As the separation characteristics of liquid chromatographic and electrophoretic techniques markedly differ from each other, combined methods using the advantages of both procedures have been successfully used for the analysis of flavonoids. Thus, the use of CZE-UV, HPTLC-UV and GC-MS for the measurement of flavonoids in seeds and root exudates of Lotus pedunculatus has been reported. The rooting solution and seed exudate were passed through cellulose acetate filters to bind the flavonoids. After extraction,... 

The distribution of aluminum in the root tips of the aluminum-tolerant forage legume, Lotus pedunculatus Cav., a species that also accumulates condensed tannin (proanthocyani-din), has also been investigated. In osmium-fixed samples from high and low aluminum...

Many flavonoids are known to be phytoalexins, antiviral agents, and to serve as antiinflammatory and antitumor compounds. Several isoflavones have estrogenic activity in mammals (70). (-)-Vestitol and sativan, isoflavans from Lotus species, are phytoalexins. 3R(-)-Vestitol from the resistant pasture legume Lotus pedunculatus, has been demonstrated to be a feeding deterrent...

The tannin-containing vacuole may become very large and has been observed to occupy over 90% of the volume of Picea glauca cells (18) and also of tannin-containing cells in Pinus strobus needles (75). Tannins do not appear to be present in chloroplast cells and, in the case of Douglas-fir callus cell suspension cultures, some sort of metabolic balance appears to be struck between the chloroplast and tannin-producing cells. Too rapid production of the latter leads to death of the culture (H. A. Stafford, personal communication). Such specialized tannin cells have also been observed in Vitis vinifera phloem tissue and Lotus pedunculatus leaf and root tissues. Such a pattern may be the norm in the plant kingdom.

As in the preceding paragraph, the reactions of the former in anti-Pn VII, XIV, and anti-Mycop/. bovis are accounted for. Sophora gum was sent by Dr. E. L. Richards and also reacted with anti-Pn XIV, as did his sample of Lotus pedunculatus gum.
