从远东疣柄牛肝菌(Leccinum extremiorientale)子实体中提取分离得到13个 化合物,通过理化常数和波谱数据分析,它们的结构被鉴定为:麦角甾-7,22-二 烯-3β,5α,6β-三醇(1),麦角甾醇过氧化物(2),麦角甾醇(3),麦角甾 -4,6,8(14),22-四烯-3-酮(4),麦角甾-5,7-二烯-3β-醇(5),棕榈酸 (6),(2S,3S,4R,2’R)-2-(2’-羟基二十四碳酰胺)十八烷-1,3,4-三 醇(7),脑苷脂B(8),脑苷脂D(9),尿嘧啶(10),肌苷(11),腺苷(12 ),D-阿洛醇(13),利用2D NMR(~1H-~1H COSY,HMBC,HMQC)技术首次对化合 物8和9的氢谱和碳谱数据进行了全归属。在浓度为100 μg/mL时,化合物2,7和8 表现出选择性地抗蛇毒Crotalus adamenteus分泌的磷脂酶A_2活性,而对蜂毒 Apis mellifcra磷脂酶A_2却无活性。此外,远东疣柄牛肝菌提取物对粘虫拒食率 和小莱蛾死亡率分别为67%和55%。

Thirteen chemical constituents were isolated from the fruiting bodies of basidiomyctes Leccinum extremiorientale, and their structures were elucidated by spectral and physical-chemical data as: ergosta-7,22-dien-3/3,5ff,6/?-triol (1), ergosterol peroxide (2), ergosterol (3), ergosta-4,6,8(l4) ,22-tetraen-3-one (4), ergosta-5, 7- dien-3/3-ol (5), palmitic acid (6), (2S, 3S, AR, 2'R)-2-(2'- hydroxytetracosanoylamino) octadecane-1,3,4-triol (7), cerebroside B (8) , cerebroside D (9), uracil (10), inosine (11), adeosine (12) and D- allitol (13). The NMR data of compounds 8 and 9 were completely assigned by 2D-NMR techniques, including 'H^H COSY, HMBC and HMQC. Compounds 2, 7 and 8 at concentration of 100μg/mL showed selectively inhibitory activity against phospholipase A2 (PLA2) secreted from Crotalus adamenteus venom, but inactive against PLA2 of bee venom (Apis mellifcra). In addition, the methanol-chloroform soluble extract of this fungus also showed 67% antifeedant rate against Leucaninia separata and caused 55% mortality against Plutella xylostella after three-day application.
