A colorless needle crystalline, mp 187-188°(decomp.), C_5H_7O_5N_3 was isolated from Quisqualis Fructus (seeds of Quisqualis indica, and Q. indica var. villosa, Combretaceae), a popular ascaricidal crude drug in China and Japan. The compound was considered to be an unknown acidic amino acid and an active principle. So it was named quisqualic acid after the genus name Quisqualis. The chemical structure of quisqualic acid was consedered to be N^2-L-alanyl-3,5-dioxo-1,2,4-oxadiazolidine(Ia) or N^4-L-alanyl-3,5-dioxo-1,2,4-oxadiazolidine (Ib) on the basis of chemical and spectral data. Therefore Ia and Ib were synthesized by routes shown in the chart 2 and 3, respectively. Ib did not agree with quisqualic acid but Ia was identified with the authentic sample. Thus, the structure of quisqualic acid was confirmed to be N^2-L-alanyl-3,5-dioxo-1,2,4-oxadiazolidine satisfactorily. Quisqualic acid is the first instance of natural compound containing 1,2,4-oxadiazolidine ring.

Two new C-methyl flavanones, named matteucin (III) and methoxymatteucin (IV) were isolated from the root of Matteuccia orientalis TREV. (Aspidiaceae), together with the known desmethoxymatteucinol (I) and matteucinol (II). The structures of these flavanones were determined to be (2S)-5,7,2'-trihydroxy-6,8-dimethylflavanone and (2S)-5,7,2'-trihydroxy-5'-methoxy-6,8-dimethylflavanone, respectively, by spectroscopic evidence.

It was reported previously that tricholomic acid and ibotenic acid (new flycidal amino acids isolated from Tricholoma muscarium KAWAMURA and Amanita strobiliformis (Paul) Quel, respectively) have a very good taste.The characteristics of the taste were examined in details, and the followings were observed:1. Taste potency of the new amino acids are much stronger than that of sodium inosinate and sodium glutamate.2. There are synergistic actions between new amino acids and 5′-ribonucleotides.3. DL-erythro-tricholomic acid (synthesized) has an extremely strong delicious taste, but its threo isomer has not.

A colorless pillar crystalline component, m.p. 207° (decomp.), [α]D+80.0°(H2O), C5H8O4N2 of good flavor without smell, and of having insecticidal property was isolated from Tricholoma muscarium KAWAMURA (Jap. name: Haetorishimeji) in the process illustrated in Fig. 1. The compound was considered to be acidic amino acid, still unknown substance, which named tricholomic acid.

From Amanita strobiliformis (PAUL.) QUER. (Jap. name: Ibotengutake), colorless and odorless pillar crystalline component with good flavor, providing remarkable fly-killing properties, m. p. 151-152° (decomp.), C5H8O5N2 was isolated. The compound is considered to be an unknown acidic amino acid and is called ibotenic acid, naming after the ibotengutake.

The terrestrial portion of Euphorbia watanabei MAKINO was found to contain, besides nonacosane (?), tetracosanol, a wax-like, m.p. 59〜60°, and β-sitosterol, five-membered ring triterpenes taraxerol acetate, lupeol acetate, alunusenone (?), taraxerone, luperone, and taraxasterol. It is interesting from botanical aspects that euphane series triterpenes, which would be anticipated from Euphorbia spp., were not obtained.

The NMR spectrum of domoic acid (in CF_3COOH) indicates signals for a methyl at 1.43 p.p.m. (d;J=6.6 c.p.s.) and at 1.94 p.p.m. (a broad singlet), and no signal for an ethyl group. The methyl signal at 1.94 p.p.m. shows a long-range I-I coupling due to spin decoupling. The NMR spectrum of trimethyl domoate (in CDCl_3) shows a doublet methyl (J=7.0 c.p.s.) at 1.29 p.p.m., a methyl signal which indicates an allylic coupling at 1.79 p.p.m., and an olefinic proton signal corresponding to 3H at 5.5〜6.6 p.p.m. From its first-order analysis, the configuration of the 1,3-hexadienyl side chain was determined as trans : trans : S-trans. The infrared spectra of both domoic acid and trimethyl domoate show absorption due to the trans-double bond. The NMR spectrum of tetrahydrodomoic acid (in CF_3COOH) shows signals for a methyl bonded to a secondary carbon at 1.12 p.p.m. (d;J=6.0 c.p.s.) and at 1.22 p.p.m. (d;J=6.6 c.p.s.). It was concluded from these observations that the structure of domoic acid would be more appropriately represented as L_s-arabo-2-carboxy-4-(1-methyl-5-carboxy-trans : trans : S-trans-1,3-hexadienyl)-3-pyrrolidineacetic acid (VIII) rather than the previously proposed L_s-arabo-2-carboxy-4-(1-methyl-2-carboxy-1,3-hexadieny1)-3-pyrrolidineacetic acid (I).
