According to the lengths of the stems attached to the hooks, Uncaria hooks were classified into four types as follows: Type 1: stem length = hook width Type 2: stem length=hook width × 2 Type 3: stem length = hook width × 3 Type 4: stems without hooks The alkaloid contents of Uncaria hooks of the 4 types were compared with each other. In the case of commercially obtained Uncaria hooks, the alkaloid contents were in the fol- lowing order: Type 3 > Type 4 > Type 2 > Type 1 In the case of Uncaria hooks prepared from U. rhynchophylla cultivated in the field, no significant difference was observed among the alkaloid contents of the three types (Type 1-3). When preparing Uncaria hooks from the cultivated Uncaria rhynchophylla, it is desirable to cut the stem at the center of the internodes to obtain the hooks, because the Uncaria hooks belonging to type 3 showed higher alkaloid contents.
