“…In a research by Deng et al [21], the results showed saponin, flavonoid and sugar in the rhizomes of P. odorata. These findings matched with a review report by Khan and Rauf [22], who concluded that homoisolflavanone, triterpenoids and steroidal saponins could be extracted from the rhizomes of P. odorata. Other than that, other chemical constituents reported by the previous study are also shown in (Table 1).…”

World Health Organization (WHO) reported that 88% of its member or 61 countries acknowledge the use of traditional and complementary medicines. Persicaria odorata is being used as traditional herbs to treat fever, nausea and promoting hair growth. Besides, it is used as an anti-inflammatory agent in Vietnam to relieve swelling and treat wounds, sores, and ulcers. This review aims to evaluate the phytochemical and pharmacological status of P. odorata. P. odorata is a plant with a high content of phenols and flavonoids. Among the essential chemical constituents in the P. odorata are methyl gallate, (+)-catechin, eupatoriochromene, n-dodecanal, polygonumins A, α-humulene and anthraquinone. P. odorata also exerts many pharmacological effects such as antioxidant, anti-inflammatory, antibacterial and anticancer effects. The commonly used part of P. odorata for extraction are leaves followed by the aerial part, rhizomes and stems. Nevertheless, more studies are needed to identify the efficacy and toxicity of P. odorata. New drugs could be developed from the active compounds of P. odorata in the future.

“…Khan and Khatoon, (2008) have reported that the local people in northern Pakistan use P. geminiflorum for the treatment of uterine tumor, menstrual abnormalities, gout, and skin diseases. Moreover, Khan and Rauf, (2015) have comprehensively described the phytochemical constituents of different species in the genus, and the associated antimibacterial, antifungal and antioxidant activities. This study has also reported that P. geminiflorum is rich in phenolics, saponins, alkaloides and phytoharmones, and therefore is a high value medicinal plant, like the most commonly explored P. vericillatum.…”

Nanomaterials are gaining tremendous potential as emerging antimicrobials in the quest to find resistance-free alternatives of chemical pesticides. In this study, stable silver nanoparticles were synthesized using the aqueous extract of medicinal plant species Polygonatum geminiflorum, and their morphological features were evaluated by transmission electron microscopy, X-ray diffraction spectroscopy and energy dispersive X-ray analysis. In vitro Antifungal activity of the synthesized silver nanoparticles (AgNPs) and P. geminiflorum extract (PE) either alone or in combination (PE-AgNPs) against Fusarium oxysporum was evaluated using disc-diffusion and well-diffusion methods. In planta assay of the same treatments against Fusarium wilt diseases of tomato was evaluated by foliar spray method. Moreover, plant extract was evaluated for the quantitative investigation of antioxidant activity, phenolics and flavonoids by spectroscopic and HPLC techniques. Phytochemical analysis indicated the presence of total phenolic and flavonoid contents as 48.32 mg ± 1.54 mg GAE/g and 57.08 mg ± 1.36 mg QE/g, respectively. The DPPH radical scavenging of leaf extract was found to be 88.23% ± 0.87%. Besides, the HPLC phenolic profile showed the presence of 15 bioactive phenolic compounds. Characterization of nanoparticles revealed the size ranging from 8 nm to 34 nm with average crystallite size of 27 nm. The FTIR analysis revealed important functional groups that were responsible for the reduction and stabilization of AgNPs. In the in vitro assays, 100 μg/ml of AgNPs and AgNPs-PE strongly inhibited Fusarium oxysporum. The same treatments tested against Fusarium sprayed on tomato plants in controlled environment exhibited nearly 100% plant survival with no observable phytotoxicity. These finding provide a simple baseline to control Fusarium wilt using silver nano bio-control agents without affecting the crop health.
