Effect of fertilization on the development and yields of pot marigold (Calendula officinalis L.)

Published Online: 04 Apr 2014
Page range: 5 - 12

Abstract

Summary

In 2007-2009, a pot experiment was carried out in a greenhouse at the University of Warmia and Mazury in Olsztyn on cv. Promyk pot marigold (Calendula officinalis L.). The aim of the study was to assess the impact of nitrogen and magnesium in plant growth and development and yield of marigold. The experiment included two factors: nitrogen fertilization (g.pot-1): A-0 (control), B-0.3, C-0.6 (0.6+0), D-0.9 (0.6+0.3), E-1.2 (0.6+0.6) and magnesium fertilization (g.pot-1): a-0 (control), b-0.5. The experimental part of the research was designed according to the independent series method and set up in 4 replicates, 4 pots in one replicate, in modified Kick-Brauckmann pots. The experiment demonstrated a significant effect of nitrogen fertilization on the plants hight, number of pot marigold inflorescences, fresh inflorescences weight, fresh and airdry ligulate weight. Magnesium fertilization had a positive effect on all the analyzed traits. No statistical correlation was proven between the nitrogen and magnesium fertilization

Determination of lotaustralin in Rhodiola species

Published Online: 04 Apr 2014
Page range: 13 - 23

Abstract

Summary

In our research, the concentration of lotaustralin in the roots of two species Rhodiola kirilowii and Rhodiola rosea were compared. Aqueous and hydroalcoholic extracts from those plants were analyzed too. To determine the content of this compound the ultra performance liquid chromatography - tandem mass spectrometry (UPLC-MS/MS, Waters) was used. The obtained results showed that the content of measured lotaustralin depends on the species of Rhodiola. R. rosea roots are the richer source of lotaustralin then R. kirilowii. The same situation was observed in the extracts. A hydroalcoholic extract from R. rosea contains up to 135.276 mg of lotaustralin in 100 g of dry powdered material. In the case of R. kirilowii extracts, an aqueous extract contained more lotaustralin (74.791 mg/100 g of dry powdered material) then a hydroalcoholic extract.

Antimicrobial and antioxidant activity of Epimedium pinnatum

Published Online: 04 Apr 2014
Page range: 24 - 34

Abstract

Summary

Epimedium pinnatum (Berberidaceae family) is used as an aphrodisiac in traditional Chinese medicine (TCM). The aim of this study was to evaluate the antimicrobial and antioxidant activity of E. pinnatum extracts (ethanol, methanol and aqueous extracts). Total phenolic (TPC) and flavonoid contents (TFC) of each extract were assessed by spectrophotometric methods. It was exhibited that methanol extract had better antimicrobial activity than those of ethanolic extract or aqueous extract. The TPC and TFC of E. pinnatum extracts was higher in methanol extract (149 and 36.6 mg/g) than that of ethanolic extract (137.2 and 19.5 mg/g) and aqueous extract (86.2 and 8.4 mg/g). The methanol extract had lower IC50 value (200 µg/ml) than ethanolic (250 µg/ml) and aqueous extract (400 µg/ml). There was a positive correlation between TPC, TFC in E. pinnatum extract and their antioxidant and antimicrobial activity

Preliminary study on the impact of methanolic extract of Elephantopus scaber Linn. on hair growth promoting effect in rats

Published Online: 04 Apr 2014
Page range: 35 - 45

Abstract

Summary

Methanolic extract of Elephantopus scaber leaves was investigated for its role in hair growth in experimental rats. The 2% and 5% solution of prepared formulation using methanolic extract was studied for hair growth on wistar rats for 30 days. Minoxidil (2% solution) was taken as a reference standard. The prepared hair oil formulation of methanolic extract significantly (p<0.01) potentiated the hair growth initiation and completion time with dosedependent improvement in skin biopsy, hair length and hair weight. In vitro hair follicles development study showed the significant (p<0.05) improvement in the initiation of new hair follicles. Above mentioned results indicated that the methanolic extract of E. scaber rendered significant hair growth promotive effect

Interrelationships among selected essential elements in medicinal plant raw materials and their water-extractable forms

Published Online: 04 Apr 2014
Page range: 46 - 58

Abstract

Summary

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.
