Thanks Torsten. Just curious about some nootropics. I think piracetam, hydergine and DMAE are OK. Also lucidril and nicergoline. Is there an amount below which tryptophan is OK? Any recommnded places to order? -b

Anyone know of a website which will tell if a supplement is available without prescription? l-tryptophan and melatonin I belive require prescriptions for import and there are others I would like to check. -b

Got a bit of rot on a graft some time ago. Soln: cut the rot off, stuff the hole with sulfur and stop watering for a while. That was over 6 months ago now and apart from looking a little lop sided its happy and healthy

anyone tried (or have inf. on)tribulus fruit ingested? particularly its use as ayahuasca analogue. 30-40 grams seems like a lot rev. Extracted in hot water I assume. I noticed slight interactions with other herbs even at doses of 5g of whole fruit ground and swallowed. -b

toothache plant (spilanthes spp.) chewing on a bud will numb it up good. easier to find is clove oil which numbs OK but is not nearly as much fun.

Unlikely you can vaporise from raw material. Check out 'Traditional DMT use in australia?' @ shamans chill space though for some thoughts.

Not sure of the available detectors. Perhaps some are coupled with IR which would be the tool of my dreams, but no doubt the price tag of my nightmares. I think databases based on retention time would be unreliable so they may not exist.

The area of peaks are proportional to concentration but not to each other as each component of the extract reacts differently to the detector.

For a given column and solvent system there should be a fixed retention time (time it takes to hit the detector) for various chemicals which have no doubt been analysed before, however the columns performance may change with time so a standard is usually run or used to 'spike' the extract by adding a small amount of standard to it (extract and extract-standard run separately). Not sure about databases. I suspect that the analysis on the GC/MS is a result of the MS. This would make analysis independent of the gasses run through the column and the column performance. Area of the peak is proportional to concentration. A standard of known concentration is usually run to find out a ratio of area-concentration (hope this is accurate as the only machine I have used was a dinosaur). ooops [This message has been edited by bark (edited 30 July 2002).]

I belive you can get combination detectors for HPLC. Perhaps UV and electrochemical would be appropriate. From memory electrochemical detectors can pick up very small concentrations. Not sure how well it would work for ess. oils but should give excellent results with amines. Big advantage with going for HPLC is that you can keep the components of the extract for further analysis by MS IR NMR etc. Essential for identifying unknown components. GC/MS of course destroys the sample. Disadvantage is that if you are not going to do further analysis you will need standards for identification. There are also less problems with damage to the column as there is a continuous flow of solvent which your sample will be soluble in to varying amounts. Chromatography is a very interesting (and huge) topic. Even such simple techniques such as a glass column packed with a silica stationary phase with some pressure (or suction) can separate complex mixtures with some fine tuning of the solvent and (sometimes a lot of) patience.

The melting point of 5MEO and N,N are very close. Assuming the vapourising temps are also close to the same, they could be separated from 5-OH and gramine but not from each other.

Anyone got any info on the vaporisation temperature of N,N DMT 5MEO DMT Bufoteine Gramine ??

Heard many years ago that you could get them to germinate at other times by giving them a period of coldness (fridge for a few weeks?)before planting (or chucking ). never tried it myself but the seeds are cheap and plentiful so it might be worth a try. anyone tried/heard this? -b
