[Table] As a result, the sesquiterpenoid compound represented by the above structural formula () has a strong anti-ulcer effect against restraint water immersion stress ulcers. (b) Acute toxicity As described in JP-A-57-163373, one group of 15 ddY male mice weighing 18 to 20 g was used.
When the test drug was orally administered to animals and the LD 50 was calculated from the number of deaths over 3 days, the LD 50 (mg/Kg) (95% confidence limit) was 590.0 (430.7-808.3). From the above, the compound of the above structural formula () exerts its anti-ulcer effect when administered orally;
When used for treatment, the dosage is 80mg once, 2 to 2 times a day.
It is estimated that it is effective after taking it about three times. For administration, it is preferable that the drug be supplied in a form suitable for absorption by the digestive system, and can be used in a conventional manner with any required pharmaceutical carrier or excipient. Effects of the Invention As explained above, according to the present invention, it has been found that the compound represented by the above structural formula () has an anti-ulcer effect, and thereby it is possible to provide an anti-ulcer therapeutic agent containing this compound as an active ingredient. . If this anti-ulcer therapeutic agent is made from crude drugs, its toxicity has already been proven to some extent, so it is possible to provide a drug with high reliability in terms of safety. Examples The following is a detailed explanation based on examples. As shown in Figure 2, Yakushima-produced gajiyutsu (dry flakes, 10.8 kg) are extracted by digestion (water bath, 50°C) with methanol (20) for 7 hours. The same operation was repeated 9 times, the methanol extracts were combined, and the solvent was distilled off under reduced pressure to obtain the methanol extract (abbreviated as YK-1, yield 1.12 kg, yield 10.4% from crude drugs, the same applies hereinafter). Obtained. Dissolve YK-1 (200 g) in methanol (600 ml) and extract three times with hexane (3). Remaining
A portion (800 g) of YK-1 was also subjected to methanol-hexane partition extraction. The methanol layers were combined, the solvent was distilled off under reduced pressure, and the methanol layer extract (YK-

14.3g, 0.46%), 6th fraction (YK-6, 11.8
g, 0.38%), 7th fraction (YK-7, 6.5 g, 0.21
%), and the eighth fraction (YK-8, 22.9 g, 0.74%) was obtained from the chloroform:methanol=10:1 eluate. YK-4 (10 g) was subjected to silica gel chromatography [Silica gel; 500 g (manufactured by MERCK,
Kieselgel60), elution solvent; hexane-ethyl acetate system (hexane:ethyl acetate = 50:1, 30:1,
0.5 of each in the order of 25:1], then the solvent in the eluted portion with the elution solvent of hexane:ethyl acetate = 25:1 was distilled off under reduced pressure, and the colorless product was fractionated by recrystallization with hexane.
