    Notes: Abstract The solar wind in the inner heliosphere, inside ~ 5 AU, has been almost fully characterized by the addition of the high heliographic latitude Ulysses mission to the many low latitude inner heliosphere missions that preceded it. The two major omissions are the high latitude solar wind at solar maximum, which will be measured during the second Ulysses polar passages, and the solar wind near the Sun, which could be analyzed by a Solar Probe mission. Here, existing knowledge of the global solar wind in the inner heliosphere is summarized in the context of the new results from Ulysses.

    Description / Table of Contents: Zusammenfassung Es wird über das Verhalten von 2-Phenylpropan-1-ol (I) und 2-Phenylpropan-2-ol (II) (beide sind Metaboliten von Cumol) und ihrer Glucuronide gegenüber HCl berichtet. Während I eine hohe Säurebeständigkeit aufweist, erfährt II eine Umwandlung in 2-Phenylpropen (III), aus dem durch Folgereaktionen zahlreiche Produkte entstehen. Die glykosidische Bindung des I-Glucuronides wird mit 10,0% HCl quantitativ gespalten, wobei eine Aglykonausbeute von nahezu 100% erzielt wird. Anders verhält sich das II-Glucuronid: die Wiederfindungsraten an II liegen mit nur 40 bis 45% im gesamten HCl-Konzentrationsbereich (1,0% bis 20,0%) sehr niedrig, obwohl schon mit 1,0% HCl eine Hydrolyserate des Glucuronides von 100% erreicht wird.
    Notes: Summary The behaviour of 2-phenyl-1-propanol (I) and 2-phenyl-2-propanol (II) and their glucuronides with HCl has been investigated. While I shows a high acidic constancy, II undergoes a partial conversion into 2-phenylpropane (III) which itself yields numerous products. The glucosidic bond of glucuronide I is quantitatively split by 10.0% HCl, whereby an aglucone yield of nearly 100% is obtained. The second glucuronide behaves otherwise: the recovery of II is very low (only 40% to 45%) with HCl concentrations of 1.0%–20.0%, although with 1.0% HCl 100% of the glucuronide is hydrolysed.
