Six morphotypes of Centella asiatica designated G(1), G(2), G(3), G(7), G(8) and G(12) were analyzed for carotenoid content, proximate components and selected dietary minerals. Potassium was found to be the major element present in C. asiatica and the content in G(1) and G(3) (6,165.0 ± 125.8 mg/100 g dry weight) was significantly (P < 0.05) higher than all other morphotypes. C. asiatica is more popular for its higher contents of iron and calcium. However, no significant (P>0.05) differences in calcium content among the morphotypes were observed. The imported variety G(7) had significantly higher (P < 0.05) mean content of iron (74.3 ± 34.1 mg/100 g dry weight). The morphotypes G(8) and G(12) contained significantly higher (P < 0.05) content of β-carotene (77.2 ± 5.1 μg/g fresh weight) and lutein (133.5 ± 10.1 μg/g, fresh weight) respectively. Lutein and β-carotene levels of these two types were also significantly higher (P < 0.05) than those in the other varieties. The study did not provide any evidence to believe that a given morphotype is superior to another in its overall nutritional value.
六种形态的积雪草（Centella asiatica）被指定为 G(1)、G(2)、G(3)、G(7)、G(8) 和 G(12)，分析了它们的类胡萝卜素含量、近似成分和选定的膳食矿物质。钾是积雪草中含量最多的元素，G(1) 和 G(3) 中的含量（6,165.0±125.8mg/100g 干重）明显（P<0.05）高于其他所有形态类型。积雪草因其铁和钙含量较高而更为流行。然而，形态类型之间的钙含量没有显著差异（P>0.05）。进口品种 G(7) 的铁含量（74.3±34.1mg/100g 干重）明显更高（P<0.05）。形态类型 G(8) 和 G(12) 分别含有更高含量的β-胡萝卜素（77.2±5.1μg/g 鲜重）和叶黄素（133.5±10.1μg/g，鲜重）。这两种类型的叶黄素和β-胡萝卜素含量也明显高于其他品种。研究没有提供任何证据表明，在整体营养价值方面，给定的形态类型优于另一种。
