摘要：
The present invention relates to high purity (-) Hydroxycitric acid metal salt derivatives of more than 98% purity having formula Il (a-e), lla; X, 2X = Na Mb; X, 2X= K Hc; X = K, Y = Ca Hd1 X= Na, Y = Ca He; X= 1 /2 Mg, Y = Mg and the method of preparation of high purity (-) hydroxycitric acid metal salt derivatives from (-) hydroxycitric acid lactone having formula (1 ) which in turn is isolated in a simple and efficient manner from dried rinds of the fruits of Garcinia species. This invention employes the HPLC method and optical rotation in assessing the purity (-) hydroxycitric acid and corresponding lactone (1 ).
摘要（中）：
本发明涉及具有式II（a-e），11a的纯度高于98％的高纯度（ - ）羟基柠檬酸金属盐衍生物; X，2X = Na Mb; X，2X = K Hc; X = K，Y = Ca Hd1 X = Na，Y = Ca He; X = 1/2 Mg，Y = Mg以及制备具有式（1）的（ - ）羟基柠檬酸内酯的高纯度（ - ）羟基柠檬酸金属盐衍生物的方法，其依次以简单有效的方式从 藤本果实的干果皮。 本发明采用HPLC方法和旋光度来评估纯度（ - ）羟基柠檬酸和相应的内酯（1）。
