摘　　要：目的　报道诃子中 3种主要可水解丹宁 :诃子酸 (chebulinicacid)、诃黎勒酸 (chebulagicacid)及chebulanin的波谱数据。方法　利用凝胶色谱技术从诃子中分离得 3种成分 ,应用1H 1HCOSY、HMQC及HMBC技术归属其NMR信号。结果　得出了 3种成分的UV、IR、1H和13CNMR数据。结论　首次对上述 3种成分的13CNMR信号进行了明确归属。AIM\ The aim is to spectroscopic data of the main hydrolyzable tannins from the fruits of \%Terminalia chebula\%: chebulinic acid, chebulanin and chebulagic acid. METHODS\ Using combined chromatographies over Diaion HP 20, Toyopearl HW 40 and MCI gel CHP 20P to purify the above three constituents and assigning their NMR signals by means of 1H 1H COSY, HMQC and HMBC techniques. RESULTS\ The UV, IR, \+1H and 13 CNMR data of the above three compounds were given in detail. CONCLUSION\ The 13 CNMR data of the above three compounds were assigned for the first time.
