The present invention relates to Semblan-type diterpene compounds. Sembran-type diterpenes are found in coelenterates belonging to the orders Gorgonacea and Alcyonacea, and have recently been found to have antitumor activity, and have attracted attention. [For example, B. Tursch et al., Tetrahedron, Vol. 31, p. 129, 1975;
United Kingdom and Weinheimer (AJ
Weinheimer et al., Tetrahedron Letters, p. 2923, 1977, UK.] In view of these circumstances, the present inventors focused on the coelenterate Sarcophyton glaucum, which belongs to the order Cylindriformes. As a result of intensive research, a new Semblan-type diterpene compound was discovered and the present invention was achieved. The present invention will be explained in detail below. The compound according to the present invention has the general formula () (In the formula, R represents a hydrogen atom or an acetyl group.) This is a Semblan-type diterpene compound represented by the following formula. In the present invention, a compound represented by the general formula () in which R is a hydrogen atom is named Sarcophytol-A. Further, when R is an acetyl group, it is referred to as sarcophytol-A acetate. The compound according to the present invention can be extracted from, for example, the giant mushroom. The compound according to the present invention can be separated from the lipid fraction of the extract of Arum mushroom by silica gel column chromatography. Giant sea mushrooms usually live in the coral reefs of the Indian and Pacific Oceans, for example, the giant sea mushrooms that live in the Red Sea contain sarcophine and
It is known to contain 16-deoxosarcofin. [See J. Bernstein et al., Tetrahedron Vol. 30, p. 2817, 1974, UK and Y. Kashman et al., Tetrahedron, vol. 30, p. 3615, 1974, UK]] Contained in the giant mushroom The components to be collected may differ depending on the time and place of collection, so it is necessary to select them appropriately. During extraction, it is preferable to dehydrate and shred to such an extent that the surface loses its viscosity. Examples of extractants include alcohols such as methanol, ethanol, and isopropanol; halogenated hydrocarbons such as chloroform; hydrocarbons such as benzene, hexane, and heptane; ethyl ether,
Examples include organic solvents such as ethers such as isopropyl ether and dioxane; ketones such as acetone and methyl ethyl ketone; and esters such as ethyl acetate; or mixed solvents thereof. During the extraction operation, to avoid decomposition of the contained components,
It is preferable to minimize the contact area with air or to use an inert gas atmosphere. Extraction can be carried out at room temperature, but in order to speed up the extraction, it may be carried out under heating. The extract obtained by separating the residue by a conventional method is
A crude extract can be obtained by distilling off the solvent using a conventional method. Crude extracts can be prepared using conventional methods [e.g. J.Folch].

Vol. 497, 1957, United States Reference]
It can be fractionated into lipid fractions. The property of the lipid fraction of the extract of the giant sea mushroom thus obtained is a viscous brown oil. Further purification may be achieved by chromatography. The chromatography may be either column chromatography or preparative thin layer chromatography. As a packing material for column chromatography,
Silica gel, alumina, cellulose powder, activated carbon, etc. are used. The elution solvent may be appropriately selected depending on the filler, but when silica gel is used as the filler, a mixed solvent of hexane-benzene is suitable. The mixing ratio of hexane and benzene is preferably about 3:1 to 1:1 (volume ratio). Further, the crude fraction obtained here can be further purified and isolated by column chromatography by changing the packing material and elution solvent. Silica gel, alumina, cellulose powder, etc. are used as the gel for preparative thin layer chromatography. As the developing solvent, chloroform or a chloroform-ether mixed solvent is suitable. Furthermore, when sarcophytol-A is acetylated by a conventional method, sarcophytol-A acetate is produced, and when sarcophytol-A acetate is further esterified by a conventional method, sarcophytol-
A is obtained. Since the compounds related to the present invention are susceptible to air oxidation, care must be taken when handling and storing them. The compounds according to the present invention are useful as pharmaceuticals. That is, as shown in the application example, the compound related to the present invention is effective against murine leukemia-P-388.
It is effective against tumor cells and holds great promise as an anti-leukemia drug. Furthermore, the compounds according to the present invention are useful as intermediates for pharmaceuticals, agricultural chemicals, and the like. EXAMPLES The present invention will be described in more detail with reference to Examples below, but the present invention is not limited by the Examples unless it exceeds the gist thereof. Example 1 17 kg of giant sea mushrooms collected in June 1972 on Ishigaki Island, Okinawa, were roughly dehydrated, chopped into small pieces, and thoroughly brought to room temperature with 40 parts methanol and then 30 parts chloroform-methanol (volume ratio 2:1). Extract. The solvent of the extract was distilled off under reduced pressure. The dry weight of the extraction residue was approximately 5.5 kg. Next, the method of Folch et al. [J. Folch et al., Journal of Biological Chemistry (J. Biol.
Chem.) Vol. 226, p. 497, 1957, USA]. In this way, 1.6 kg of viscous brown oily lipid fraction is obtained. 400 g of the lipid fraction was dissolved in hexane and separated by column chromatography using 2.5 kg of silica gel (manufactured by Merck & Co., Ltd., 70-230 mesh). The relationship between the elution solvent and each fraction is shown in Table 1.

た。[Table] The mixing ratio of elution solvents is shown by volume. (Similarly below) The fraction B thus obtained is purified by column chromatography using silica gel. Using 30 times the volume of silica gel, dissolve fraction B in the minimum amount of hexane and elute with a mixed solvent of hexane-chloroform. Sarcophytol-A acetate is eluted with hexane-chloroform (5:1), and sarcophytol-A is eluted with hexane-chloroform (1:1). The yields of sarcophytol-A and sarcophytol-A acetate were 35% of the lipid fraction, respectively.

This was confirmed by thin layer chromatography, infrared spectrum, PMR spectrum, and mass spectrometry. Example 3 Sarcophytol-A acetate was heated to reflux in a 5% potassium hydroxide methanol solution for 2 hours.
The production of sarcophytol-A was confirmed by thin layer chromatography and infrared spectroscopy. Test example Mouse leukemia Effect on P-388 P-388 cells were transplanted and subcultured, ascites 7 days after transplantation was diluted with physiological saline, and 1×10 6 cells per mouse were intraperitoneally transplanted. .
