[Development of a Simple Identification Method for Omphalotus guepiniformis by Color Reaction].

A simple method of identification using a color reaction was developed for Omphalotus guepiniformis. Only Omphalotus guepiniformis turned turquoise green. Other edible mushrooms resembling the mushroom did not change color when the beam reagent (5 w/v% potassium hydroxide ethanolic solution) was dripped onto the mushroom pileus.

[Simultaneous Analysis of Paralepistopsis acromelalga Applied to Cooked and Processed Foods].

The applicability of a method for simultaneous analysis of Acromelic acids A, B, and Clitidine, which are venomous constituents of Paralepistopsis acromelalga, was assessed for three simulations: tempura, chikuzenni, and soy sauce soup. All components were detectable for all cooking methods. No interfering peak affecting the analysis was observed.

[Isolating Venomous Constituents of Paralepistopsis acromelalgaand Simultaneous Analysis of Its Compounds].

An isolation method for Acromelic acids A, B and Clitidine, which are venomous constituents of Paralepistopsis acromelalga was developed. Highly purified products were obtained from the mushroom extract using silica gel, ODS, ion-exchange column chromatography and preparative TLC. Using those results, we optimized the LC-MS/MS conditions.

[Aconitine analogues in wild Aconitum plants: contents toxicity to mice and decrease by boiling].

Simultaneous determination of four aconitine analogues (ACs) (AC; aconitine, HA; hypaconitine, JA; jesaconitine, MA; mesaconitine) in leaves and roots of wild Aconitum plants (Aconitum japonicum THUNBERG, Aconitum okuyamae Nakai) was carried out to elucidate the relation between toxicity to mice and ACs content determind by liquid chromatography tandem mass spectrometry. The total amounts of ACs in leaves, roots, petals and nectaries of Aconitum japonicum collected at Sagae-shi Tashiro were 5.9 μg/g, 928.

[Determination of illudin S in Omphalotus guepiniformis and foods that caused food poisoning by liquid chromatography with tandem mass spectrometry].

A simple method was developed for determination of illudin S in fungi (Omphalotus guepiniformis: poisonous mushroom) and a food that caused food poisoning, using liquid chromatography tandem mass spectrometry (LC/MS/MS). Illudin S in fungi and the food that caused food poisoning was extracted with methanol and then cleaned up with an Oasis HLB cartridge. LC separation was performed with an octadecylated silica column (Inertsil ODS-3, 2.

[Simultaneous determination of aconitine analogues in Aconitum plants and foods that caused food poisoning by liquid chromatography with tandem mass spectrometry].

A simple method for the simultaneous determination of four aconitine analogues (AC; aconitine, HA; hypaconitine, MA; mesaconitine, JA; jesaconitine) in Aconitum plants (Aconitum subcuneatum NAKAI) and a food that caused food poisoning was developed, using liquid chromatography tandem mass spectrometry (LC/MS/MS). Aconitine analogues were extracted with 1 mmol/L HCl and then cleaned up with an Oasis HLB cartridge. The LC separation was performed with an octadecylated silica column (Develosil ODS-HG-5, 2.

Relationship between airborne Cry j 1 and the onset time of the symptoms of Japanese cedar pollinosis patients.

Background: Some patients with Japanese cedar (JC) pollinosis already show pollinosis symptoms before the first day of the pollen season as determined by microscopic pollen counts.

Methods: Airborne pollen allergen (Cry j 1) levels were measured by electron spin resonance radical immunoassay, a highly-sensitive method for Cry j 1 with a sensitivity 10-100-fold higher than conventional enzyme-linked immunosorbent assay. The symptom data from patients with JC pollinosis were collected from a mobile phone site, "pollen check sheet", and the onset times of the patients' symptoms were analyzed.

[Identification of airborne pollen and airborne particles with pollen allergen (Cry j 1, Dac g) by aeroallergen immunoblotting technique].

After collection of airborne particles with a seven-day recording volumetric spore trap (Burkard model) using optically clear, pressure sensitive acrylic adhesive tapes, a dry PVDF membrane was pressed down firmly onto the adhesive tape, antigen-antibody reaction was performed in full contact with the tapes and PVDF membrane. Dark purple spots from airborne pollen allergens were examined under a light microscope to evaluate the form of pollens and particles wit h the antigenicity. It is clarified that identification of the form of pollens with the antigencity is possible not only pollens with the antigenicity but a pollen has already lost its shape, and it is also clarified that some airborne particular matters have the pollen antigencity.

Effect of methanol extract from flower petals of Tagetes patula L. on acute and chronic inflammation model.

The methanol extract of the florets of Tagetes patula (MEFTP) inhibited acute and chronic inflammation in mice and rats. MEFTP significantly suppressed hind-paw oedema induced by gamma-carrageenin in mice. Furthermore, MEFTP not only inhibited the hind-paw oedema induced by various acute phlogogens, such as histamine, serotonin, bradykinin and prostaglandin E1, but also suppressed the increase of vascular permeability by acetic acid, indicating that it primarily acts at the exudative stage of inflammation.
