Abstract

Alocasia longiloba Miq. (Araceae) is a Southeast Asian understory plant with limited anatomical and phytochemical studies. This work provides the first integrative characterization of its root, rhizome, petiole and lamina. Anatomical examination revealed a polyarch stele in roots, abundant calcium oxalate crystals in the rhizome and irregularly distributed vascular bundles in leaf tissues. Qualitative phytochemical screening of ethanolic extracts confirmed the presence of triterpenoids, flavonoids, phenolics, alkaloids, saponins, steroids and coumarins. Quantitative analysis showed higher total triterpenoid and polyphenol contents in the roots, while flavonoid content was greater in the rhizome. These findings offer foundational anatomical and chemical data, contributing to future taxonomic, ecological and pharmacognostic studies of A. longiloba. The species’ metabolite-rich tissues highlight its potential as a sustainable resource for natural product development and support ongoing biodiversity and health-related research efforts.

综合形态解剖和植物化学表征的药用和环境可持续应用的龙葵

龙葵。天南星科是东南亚的一种林下植物，在解剖学和植物化学方面的研究有限。这项工作提供了其根，根茎，叶柄和叶片的第一个综合表征。解剖检查显示根有多拱形柱，根茎中有丰富的草酸钙晶体，叶组织中有不规则分布的维管束。定性植物化学筛选乙醇提取物证实存在三萜、黄酮类、酚类、生物碱、皂苷、类固醇和香豆素。定量分析表明，根中总三萜和多酚含量较高，而根茎中总黄酮含量较高。这些发现提供了基础的解剖学和化学数据，有助于进一步开展龙骨草的分类学、生态学和生药学研究。该物种富含代谢物的组织突出了其作为天然产品开发的可持续资源的潜力，并支持正在进行的生物多样性和健康相关研究工作。
