Hi all, hot topic again..
with regards to the gcms of the 1985, i thought i would come make a posting again.. albeit a more intellectual one just incase more people get caught up in the spiral and fall into different "camps" with different motives/motivations.
chemical analysis of agarwood has been on going since the 1970s... and it is still on going i.e. every year or so you may find new scientific literature on new compounds found in agarwood etc..
i have attached below my analysis of the GCMS report, with each of the compounds present and its cross-references that validates them to be agarwood constituents.. some of these literature new.. some old. even rozi mohd has also written in his book that gcms of agw remains not fully optimized.. perhaps give the technology and demand a bit more time as most GCMS is still used for stronger volatiles.. and the result of a GCMS is strongly affected by the column used, the temperature, and the solvent used, for example dichloromethane vs acetone gives two different populations and GCMS profiles.
nevertheless, on the question of aristolene, valerianol, etc, these are quite major agarwood constituents ins ome species, i.e. crassna, malaccensis etc.
if the aim was to "dilute or cut" an agarwood extract as this is, you will not see high percentages of Eudesmol, Aristolene, Valerianol, Guaic acetate etc. you might see these markers fall down to very low percentages as the cutting agent is increased. but so far, there is no major cutting agent present, and no cistus/labdanum compounds present... if any of these labdanum, benzoin, etc resins are present, it would have been obvious in the GC.
pthlates etc are commonly known to use to cut oils, but in logical sense.. whom would want to cut an oil by adding 0.7% only to it?! it would be 7%.... 70% even... but not everyone may have the same logical view. btw i found a 1.2% in a famous oil from someone, and to me that was a hotter potato, and i still view that result as a dipstick contamination. a couple of people aware of this also deemed it to be vessel leaching, but when "someone" heard about this.. and contacted me, tried to ask me to generate posts/publicity to "attack" someone's brand/reputation etc, i immediately found this whole matter extremely distasteful. in my current olfactory journey to bring great scents to the world.. never was i interested in the political games people play with each other.. and i would also never want to be used as a "weapon" or a "pawn" in the agendas/games people have.
i personally flag out five of the components in red as they are not found in scientific literature to be known to be present in agarwood. in my opinion, either undiscovered yet or most probably a cross contamination from the facility especially without much standards/regulation in those days. it was known to be a chinese medicine/herb extraction facility.
the KZ1985 can be easily verified to be old. the medicinal hall owned by mr Lee Teng Kian, known as Chop Tye Ah (govt reg 00605700D 2nd generation partnership) has been operating in Singapore since 1934. Mr Lee's brother is still around, so are all his children. His two staff, one by name of Lan Hua, and the other called Yue Er both had worked for him for 45 and 42 years respectively. if you are resourceful enough in Singapore you might have been to this medicinal hall. i'm still in good contact with Yue Er, and although she's 70, if anyone in singapore or malaysia wants to hire her to work in a medicinal hall etc please let me know.. it sucks to be unemployed after working your life away with minimal retirement benefits...
Why did i not make a formal post on my site on this? i thought it could be good to give it a rest. at the same time, there is actually a whole FULL bottle of this in Mr Lee's estate, but contents unverified, i received photographs of it from his son. and another former business partner of mine has some 1985, probably tens of millilitres with his own crazed dream of making it rich from this oil. it makes no sense to me.. if you take on the journey of scent and artistry.. why must people turn it into investments.. and taint it with the scent of money??
