To test whether the internal transcribed spacer 2 (ITS2) region is an effective marker for using in authenticating of the Schisandra chinensis at the species and population levels, separately. And the results showed that the wild populations had higher percentage of individuals that had substitution of C→A at site 86-bp than the cultivated populations. At sites 10-bp, 37-bp, 42-bp and 235-bp, these bases of the Schisandra sphenanthera samples differed from that of S. chinensis. Two species showed higher levels of inter-specific divergence than intra-specific divergence within ITS2 sequences. However, 24 populations did not demonstrate much difference as inter-specific and intra-specific divergences were concerned. Both S. chinensis and S. sphenanthera showed monophyly at species level, yet the samples of different populations shown polyphyly at population level. ITS2 performed well when using BLAST1 method. ITS2 obtained 100% identification success rates at the species level for S. chinensis, with no ambiguous identification at the genus level for ITS2 alone. The ITS2 region could be used to identify S. chinensis and S. sphenanthera in the “Chinese Pharmacopoeia”. And it could also correctly distinguish 100% of species and 100% of genera from the 193 sequences of S. chinensis. Hence, the ITS2 is a powerful and efficient tool for species identification of S. chinensis.

The focus of this study is based on the egzamination of the germination traits and the development of thermal models of the medicinal plant Salvia leriifolia Benth. A laboratory experiment was carried out at constant temperatures ranging from 0 to 35°C, at 5°C intervals in a completely randomized design with eight replications. To describe the germination rate response to temperature, three regression models, namely Intersected-Lines (ISL), Quadratic Polynomial (QPN) and Five-Parameters Beta (FPB) were used. The highest Germination Percentage (GP) (92.8%) occurred in 15°C, but GP in the range of 10–25°C was not significant (p≤0.05). The germination process stopped at 0°C and at above 30°C. The results indicated that the highest Germination Rate (GR), the lowest Mean Germination Time (MGT) and also times to 50% germination (D50) were obtained at 20°C. Seeds did not reach to their 50% germination level in temperatures higher than 25°C. The FPB model had the best realistic estimation for cardinal temperatures. Based on models estimation, Base (Tb), Optimum (To) and Ceiling (Tc) temperatures were in the ranges of (1–1.9°C), (18.1–20.8°C) and (34.5–38.7°C), respectively.

In the study, the relationships were investigated among N, P, Fe, Zn, Mn and Cu, in medicinal plant raw materials (herbal bags) and their water-soluble chemical forms in infuses. 42 independent samples of plant materials were chosen, represented by different morphological plant parts as herbs, leaves, flowers and fruits. The elements were determined by UV/Vis spectrometry (non-metals), and FAAS (metallic elements) after previous mineralization of plant samples (total concentrations), and directly in herbal teas (water-extractable forms). Most frequently the correlations between non-metals and Zn and Mn occurred, both between their total contents the water-extractable forms. Statistically significant correlations were also found in pairs: Zn-Mn, Fe-Zn, Mn-Fe, and Cu-Zn. Application of multivariate analysis revealed that cluster analysis grouped the studied samples into clusters with similar levels of the analyzed elements, and principal component analysis allowed the identification of water-extractable Zn, P-PO4 and water-extractable Cu as the most crucial factors determining the differentiation of the studied plant samples.

The peculiarities of heavy metals accumulation by wild medicinal and fruit plants. The article shows the results of studies of heavy metals accumulation by wild medicinal and fruit plants. Special attention is given to the investigation of roadside phytocenoses. Reliable differences in chemical composition of plants from background and transformed habitats are revealed. The influence of morphological and phenological characteristics of the species on the peculiarities of heavy metals accumulation is also determined.

Eupatorium triplinerve Vahl belongs to the Asteraceae family, popularly known as Ayapana. It is a perennial shrub native to Amazon rainforests of South America. Its leaves are used through infusions, decoctions, baths, and tea. It is largely used in Brazilian folk medicine as sedative, febrifuge, stimulant, tonic and anti-inflammatory. The essential oil from aerial parts of Eupatorium triplinerve was analysis by gas chromatography mass spectroscopy (GC-MS). Thirty compounds representing 98.24 % of the oil were identified. The major compounds were 2-tert-butyl-1,4-methoxybenzene (74.3 %) and b-Selinene (8.6 %). The antibacterial activity of the essential oil was evaluated against ten bacteria (including Gram positive and Gram negative) and six phytopathogenic fungi. The oil exhibited moderated antibacterial and strong antifungal activity against all the test pathogens. The highest zone inhibition was recorded against Salamella typhae (21 mm) followed by Shigella sonnei (18 mm) at a concentration of 20μl/ disc on the other standard Ampicillin 20mg/ disc showed on average of 14-34 mm diameter of zone inhibition against the test organism. The lowest antifungal activities were recorded against Macrophomina phaseoline, and Botryodiplodia theobromae. The highest Alternaria alternate (12000 ppm). Further pharmacological and toxicology studies will be required to establish the therapeutic uses of this oil.

The aim of the research was finding the best conditions for germination of Chamaenerion angustifolium seeds in a laboratory (light, temperature ranging from 200C to 300C). For two months after the harvest the germination capacity ranged from 40% to 80%. In next months the capacity decreased. In March and April it increased again, reaching as much as 80%. Seven years after the harvest diaspores lose their germination capacity.

Paeonia ostii is known for its excellent medicinal values as Chinese traditional plant. To date, the diversity of culturable endophytes associated with P. ostii is in its initial phase of exploration. In this study, 56 endophytic bacteria and 51 endophytic fungi were isolated from P. ostii roots in China. Subsequent characterization of 56 bacterial strains by 16S rDNA gene sequence analysis revealed that nine families and 13 different genera were represented. All the fungal strains were classed into six families and 12 genera based on ITS gene sequence. The biosynthetic potential of all the endophytes was further investigated by the detection of putative polyketide synthase (PKS) and nonribosomal peptide synthetase (NRPS) genes. The PCR screens were successful in targeting thirteen bacterial PKS, five bacterial NRPS, ten fungal PKS and nine fungal NRPS gene fragments. Bioinformatic analysis of these detected endophyte gene fragments facilitated inference of the potential bioactivity of endophyte bioactive products, suggesting that the isolated endophytes are capable of producing a plethora of secondary metabolites. These results suggest that endophytes isolated from P. ostii had abundant population diversity and biosynthetic potential, which further proved that endophytes are valuable reservoirs of novel bioactive compounds.

As a part of our ongoing collaborative effort to discover the anticancer activity of the phenolics isolated from terrestrial plant sources, the EtOH extract of the aerial parts of the Egyptian medicinal plant Diplotaxis harra (Forsk.) Boiss. was in vitro investigated for its cytotoxicity against HCT116, HepG2 and MCF-7 cell lines, and resulted with IC50=4.65, 12.60 and 17.90 μg/ml, respectively. Doxorubicin (+ve control) showed in vitro cytotoxic activity with IC50=3.64, 4.57 and 2.97 μg/ml, respectively. The phenolic-rich fraction of the EtOH extract was subjected to further fractionation, which led to the isolation of five flavonoids identified as quercetin, quercetin 3-O-β-glucoside, isorhamnetin 7-O-β-glucoside, apigenin 3-O-β-rhamnoside and kaempferol 3-O-β-glucoside, according to its’ spectral data and comparison with the literature. Furthermore, the isolated flavonoids showed in vitro cytotoxicity against HCT116 cell line with IC50=20.1, 24.3, 22.8, 23.4 and 41.9 μg/ml as determined by MTT method.
