Quote:There is a little bit of interesting history connected with the melting point of harmaline. A report appeared that described an alkaloid from Peganum harmala that looked like harmaline but which melted 18 °C too high, and so it was thought to be an isomer and was given the name harmadine. This was all cleared up a few years later when it was observed that on an open melting point block, harmaline had a mp 242-244 °C (with beginnings of sublimation at 189 °C) and harmadine had the values of 241-243 °C and 178 °C. In a capillary tube, harmaline melted at 256°C and harmadine at 257 °C. So, harmadine is now a synonym for harmaline.
Some melting point information for harmaline from TiHKAL. The relatively low heat of boiling water shouldn't damage the alkaloids, keep in mind that ayahuasca is often boiled for hours on end and is still active. You could always use a fan as well.
Personally I wouldn't rush the process though, if DMT/caapi have taught me one thing it is that patience is a virtue.
