 Title    A M yricetin Tetram ethyl Ether from the L eaf and Stem Surfaces o f Tillandsia usneoides  
 Abstract    Myricetin-3,7,3',4'-tetramethyl ether has been isolated as an aglycone from the acetone wash of Tillandsia usneoides. It is thus shown to be deposited externally, on leaf and stem surfaces. We suggest that the previously re­ ported lipophilic flavonoids from this and other species are also exudate constituents.

 Title    FTIR Study of the v 12 and the v 12 + v 14 — v 14 Bands of 1,3,5-Triazine Near 740 cm -1  
 Abstract    The infrared spectrum of the v 12 fundamental and its accompanying hot band v 12 + v 14 — v 14 of triazine has been measured by means of a Fourier transform spectrometer with a resolution of about 0.0023 cm" 1 . A total of about 2779 rovibrational transitions has been assigned. The ground state constants have been considerably improved whilst the parameters for the excited states tf 12 =l, i; 14 = l and tf 12 =i> 14 = l have been obtained for the first time. The standard deviations were 2.92 • 10" 4 cm" 1 for the ground state constants and 1.53 • 10" 4 cm 1 for the excited state parame-ters of v 12 showing the latter to be unperturbed. The upper state of the hot band v 12 + v 14 — v 14 was found to be perturbed by an accidental resonance.

 Title    Degradation of Pentachlorophenol by Mycena avenacea TA 8480 - Identification of Initial Dechlorinated Metabolites  
 Abstract    Cultures o f the basidiomycete M ycena avenacea TA 8480 were shown to m etabolize penta­ chlorophenol (PCP), 2,3,5,6-tetrachloro-/7-hydroquinone (TeCHQ), and 2,3,5,6-tetrachloro-/?-benzoquinone (TeCBQ). The first metabolite o f the PCP degradation pathway was identified as TeCBQ which in a second reaction is reduced to the hydroquinone TeCHQ. Subsequently dechlorination o f TeCHQ yielded 3,5,6-trichloro-2-hydroxy-/?-benzoquinone (TCOHBQ). The specific degradation rate for PCP was 1.4 mg x g dry m ycelia-1 x day-1. The initial de­ chlorination rate o f TeCHQ was 5.9 mg x g dry m ycelia"1 x h o u r '1. N one o f the com pounds supported growth o f the fungus.
