Desoxocamoensidine was isolated from Maackia amurensis Rupr. and Maxim. (187). The structure of the alkaloid (164) was established by its identity with the product obtained from camoensidine (159) with LAH (Scheme 28).

Plants from three different families, viz. Arecaceae, Fabaceae, and Gnetaceae, have so far been found to elaborate stilbenolignans. The individual plants known to yield stibenolignans are listed in Table 18. Fig. 30 shows an image of Maackia amurensis. 

Maackolin, C25H24O8, isolated from Maackia amurensis, was identified as 8-epi-8 -epi-3-de-0-methyl-5 -methoxygnetifolin F (143), based on the spectroscopic comparison between maackolin pentacacetate and gnetifolin F tetraacetate, and NOE difference NMR experiments on maackolin (755). Lehmbachol D (142), isolated from G. cleistostachyum, is structurally similar to 143 and it possesses a methoxy group in place of the hydroxy group at the C-3 position. The NOE correlation of H-8 and H-8 indicated their mutual cis orientation. The biomimetic synthesis of 142 has also been described (752) (Scheme 11).

Carbohydrate chains of Cl-inhibitor were identified by a binding assay using different lectins [36]. Lectins from Sambucus nigra (SNA) and Maackia amurensis (MAA), that are specific for sialic acids, were shown to bind to Cl-inhibitor. Lectin from Datura stramonium (DSA) also reacted with the inhibitor indicating complex and hybrid sugar structures. Cl-inhibitor was enzymatically desialylated and reexamined for lectin binding. SNA and MAA did not react anymore, but in addition to DSA, peanut agglutinin, which can bind to carbohydrate chains after sialic acids are removed, bound to desialylated Cl-inhibitor. Cl-inhibitor contains about 30 sialic acid residues per molecule. SDS-...
