喇叭茶醇是一种天然有机化合物,以下从化学特性、物理性质及来源用途三方面进行详细解释:
基本信息
中文名称为喇叭茶醇,又称喇叭茶脑,属于萜类化合物。其分子式为C₁₅H₂₆O,分子量222.37。存在两种CAS号争议:(577-27-5)和(5986-49-2),可能源于立体异构体差异。立体化学结构显示为多环萜醇,如(1aS,4S,4aR,7S,7aR,7bR)-十氢-1,1,4,7-四甲基环丙基奥菊烯-4-醇。
化学性质
呈弱碱性,酸度系数pKa≈15.20±0.70;LogP值为4.738(估算值),表明具有较强亲脂性。
外观与溶解性
针状结晶,易升华(低于熔点即升华),微溶于水,溶于乙醇及多数有机溶剂(约10g/100ml乙醇)。
热力学参数
熔点104-105℃,常压沸点292℃,减压条件下(3 Torr)沸点降至131-133℃。密度0.9646 g/cm³,旋光度[α]²⁰_D为+28°(氯仿溶液)。
天然来源
主要从杜鹃花科植物喇叭茶(Ledum palustre)中提取,属于植物次生代谢产物。
应用领域
作为中药标准品使用,可能具有药用研究价值。其具体生物活性及工业用途需进一步研究验证。
注:CAS号差异需谨慎核对,建议通过权威化学数据库(如SciFinder)确认具体结构。
