p-cymene derivatives (2 and 3), as well as five known compounds, namely, thymol (4), oleanolic acid (5), ursolic acid (6), cirsimaritin (7), and xanthomicrol (8). The structural elucidation of all compounds was performed by spectroscopic analyses, including 1D and 2D NMR, and HRESIMS experiments. The biphenyls were assayed for their inhibitory activity on tyrosinase. Compounds 2 and 3 showed negligible activity on tyrosinase, while compound 1 effectively inhibited the enzyme with 35% (± 0.3) inhibitory activity, higher than the inhibition of the reference compound kojic acid (18.6 ± 0.02).

Camptotheca acuminata plantations were established in southern Louisiana in an effort to provide raw plant materials for deriving camptothecins, compounds having antitumor activity. This study was conducted to evaluate the growth and camptothecin distribution within the trees. It was found that all plant parts contained camptothecins following 1 year of growth in the field. Branches, roots, and stems accumulated significantly higher concentrations of camptothecins than leaves. Bark was significantly higher in camptothecin concentration than wood. Younger and older tissues within a growing season were not significantly different in camptothecin concentrations. High correlation in camptothecin concentration was found between branch and stem, root and stem, and root and branch, whereas little correlation was observed between bark and wood, and leaf and any other plant component. Field-grown C. acuminata has the observed characteristic of multiple current-year branching. The proportion of bark in term of dry weight and dimension decreased as trees increased in diameter. Dried shoots (bulk) contained 0.042% camptothecin, and dried roots (bulk) contained 0.051% camptothecin. Keywords: Camptotheca acuminata, medicinal plants cultivation, camptothecin content, camptothecin distribution, biomass.

In the present study, the presence of the phloroglucinol derivative hyperforin, the naphthodianthrones hypericin and pseudohypericin, the phenylpropane chlorogenic acid and the flavonoids rutin, hyperoside, kaempferol, isoquercetine, quercitrine, and quercetine was investigated inHypericum leptophyllumHochst., an endemic Turkish species for the first time. The aerial parts representing a total of 30 individuals were collected at full flowering and dissected into floral, leaf, and stem tissues. After being dried at room temperature, the plant materials were assayed for secondary metabolite concentrations by HPLC. Aerial plant parts accumulated chlorogenic acid, hyperoside, isoquercetine, quercitrine, and quercetine, but they did not accumulate hyperforin, hypericin, pseudohypericin, rutin, and kaempferol. Accumulation levels of the detected compounds varied with plant tissues. Such kind of data could be useful for elucidation of the chemotaxonomical significance of the corresponding compounds and phytochemical evaluation of this endemic species.

Abstract The aerial parts of T. gallica collected from three different locations (arid, humid and semi-arid) were extracted using ethyl acetate. The crude extracts were subjected to phenolic appraisal and antiproliferative activity using ELISA and xCELLigence assays. The total phenolic and flavonoids were evaluated using appropriate techniques to give a yield of total phenolics ranging between 238.46 and 348.56 mg GAE (Gallic acid equivalent)/g dry weight extract. The flavonoids yield was found to vary from 36.6 to 103.14 mg QE (quercetin equivalent)/g dry weight extract. Moreover, the extracts were tested against rat brain tumor (C6) and human cervix carcinoma (HeLa) cell lines and displayed important differences in activity. These disparities highlighted the effect of climatic factors as quality determinants of secondary metabolites and therefore as a key control of the biological therapeutic effect.

Abstract The triterpenes friedelin (1), β-friedelinol (2) and 3,15-dioxo-21α-hydroxyfriedelane (3) in the aerial parts of Maytenus robusta, a Brazilian medicinal plant with antiulcer potential, were seasonally quantified by gas chromatography flame-ionization detection (GC-FID) using an external standard. The method was found to be linear, precise and sensitive. Compounds 1 and 2 were found in M. robusta leaves and branches, with highest concentrations in the leaves collected in autumn, i.e. 3.21 ± 0.16 and 12.60 ± 1.49 mg g−1 dry weight of 1 and 2, respectively. On the other hand, compound 3 was found only in the branches, with the highest concentrations in winter and autumn (0.21 ± 0.01 and 0.20 ± 0.02 mg g−1). The results allow to define the optimal season and plant parts for the collection of M. robusta as a phytotherapeutic drug.

A quick and accurate HPLC method has been developed for the simultaneous quantification of two bioactive triterpenes, ursolic acid and oleanolic acid in Paulownia leaves. The samples were analyzed on a Shim-pack ODS-CLC (M) (4.6 mm × 250 mm, 5 μm) column kept at 21 °C, using the methanol and aqueous phase containing 0.05%phosphoric acid with the volumetric ratio of 91.7:8.3 as the mobile phase at a flow rate of 0.6 mL/ min, and the detection wavelength was set at 210 nm. The method was validated and applied to the simultaneous quantification of the two triterpenes in Paulownia leaf extract. The standard curves were established in the range of 0.44 ~ 8.75 μg for oleanolic acid and 0.92 ~ 18.37 μg for ursolic acid. The contents of oleanolic acid and ursolic acid in leaves of Paulownia were determinated using the HPLC method and the contents were 3.87 mg/g and 13.61 mg/g, respectively.
