    Notes: Abstract Geographic and demographic characteristics of the 120 Kentucky counties were utilized to group counties with similar characteristics. Factor analysis and then cluster analysis were used to establish four county groupings. ACT test results and demographic data, and enrollment data for 1977, 1978, 1979, and 1980 for those 1977 high school graduates enrolled in Kentucky state-supported colleges and universities, fall semester 1977, were analyzed to determine whether geographic origin influenced college attendance. Four hypotheses tested enrollment, persistence, and transfer activities; college-going rates; and academic achievement of students. Test results revealed significant differences and the null hypotheses were rejected.

    Description / Table of Contents: Triterpenes, XXXIII. On the Saponin of the Flowers of Verbascum phlomoides L.From the flowers of Verbascum phlomoides L. a saponin verbascosaponin (1), C54H90O22, was isolated containing as aglycone verbascogenin, C30H50O4, with one double bond. At acidic conditions it is transformed into the known triterpene A (2), C30H48O3, with two double bonds2,3. Four sugar units were found in the glycoside  -  2 D-glucose, 1 L-rhamnose and 1 D-fucose. The sequence of the sugar chain was determined.
    Notes: Die Blüten von Verbascum phlomoides L. liefern das Saponin Verbascosaponin (1), C54H90O22, das als Aglycon Verbascogenin, C50H50O4, mit einer Doppelbindung enthält. Bei Säureeinwirkung entsteht das bekannte Triterpen A (2) mit der Summenformel C30H48O3 und zwei Doppelbindungen2,3). Im Glycosid wurden vier Zucker gefunden  -  2 D-Glucose, 1 L-Rhamnose und 1 D-Fucose  -  und die Art ihrer Verknüpfung bestimmt.
