摘要

积雪草(Centella Asiatica或Pegagan)被归类为未经驯化的野生植物之一。这种植物在传统和现代医学应用中的过度使用威胁着它的数量和可持续性。因此,为了保护该植物,满足农业医药工业对该植物的高要求,迫切需要在商业大田条件下对Pegagan的生长和生物活性成分进行研究。本研究的目的是在野外条件下检测Pegagan的生物活性成分(特别是在叶子和根中),包括积雪草苷、马白果苷和积雪草酸。Pegagan在种植几周后收获。称重叶片和根的湿重和干重,随后用薄层色谱(TLC)方法测定它们的centelloside化合物。结果表明:根中积雪草苷含量(1.25%)高于叶中积雪草苷含量(0.88%);栀子苷在根中的含量为2.23%,在叶中的含量为2.11%。相反,叶片中亚细亚酸化合物的含量比根(0.60%)高1.10%。这可能是由于长时间的田间栽培,使植物有足够的时间将亚洲酸转化为积雪草苷,并在较晚的发育生长中产生积雪草苷。此外,这些发现有助于确定商业种植Pegagan的最佳收获时间,以获得最高数量的某些centello苷化合物。

Analyses of Bioactive Compounds of Pegagan (Centella Asiatica (L.) Urb) from Samosir – Indonesia Accession
Centella Asiatica or Pegagan is classified as one of the wild plants that has not been domesticated. The excessive usage of this plant in traditional and modern medicinal applications threatens its population and sustainability. Thus, to preserve the plant and supply the high request of this plant in agromedicinal industry, studies concerned with the growth and bioactive compounds of Pegagan cultivated under commercial field conditions are urgently needed. This study purposed to examine the bioactive components of Pegagan (especially in leaves and roots) under field conditions, including asiaticoside, madeccasoside, and Asiatic acid. The Pegagan was harvested weeks after planting (WAP). The wet and dry weights of the leaves and roots were weighted and subsequently measured for their centelloside compounds by Thin-Layer Chromatography (TLC) procedure. The results revealed that the resulting asiaticoside content in the roots (1.25%) was higher than in the leaves (0.88%). The same results were achieved for the madecassoside content where the madecasosside content in the roots was 2.23%, while the content in the leaves was 2.11%. However, contrarily, the Asiatic acid compound in the leaves was 1.10% higher than the content in the roots (0.60%). It might be attributed to a longer period of field cultivation of Pegagan that delivered adequate time for the plant to alter Asiatic acid to asiaticoside and madecasosside at a later developmental growth. Moreover, these discoveries are advantageous in defining the most proper harvest time for commercial field cultivation of Pegagan to yield the highest amount of certain centelloside compounds.
