Study of Quality Medicinal Plants Bark Walnuts and Extract from it

Abstract

Objective: The bark of walnut is currently poorly understood and is not represented in the Russian State Pharmacopeia. The purpose was to study the quality indicators medicinal plants walnut crust and extracts therefrom were studied: moisture content, total ash, ash insoluble in 10% hydrochloric acid feedstock walnut crust; content of tannins and juglone in walnut crust; GC-mass spectrometric study of the composition petroleum extract from the bark of a walnut. Materials and Methods: Microscopy was prepared by the pharmacopoeial method. The chemical composition of the petroleum extract was investigated by chromatomass spectrometry. Results: The content of glycosides amount in terms of gidroyuglone glucoside and absolutely dry RL was 5.30 ± 0.15. Humidity was 9,41% ± 0,21. total ash content was 10,18% ± 0,1. The ash content insoluble in 10% hydrochloric acid was 4.8 ± 0.16. Gas chromatography-mass spectrometry method in petroleum extraction from the bark of walnut were identified following compounds: oktadetsilgeksanoat (28%) of 4-isopropenyl-1-methyl-2-cyclohexenol-1 (38%), cineole (1,6%), thujone (0.7%), camphor (16.6%), 2benzamidoantrahinone (0.45%), 4,5-dihydroxy-3,4-dihydro-1 (2H)-naftalenon (6.4%) ethyl ester of palmitic acid (8.25%) Toxic effects petroleum extract was TD 50 = 2,5. Chronic absent. All mice in the experimental group had diarrhea. It was established that the extraction has petroleum anthelmintic properties at askaridioze. Conclusions: The analysis of petroleum extraction from walnut partitions was carried out, the content of basic biologically active substances was revealed. The main anatomical and diagnostic signs of walnut bark walls were studied.

Efficacy of Bark (Juglans regia L.) Extracts Against Periodontitis Bacteria: an In Vitro Study

“…The bark of Juglan regia locally known as Deirum in Asia and middleeast countries. This medicinal part can be utilized as a tooth cleaner, cosmetic product for coloring the lips by women and the cosmetic industry 15 . Juglan regia bark is available in different sizes and shapes, fibrous and characterized with resinous, scented features 16 .…”

“…One colony of each isolate was inoculated in a brain heart infusion broth (BHI) and incubated for 3 hours at 37 °C to obtain culture turbidity with standard turbidity (0.5 McFarland standard). On Muller Hinton agar spread 0.1ml of the culture with a sterile swab, dry at room temperature for(10)(11)(12)(13)(14)(15) minutes. Inhibitory activity was detected by the agar well diffusion method, after sterilizing the cork borer, four wells were made on the surface of the culture media with a diameter of 10 mm then add (100 μl) to each well in different concentrations of derum extract.…”
