Abstract: The object of the present invention is to provide a ginsenoside composition which can obtain specific and excellent result in terms of efficacy, to various symptoms and diseases. The ginsenoside composition includes 3 components of Rb 1, Rg 3 (S), and Rg 2(S), which are ginsenosides, as an essential component. In solid base of the composition, the ginsenoside composition satisfies the following 3 requirements. That is, (Requirement 1): a content of the Rb 1 is 7.3 mg/g or more, (Requirement 2): a ratio of a content of the Rb 1 and a content of the Rg 3 (S), “Rb 1/Rg 3 (S)”, is in a range of 1.2 to 3.7, and (Requirement 3): a ratio of a content of the Rg 3 (S) and a content of the Rg 2 (S), “Rb 3 (S)/Rg 2 (S)”, is in a range of 1.7 to 4.4.

Abstract: An inverter operation command apparatus having increase and decrease keys which, when operated according to predetermined requirements, allows the frequency to be set quickly, requires only the increase/decrease key to be actuated to determine the rotation of direction and run/stop of the inverter, and allows the frequency display to be changed. Actuation of increase and decrease keys in predetermined orders, for predetermined durations and at predetermined times, in accordance with predetermined subroutines, will permit flexible control of the inverter frequency.

Abstract: Disclosed is a method for producing an angiotensin converting enzyme inhibitor composition from natural materials, which composition is of use as an antihypertensive drug or diet. The method comprises heating a meat in water at a temperature not lower than 50.degree. C. to extract water-soluble protein and hydrolyzing the residue predominantly composed of water-insoluble protein with a protease.

Abstract: A method of producing an angiotensin converting enzyme inhibitor-containing composition, which is of value as an antihypertensive agent or diet, from natural resources. According to the method, proteins are hydrolyzed with a protease elaborated by a microorganism of the genus Bacillus, Aspergillus or Rhizopus or a protease of papaya origin.

Abstract: A process for preparing sorbic acid which comprises treating sorbic aldehyde with at least one microorganism selected from Mycobacterium, Rhodopseudomonas, Streptomyces, Acetobacter, Alcaligenes and Gluconobacter. According to the present invention, sorbic acid can be prepared in high yield by oxidizing sorbic aldehyde with the specific microorganism.

Abstract: A process for preparing an optically active .gamma.-halo-.beta.-hydroxybutyric acid ester in high yields which comprises subjecting a .gamma.-haloacetoacetic acid ester to the action of a microorganism selected from genus Saccharomyces under an anaerobic condition. When the .gamma.-haloacetoacetic acid ester is subjected to the action of the microorganism in the presence of a ketal, the yield and optical purity can be further increased.
