The solubility of mitragynine was found to increase from 18.7 ± 0.4 μg/mL in buffer at pH 9, to 64.6 ± 1.2 μg/mL in water and 88.9 ± 1.6 μg/mL in buffer pH 7, while being the highest at pH 4 …

Mitragynine is insoluble in water but soluble in conventional organic solvents, including acetone, acetic acid, alcohols, chloroform and diethyl ether providing fluorescent solutions. Mitragynine …

Mitragynine are the main indole alkaloids that are most commonly found in the leaves of M. speciosa(Ya et al., 2019). Parthasarathy et al., 2013) reported that more mitragynine …

half-life for mitragynine ranged from 0.8-18h (80ºC) and 9.5h at 60ºC. Results showed that MG was more acid-labile than alkaline labile. MG was stable at pH 4 and 6, even when exposed to …

measure the solubility limit of Mitragynine at pH of 4 and 7, which gives 130 and 83 µm [54] (Table 1). The predominate compound is an indole alkaloid, that possesses corynanthe type …

Mitragynine exhibited weak solubility in basic media and water and conversely in acidic conditions; however, it is acid-labile [108]. The solubility has been documented to be 18.7 …

2015年3月18日 · Mitragynine is a lipophilic alkaloid, as indicated by a logP value of 1.73. Mitragynine had poor solubility in water and basic media, and conversely in acidic …
