External leaf flavonoids of Thymus species from Macedonia

External leaf flavonoids of Thymus species from Macedonia. Marin, P.In this study， 437-64-9 and 13509-93-8 are also used. D.; Grayer, R. J.; Kite, G. C.; Matevski, V.

DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) Section cross-reference(s): 27 External flavonoids of 40 Macedonian species and infraspecific taxa of Thymus, belonging to sections Marginati, Pseudothymbra and Serpyllum, were studied by HPLC combined with diode array detection and atm. pressure chem. ionisation mass spectrometry. Nineteen different flavones were identified and the most common and abundant compd. was 5,6-dihydroxy-7,3',4'-trimethoxyflavone. Most species also produce surface flavanones, including eriodictyol, naringenin and isosakuranetin. The external flavonoid profiles found in species of Thymus provide useful addnl. taxonomic characters at various different levels of classification. .

Constituents of Broussonetia papyrifera Vent

Constituents of Broussonetia papyrifera Vent. Liang, Pi Wei; Chen, Chien Chih; Chen, Yuh Pan; Hsu, Hong Yen (Brion Res. Inst. Taiwan, Taipei 10743, Taiwan). Hua Hsueh, 44(4), 152-4 (Chinese) 1986. CODEN: HUHSA2. ISSN: 0441-3768. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) B. papyrifera Is a Moraceous plant which yields a white juice from its stem or branch bark and leaves. It is used as a folk medicine in treating ringworm with marked effect. Its fruit is known as Che Shih, which is used for treating achy loin and knees, abdominal edematous distention, blood asthenia with blurring vision, etc. From the ethanol ext. of the stem of this plant, after silica gel column chromatog., four cryst. compds.There are some commonly used reagents with their cas registry numbers 13849-08-6 and 437-64-9 in this article. were obtained. The compds. were identified as betulinic acid [472-15-1], ursolic acid [77-52-1], genkwanin [437-64-9], and marmesin [13849-08-6]. .
