![]() scutellarioides leaves contained three acylated cyanidin diglycosides, one of them containing just a coumaroyl residue, the other two containing one and two additional malonyl residues, whereby malonylated compounds appeared in higher quantities. In addition to rosmarinic acid (RA), which is typical for members of the family Lamiaceae, luteolin and apigenin glycosides were detected by mass spectrometry. On the other hand, higher infrared radiation from MPL and HPS lamps led to increased leaf temperatures compared to plants grown with LED or CDM light, resulting in faster plant development indicated by greater leaf pair formation. Stem elongation was increased in plants grown with MPL and LED light, which was attributed to the higher amount of far-red light in the emission spectra. For detailed description of the phenolic compounds, qualitative and quantitative analysis of selected phenolic compounds were performed by HPLC. Total phenolic compounds were quantified with colorimetric methods. The aim of this study was to investigate both the influence of the spectral quality and the influence of the leaf temperature from four different lamp systems on morphology and secondary metabolites in P. The lamps differed not only in the spectral properties of the emitted light but also in the emission of infrared radiation. ![]() The following four lamp systems were tested: a new microwave plasma lamp (MPL) emitting artificial sunlight, a commercial high-pressure sodium lamp (HPS), a ceramic metal halide lamp (CDM), and light-emitting diodes (LEDs). It is interesting for further investigate the differences of respon between in vitro and in vivo to determine involved factors.Abstract In this study, the influence of different lamp types on physiology and secondary metabolites of Plectranthus scutellarioides (Solenostemon scutellarioides, Coleus blumei) was examined. Unfortunately, the result of invivo assay showed that the chloroform extract treatment with dose level 25 mg/kg BW could not to reduce the number of tapeworm in chicken. The promising activity displayed by a number of extracts has led to further investigation of the active compound. In general, chloroform extract proved to be a more efficient extractant of biologically active compounds than either hexane, ethanol or water extract. Three of four extracts displayed strong anthelmintic activity with the higest activity belong to chloroform extract with EC50 5 mg/ml followed by n-hexane 9 mg/ml and metanol extract 10,2 mg/ml, while water extract has a weak anthelmintic activity with 106,2 mg/ml. The result of phytochemistry analysis showed that Coleus leaves consisted of flavonoid, steroid, tannin and saponin. Anthelmintic activity was evaluated with an assay using chicken tapeworm in a serial microplate dilution method by determination of efective concentration 50 (EC50) using probit analysis. Phytochemical analysis was carried out to determine the chemical compound of secondary metabolites. Leave of painted nettle were collected and extracted with hexane, chloroform, ethanol and water. Study on the chemical compound of painted nettle (Coleus blumei Benth) leave extract and its anthelmintic activity against chicken tapeworm were conducted. ![]()
