Offen. DE 2722911 1 Dec 1977, 25 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07H015-26. PRIORITY: US 76-688275 20 May 1976. DOCUMENT TYPE: Patent CA Section: 16 (Fermentations) Section cross-reference(s): 11, 27, 1 Compds. of structure I, where X1, X2, X3, and X4 are H, OH, Cl, NH2, lower alkyl, or lower alkoxy groups and R and R1 are mono- or disaccharides, are prepd. by chem. synthesis, isolation from the tree Eucommia ulmoides, or by fermn. with Caldariomyces fumago. These compds. have antihypertensive properties. Thus, C. fumago was inoculated into flasks contg. 500 mL medium composed of soybean meal 5, dextrose 20, NaCl 5, K2HPO4 5, and yeast ext. 5 g/L. After 48 h at 25° with shaking, 2.5 g coniferyl alc. [458-35-5] dissolved in 4 mL DMF were added to each flask. After 16 addnl. h, the supernatant from 3 flasks were combined, acidified to pH 2.5, and extd. with EtOAc. The ext. was evapd. and the oily residue chromatographed on silica gel to yield 810 mg (±)-pinoresinol [4263-88-1] and 798 mg cis-dehydrodiconiferyl alc. [60536-58-5]. Pinoresinol diglucoside [63902-38-5] was prepd. in a 34% yield by reaction of pinoresinol with Ag2O and aceto-a-bromoglucose [572-09-8].

Journal of Liquid Chromatography & Related Technologies, 30(1), 135-145 (English) 2007 Taylor & Francis, Inc.Some commonly used reagents like 573-44-4 and 63902-38-5 are used in this experiment. CODEN: JLCTFC. ISSN: 1082-6076. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 11, 64 In this study, we reported a high throughout isolation procedure of pinoresinol diglucoside and liriodendrin from the traditional Chinese medical plant Eucommia ulmoides Oliv. by high speed countercurrent chromatog. The solvent system consisted of n-butanol-acetic acid-water(4: 1: 5, vol./vol./v), in which the lower phase was used as the mobile phase at a flow-rate of 2.0mL × min-1 in the head to tail elution mode. The method yielded 21 mg of pinoresinol diglucoside at 96.7% purity and 16 mg of liriodendrin at 95.5% purity from 200 mg of crude ext. in a one step. The purity and identity of the isolated compds. were checked by high performance liq. chromatog. anal., in combination with mass spectrometry, IR spectrum, and NMR measurements. .
