Twelve new diarylheptanoids and six known compounds were isolated from rhizomes of Curcuma kwangsiensis. Structures of the new compounds were elucidated by spectroscopic and chemical methods as (3S)- and (3R)-1,7-bis(4-hydroxyphenyl)-(6E)-6-hepten-3-ol (1a and 1b), (3S)- and (3R)-1-(3,4-dihydroxyphenyl)-7-(4-hydroxyphenyl)-(6E)-6-hepten-3-ol (2a and 2b), (3S)- and (3R)-1-(3,4-dihydroxyphenyl)-7-(4
从姜黄的根茎中分离出12种新的二芳基庚烷类化合物和6种已知化合物。通过光谱和化学方法阐明了新化合物的结构,分别为(3 S)-和(3 R)-1,7-双(4-羟苯基)-(6 E)-6-庚烯-3-醇(1a和1b),(3 S)-和(3 R)-1-(3,4-二羟基苯基)-7-(4-羟基苯基)-(6 E)-6-庚烯-3-醇(2a和2b), (3 S)-和(3 R)-1-(3,4-二羟基苯基)-7-(4-羟基苯基)庚烷-3-醇(3a和3b),(3 R)-1-(3,4-二羟基苯基)-7-苯基-(6 E)-6-庚烯-3-醇(4b),(3 S)-和(3 R)-3-乙酰氧基-1-( 3,4-二羟基苯基)-7-(4-羟基苯基)-(6 E)-6-庚烯(5a和5b),(3 S)-和(3 R)-3-乙酰氧基-1-(3,4 -二羟基苯基)-7-(4-羟基苯基)庚烷(6a和6b)和(E)-1,7-双(4-羟基苯基)-6-庚
