Betaine is a useful compound that has various activities and is the marker compound of fruit in Korean Pharmacopoeia. we seek to support the stable production of medicinal goji berries, which have significant potential in the pharmaceutical industry due to their high values, and to provide foundational data for consistent quality control. This study's purpose was to examine the correlation among betaine content, environmental variables, and the growth characteristics of fruits. The fruits were collected from 25 cultivation sites across South Korea. We investigated five growth characteristics and betaine contents in fruits and twelve soil physicochemical properties, and seven meteorological data at cultivation sites. The fruit's growth characteristics included a length of 15.62-26.49 mm, a width of 7.09-11.38 mm, a fresh weight of 0.73-1.62 g, and a sugar content of 11.10-19.62 Brix°. Its betaine content ranged from 0.54% to 0.97%. The betaine content was positively correlated with electrical conductivity (0.327 **), exchangeable potassium (0.314 **), and sodium (0.259 *) and negatively correlated with annual average minimum temperature (-0.256 *) and annual average temperature (-0.242 *). Also, betaine showed a positive correlation with the length of the fruit (0.294 *) and the fresh weight of the fruit (0.238 *). These results can be used to find the best cultivation method and to manage quality control for the highly economical fruit.
甜菜碱是一种具有多种活性的有用化合物，是《韩国药典》中水果的标志性化合物。我们旨在支持药用枸杞的稳定生产，因其高价值在制药行业具有巨大潜力，并为一致的质量控制提供基础数据。本研究的目的是研究甜菜碱含量、环境变量与果实生长特性之间的相关性。果实从韩国各地的25个种植地点采集。我们调查了果实的五个生长特性和甜菜碱含量、十二种土壤理化性质以及种植地点的七个气象数据。果实的生长特性包括长度为15.62 - 26.49毫米、宽度为7.09 - 11.38毫米、鲜重为0.73 - 1.62克以及糖含量为11.10 - 19.62°白利糖度。其甜菜碱含量范围为0.54%至0.97%。甜菜碱含量与电导率（0.327 **）、交换性钾（0.314 **）和钠（0.259 *）呈正相关，与年平均最低温度（-0.256 *）和年平均温度（-0.242 *）呈负相关。此外，甜菜碱与果实长度（0.294 *）和果实鲜重（0.238 *）呈正相关。这些结果可用于找到最佳种植方法并管理这种高经济价值果实的质量控制。
