There are many more drugs derived from plants which are successfully established as pharmaceuticals which I have not covered in this section. Scientific research in phytopharmaceutical is on going and is growing rapidly especially
in countries like Malaysia which have an abundance of natural resources. Indiana Kratom Petition in spite of much activity on the chemistry and pharmacology of phytopharmaceuticals thorough investigations on their potential toxicology are lacking. Drew and Myers 1997).
The Ames test is widely accepted worldwide and remains one of the tests for predicting genotoxicity potential. Mouse lymphoma tk gene mutation assay (MLA) is one of the tests specifically to evaluate mutagenesis in mammalian cells. Clive and Spector 1975; Clive et al 1979). Since then the test was gradually optimised until it is widely acceptable for genotoxicity best way to grind kratom bestellen paypal kratom testing. CFSAN 2006; Applegate et al 1990; Sawyer et al 1989 1985; Moore et al 1985).
The crude methanol extract was re-dissolved in 300 ml chloroform and the mixture was transferred into a separating funnel. Four hundred (400 ml) of distilled water was added to the separating funnel and the mixture was shaken thoroughly then left to borneo red vein kratom wirkung stand until two layers were formed. The bottom layer (organic layer) was collected and the upper layer (aqueous layer) was re-extracted with the chloroform again and this step was repeated three times. The collected organic layer was filtered through sodium sulphate anhydrous and the organic filtrate was further dried by rotary evaporator. The crude chloroform extract obtained appeared greasy and very dark green in colour.
The MSE was analysed with UV-VIS spectroscopy to determine the percentage of MIT present. MIT of the different sources was compared via 1D-H-NMR spectra to confirm its purity. D-PBS without magnesium and calcium) were purchased from Invitrogen Corporation (Paisley Scotland UK).
MSE was the main agent used in this study. It has been proposed that MSE kratom onset extracted using modification of Houghton and Ikram method (1986) contains more MIT than any other reported crude buy kratom powder online extraction processes (Baharuldin
2000). MIT was obtained from two sources; IMR Malaysia and from Japan. The young leaves of Mitragyna speciosa Korth were collected from the forest in Behrang Stesen Selangor Malaysia and were processed to obtain the methanolchloroform extract (MSE) at International Islamic University of Malaysia kratom herb speciosa (IIUM). Trace amounts of MIT were obtained from Institute of Medical Research (IMR) Kuala Lumpur Malaysia and used as a reference sample. Larger quantities of MIT were a kind donation from Prof. Hiromitsu Takayama from University of Chiba Japan and were used throughout the study.
