Comparison of the effects of compost and vermicompost soil amendments in organic production of four herb species
2020
The aim of this study was to compare the effects of using compost and vermicompost as soil amendments in organic herb production, using four herb species (Dracocephalum moldavica L., Melissa offici...
Phenolic compounds of herbal infusions obtained from some species of the Lamiaceae family
2018
Abstract The present investigation was to estimate the total phenolic content and composition of flavonoids and hydroxycinnamic acids in herbal infusions obtained from aerial parts of three Lamiaceae species (Dracocephalum moldavica, Ocimum americanum and Satureja hortensis). The total phenolic content of herbal infusions was determined using a spectrophotometric method, whereas the individual phenolics were assessed by high-performance liquid chromatography (HPLC). The HPLC method was developed and validated. The total phenolic content was measured by applying the Folin-Ciocalteu method with reference to gallic acid. Results were in the range from 29.39 to 65.38 mg estimated as gallic acid…
Substrāta un organiskā mēslojuma ietekme uz Dracocephalum moldavica augu augšanu un fizioloģisko stāvokli
2019
Darba mērķis bija novērtēt dažādu substrātu un mēslošanas līdzekļu ietekmi uz augu augšanu, attīstību un to fizioloģiskajiem parametriem. Pētījumu veica ar Moldāvijas pūķgalvi, novērtējot substrātu, mēslojuma veidu un to koncentrāciju ietekmi uz augu augšanu un fizioloģiskajiem procesiem tajos. Augus audzēja veģetācijas traukos, kur par substrātu izmantoja kūdru vai melnzemi, kam pievienoja dažādus mēslojumus: mikrobioloģisko mēslojumu “Biomikss”, minerālo mēslojumu “Kristalon”, kā arī 20% vermikompostu un 30% vermikompostu. Secināja, ka vermikomposta pievienošana substrātam būtiski uzlabo augu augšanu un attīstību, to vitalitāti, kā arī šiem variantiem uzrādīja augstāko substrāta sāļu konc…
Development of high-performance thin layer chromatography method for identification of phenolic compounds and quantification of rosmarinic acid conte…
2020
ABSTRACT Aim: Representatives of Nepetoideae Burnett subfamily are promising species of the Lamiaceae Martinov family because of accumulating such valuable groups of secondary metabolites as terpenoids and polyphenols. A high-performance thin layer chromatography (HPTLC) fingerprint method for the qualitative determination of phenolic compounds and for the quantification of rosmarinic acid (RA) content in methanol extracts of five species of this subfamily was developed for the first time. Materials and Methods: Dried aerial parts of Dracocephalum moldavica L., Ocimum americanum L., Lophanthus anisatus (Nutt.) Benth., Monarda fistulosa L., and Satureja hortensis L. collected in flowering pe…
