摘要：
Triterpenes and triterpene glycoside compounds (I) are new. Triterpenes and triterpenes glycoside compounds of formula (I) and their salts are new. R1-R4 : H or a sugar residue comprising a monosaccharide residue or oligosaccharide residue； and dotted line : a single or a double bond, where the counterion of the salt of (I) is single positive charged cation of the first main group and subgroup, ammonium ion, trialkylammonium ion, bivalent charged cations of the second subgroup, trivalent cations of the third main and subgroups, preferably Na +>；, K +>；, NH 4 +>；, Ca 2+>；, Mg 2+>；, Al 3+>；or Zn 2+>；. Independent claims are included for: (1) a mixture comprising two or more (I)； (2) plant extracts, preferably plant extracts of Mycetia balansaecomprising (I) or the mixture, where the amount of (I) is 0.00001-99 (preferably 0.001-30) wt.%, relative to the dry mass of the extracts； (3) preparing the extracts, comprising single or multiple extraction of plant material of Mycetia balansaewith a liquid, extraction agent comprising water, ethanol, methanol, 1-propanol, 2-propanol, glycerin, 1,2-propanediol, supercritical carbon dioxide and/or ethyl acetate, and optionally concentrating the obtained primary extract by one or more evaporative or pervaporative methods, optionally treating the optionally concentrated primary extract with adsorbents comprising optionally modified silica gel, activated carbon, zeolite, bentonite, diatomaceous earth, alumina, basic, acidic or neutral, optionally macroporous, ion exchangers, preferably in batch or column method, optionally with further extraction aid to obtain a purified extract (secondary extract), optionally drying the secondary extract by evaporative or pervaporative process, and optionally mixing the dried secondary extract with two or more diluents comprising ethanol, isopropanol, 1,2-propylene glycol, vegetable oil triglycerides, diacetin, triacetin or glycerin, to obtain a solution； (4) a preparation that is ora
