Hydrophilic extracts of Scots pine (Pinus sylvestris L.) twigs have been investigated for palatability to moose in feeding experiments. The predominant repellent effect was observed from the 2-O-β-D-glucopyranoside of the monoterpene (1S,2R,4S,5S)-angelicoidenol. Of other isolated and tested substances, only taxifolin-3'-O-β-D-glucopyranoside had a deterring effect. One fraction-containing mainly aliphatic compounds-also had a strong effect, but the effect was lost after further fractionation. Tannin-containing fractions had no effect. Angelicoidenol glucoside has not previously been reported fromP. sylvestris. The results are discussed in view of phenols as defense compounds.
水松枝的亲水提取物在饲养实验中被研究对驼鹿的适口性。从单萜（1S,2R,4S,5S）-当归醇的 2-O-β-D-吡喃葡萄糖苷观察到主要的驱避作用。在其他分离和测试的物质中，只有 taxifolin-3'-O-β-D-吡喃葡萄糖苷具有驱避作用。主要含有脂肪族化合物的一个馏分也具有很强的作用，但进一步分级后作用消失。含单宁的馏分没有作用。糖苷 Angelicoidenol 以前从未在 P. sylvestris 中报道过。这些结果从酚类化合物作为防御化合物的角度进行了讨论。
