Craib. is an indigenous plant found in Thailand, Cambodia and Vietnam that has become threatened owing to lack of knowledge about its agricultural management. This plant is now rare in the wild and was registered in the Plant Genetic Conservation Project under the initiation of Her Royal Highness Princess Maha Chakri Sirindhorn (RSPG) to promote sustainable conservation and optimally beneficial utilization. has a long history of utilization as a nutrient-rich source with medicinal properties but scientific evidence of the veracity of these claims is limited. Here, the nutritional compositions, phenolic contents and antioxidant activities of different plant parts (young shoots and old leaves) of were investigated using plants collected from four areas of Thailand as Kamphaeng Phet (KP), Muang Nakhon Ratchasima (MN), Pakchong Nakhon Ratchasima (PN) and Uthai Thani (UT) at different harvesting periods (March-April, May-June and July-August). Results indicated that young shoots provided higher energy, protein, fat, dietary fiber, phosphorus, sodium, and zinc than old leaves. By contrast, nutrients such as total sugar, vitamin C, carotenoids, potassium, calcium, magnesium, and iron contents were higher in old leaves that also exhibited higher phenolic contents and most antioxidant activities than young shoots. Generally, most nutrients, phenolic contents, and antioxidant activities exhibited no clear trend among different plant origins. The harvesting period of July-August provided a suitable climate for biosynthesis of most nutrients, while high phenolics were mainly found in samples harvested in March-April. No clear trend was observed in the prevalence of antioxidant activities that varied according to assay techniques.
Craib.是一种原产于泰国、柬埔寨和越南的本土植物，由于缺乏对其农业管理的了解，已受到威胁。这种植物现在在野外很罕见，并在诗琳通公主殿下发起的植物遗传保护项目（RSPG）中登记，以促进可持续保护和最优利用。它作为一种具有药用特性的营养丰富的来源有着悠久的利用历史，但这些说法真实性的科学证据有限。在此，使用从泰国四个地区（甘烹碧（KP）、呵叻府直辖县（MN）、呵叻府巴冲县（PN）和乌泰他尼府（UT））在不同收获期（3月至4月、5月至6月和7月至8月）采集的植物，对Craib.不同植物部位（嫩枝和老叶）的营养成分、酚类含量和抗氧化活性进行了研究。结果表明，嫩枝比老叶提供更高的能量、蛋白质、脂肪、膳食纤维、磷、钠和锌。相比之下，老叶中的总糖、维生素C、类胡萝卜素、钾、钙、镁和铁等营养成分含量更高，其酚类含量和大多数抗氧化活性也高于嫩枝。一般来说，大多数营养成分、酚类含量和抗氧化活性在不同植物来源之间没有明显趋势。7月至8月的收获期为大多数营养成分的生物合成提供了适宜的气候，而高酚类物质主要存在于3月至4月收获的样品中。根据检测技术的不同，抗氧化活性的普遍程度没有明显趋势。
