    • PROBLEM TO BE SOLVED: To obtain the subject antioxidant capable of strongly scavenging an active oxygen formed in vivo by a hydrolyzing type tannin by including a solvent extract of an insect gall of a plant belonging to the family of Fagaceae. SOLUTION: The objective antioxidant contains a solvent extract of an gall of a plant belonging to the family of Fagaceae (the insect gall has a science name of Quercus lustitanica Lamk and is formed by the stimulation caused when a female of gallfly lays eggs in bud of a high tree of the family of the Fagaceae) as an active ingredient. The solvent extract is obtained, for example, by adding a solvent, preferably ethanol, to a pulverized material of the insect gall, leaving the added material at a room temperature for several days, filtering the solution, and optionally purifying the filtrate by a column chromatography or the like. Especially, 1,2,3,6-tetra-O-galloyl-β-D-gLucose is preferable in the solvent extract. The antioxidant is widely usable for a food and drink, a medicine, a cosmetic or the like.

    • PROBLEM TO BE SOLVED: To propagate a tree belonging to genus Gmelina useful for a building material, etc., in a large amount for a short period of time by culturing a shoot apex of trees belonging to genus Gmelina, inducing and propagating a multibuds body having many (in)definite buds and regenerating a plant body under a specific condition. SOLUTION: A shoot apex of a tree belonging to genus Gmelina such as Gmelina arborea Roxb is cultured, a multibuds body having many (in)definite buds is induced and propagated, and a large amount of shoot is produced from the multibuds body, then the shoot is transplanted into a rooting medium such as a B5 medium containing 0.002mg/L of indolebutyric acid (IBA) with non- adding of a growth-regulating substance of plants, or together with 0.01-0.3mg/V of benzine aluminopurine (BAP), thus rooted and a plant body is regenerated, then a tree belonging to genus Gmelina is propagated in a large amount. Preferably, a B5 medium containing 0.01-0.3mg/L BAP or 0.01-0.3mg/L BAP with 0.002mg/L IBA, or its modified medium is used as a medium producing the shoot.
