“…Preliminary phytochemical analysis indicates the presence of steroids, triterpenes, essential oils, flavonoids, and saponins in EEH, which is in accord with the results previously described by Adams et al (1989), Fischer et al (1994, and Martins et al (2008). When considering the most studied plant of the genus, Hydrocotyle asiatica L., Wijeera et al (2006) attributed the pharmacological actions of H. asiatica to the triterpene rich fractions and described the anxiolytic-like effect of the triterpene asiaticoside in rats, while Chen et al (2006) showed the anxiolytic-like effects of this compound in mice.…”

Abstract:The plant Hydrocotyle umbellata L., Araliaceae (water pennywort), is widely used in Brazilian folk medicine to reduce anxiety. This work investigates the anxiolytic-like effects of the ethanol extract from H. umbellata subterraneous parts as well as the extract's other putative central nervous system effects that could justify its common use. Oral dosing of the extract (0.3 and 1 g/kg) clearly showed an anxiolytic-like profile in the elevated plus maze test where it increased the percentage of entries into and the time spent in the open arms of the maze. In the marble-burying test, the extract induced anxiolyticlike effects only at a dose of 1 g/kg, which also causes mild sedative properties in other models. The sedated state was characterized by a slight reduction in spontaneous exploratory activity during the open field test and a potentiating of pentobarbital-induced hypnosis. No signs of motor impairment were detected in the rota rod or chimney tests. The extract did not show antidepressant properties in mice as assessed by the forced swimming test. These results support the use of H. umbellata in Brazilian folk medicine as an anxiolytic and contribute to the scientific knowledge of this possible phytotherapeutic resource.

“…Furthermore, C. asiatica is reported to contain several flavonoid derivatives such as quercetin, kaempferol, patuletin, rutin, apigenin, castilliferol, castillicetin, and myricetin 35 . According to previous phytochemical studies, H. umbellata leaves also contain flavonoids, essential oils, saponins, and tannins 36–38 . The study revealed two new ergostane glycosides isolated from the leaves of H. umbellata indicating a possible correlation with the biological activities 39 .…”

IntroductionCentella is an important genus in the Apiaceae family. It includes Centella asiatica, which has significant edible and medicinal values. However, this species is easily confused due to its similar morphological traits to Hydrocotyle umbellata, hindering its utilization in the consumer and pharmacological industries.ObjectiveThe study aims to differentiate these two closely related plant species using reliable methods of confirming the authenticity of natural herbal medicines.MethodsOur work mainly focuses on the basic morphological characteristics, chemical markers, genetic fingerprints, and their biological responses.ResultsThe plants can be clearly differentiated using their leaf shapes, stipules, petioles, inflorescences, and fruit structures. Although the phytochemical compositions of the C. asiatica extract were similar to that of H. umbellata which included flavonoids, tannins, and saponins important to the plant's ability to reduce inflammation and promote healing of wounds, the H. umbellata extract showed significantly higher toxicity than that of C. asiatica. High‐performance liquid chromatography analysis was used to identify chemical fingerprints. The result revealed that C. asiatica had major triterpene glycoside constituents including asiaticoside, asiatic acid, madecassoside, and madecassic acid, which have a wide range of medicinal values. In contrast, triterpenoid saponins were not identified in H. umbellata. Furthermore, using SCoT1–6 primers was possible to effectively and sufficiently created a dendrogram which successfully identified the closeness of the plants and confirmed the differences between the two plant species.ConclusionTherefore, differentiation can be achieved through the combination of morphometrics, molecular bioactivity, and chemical analysis.
