“…However, because of the poor performance of the original system in separating and detecting TTX analogs, an improved analyzer was later constructed. Using HPLC-FLD, naturally occurring TTX analogs, 4- [32], 4,9-anhydro-6-epiTTX, 4-epi-11-deoxy-TTX, and 4,9-anhydro-11-deoxyTTX isolated from puffer and newt specimens and/or frogs [33]. The separation of TTX and 6-epiTTX is considered as a major achievement for this improved analyzer.…”

“…GC-MS analysis is an indirect method to detect TTX in a crude extract which is difficult to purify in other advanced analysis methods [33]. In this method, TTX and its derivatives are dissolved in 2 ml of 3 M NaOH and heated in a boiling water bath for 30 min.…”

“…In addition to the algae and crabs, we proved occasional occurrence of TTX in the annelid Pseudopotamia occelata and the ivory shell Babylonia japonica, and deduced that they also were a part of the food chain links. 14) To facilitate the survey on TTX, we constructed a fluorescence-detection HPLC analyzer, 17) which enabled us to detect, isolate, and determine structures of seven new analogs of TTX from puffer fish, newts, and a frog (structure not shown).…”
