The aim of the study was to estimate the influence of soil pH on the uptake of copper, zinc, and manganese by Valeriana officinalis. Preliminary studies involved soil analyses to determine acidity, organic matter content, and copper, zinc, and manganese total and bioavailable forms. The study involved atomic absorption spectrometry to determine the concentration of the elements, and mineral soi...

The effects of extracting solvents (dichloromethane, ethyl acetate and methanol) on the valerenic acid content and antioxidant activity of roots extracts of Valeriana jatamansi (cultivated and wild) were investigated. The tested plant extracts contained appreciable amounts of valerenic acid content which affects the antioxidant potential of plant extracts. Higher concentration of valerenic acid...

Epilepsy is a neurological disorder characterized by unprovoked, recurring seizures that disrupts the nervous system and can cause mental and physical dysfunction. Based on the ethno pharmacological information of the plant, the methanolic and aqueous extracts of the flowers of Nepeta bractaeta was evaluated for its antiepileptic activity. The methanolic and aqueous extracts of the flowers of N...

Several clinical studies have shown that valerian is effective in the treatment of insomnia, most often by reducing sleep latency. A double-blind, placebo-controlled trial compared a 400-mg aqueous extract of valerian and a commercial valerian/hops preparation with placebo of encapsulated brown sugar. A total of 128 volunteers completed a subjective study evaluating the effects of single doses ...

Ever since the discovery of the element iodine by Courtois (1) in 1812 and the first clinical uses of this substance in the treatment of goiter by Prout (2) in 1816 and by Coindet (3) in 1820, almost continuous researches on the relationship of iodine to thyroid function have been in progress. The greatest obstacle in the way of these investigations has been the lack of a reliable method for th...

Observation on morpho-agronomic characteristics of valerian propagated in vitro needed determine their morphological production field. The study aimed observe derived from culture. experiment was conducted at Indonesian Spices...

Eleven indole alkaloids, comprising four corynanthean, two eburnane, one aspidofractinine, one secoleuconoxine, one andranginine, and two pauciflorine type alkaloids were isolated from the stem-bark and leaf extracts of Kopsia pauciflora. Their structures were determined using NMR and MS analyses. The catharinensine type alkaloid kopsirensine B and the secoleuconoxine alkaloid arboloscine A sho...
