Studies on different growing periods of Panax ginseng, its ages and the variation regularities of amino acids in its main organs are reported. The test has shown that it contains seventeen amino acids. The total amount of amino acids reaches its peak point during the sprouting period (in April), next to it is the withering period (in September), flowering and fruiting periods being the lowest (in June). The amount of these acids in the main root is higher than that in the fibrous root, the lowest being in the lateral root. Five-year-old Panax ginseng features the highest amount.
报道了人参不同生长时期、不同年龄及其主要器官中氨基酸的变化规律。试验表明，人参含有17种氨基酸。氨基酸总量在萌芽期（4月）达到峰值，其次是枯萎期（9月），开花结果期最低（6月）。主根中这些氨基酸的含量高于须根，侧根中最低。5年生人参的氨基酸含量最高。
