Partial Purification, Identification, and Quantitation of Antioxidants from Wild Rice (Zizania latifolia)

To provide further insights into the potential health-promoting antioxidants from wild rice (Zizania latifolia), which is an abundant but underutilized whole grain resource in East Asia, a partial purification based on D101 macroporous resin was carried out for the purification and enrichment of the antioxidants from the bioactive ethanol extracts of wild rice. On that basis, 34 phenolic compounds in the antioxidant fractions were identified by a high-performance liquid chromatography-linear ion trap quadrupole-Orbitrap-mass spectrometry (HPLC-LTQ-Orbitrap-MSn). The results suggested that phenolic acids could be enriched in the 10% ethanol-eluted fraction whereas flavonoids (including procyanidins and flavonoid glycosides) could be enriched in 20–30% ethanol-eluted fractions. A quantitative analysis determined by the multiple reaction monitoring mode of the ultra-performance liquid chromatography-triple quadrupole-tandem mass spectrometry (UPLC-QqQ-MS/MS) revealed a high content of procyanidins in wild rice. Compared with phenolic acids, flavonoids may contribute more to the potent antioxidant activity of wild rice. This is the first study on the antioxidants from wild rice Z. latifolia. These findings provide novel information on the functional components of wild rice, and will be of value to further research and development on Z. latifolia.

This study assessed the anthelmintic activity of plant-derived compounds against gastrointestinal nematodes of goats using the egg hatch and larval motility assays. The compounds tested were saponins (digitonin and aescin) and their respective sapogenins (aglycones), hecogenin acetate and flavonoids (catechin, hesperidin, isocordoin and a mixture of isocordoin and cordoin). Additionally, cytotoxicity of active substances was analysed on Vero cell through 3-4,5-dimethylthiazol-2-yl,2,5diphenyltetrazolium bromide (MTT) and propidium iodide (PI) tests. Significant reduction on the egg hatching (P 90%). Nevertheless, higher cytotoxicity was observed in the MTT assay, with IC50 of 0.20 mg mL-1 (aescin) and 0.0074 mg mL-1 (digitonin). Aescin and digitonin have a pronounced in vitro anthelmintic effect and the glycone portion of these saponins plays an important role in this activity.

“…The author also concluded that the tannins are not the only metabolites secondary involved in the antiparasitic effects of the extract. In other study, Santos et al (2017) evaluated extracts and fractions from Digitaria insularis leaves against eggs of H. contortus and obtained IC 50 values ranging from 0.27 mg mL -1 to 0.96 mg mL -1 , however the nematocidal activity of this plant was attributed to the presence of flavones.…”

Gastrointestinal nematodes can affect sheep productivity via severe weight loss, anemia and death. Infection control is generally performed with synthetic anthelmintic compounds; however, indiscriminate use of these drugs can stimulate the emergence of resistant nematodes. Thus, alternatives to the use of synthetic anthelmintic compounds have been proposed, such as the inclusion of medicinal plants in animal feed. The objective of this study was evaluate the anthelmintic activity of the leaves of the medicinal plant Psidium cattleianum Sabine (Araçá) through its hydroalcoholic extract, and using in vitro assays with the eggs and larvae of gastrointestinal nematodes obtained from naturally infected donor sheep. The extract exhibited good in vitro ovicidal and larvicidal activity, with IC 50 values of 0.55 mg mL-1 for egg hatching inhibition, 0.20 mg mL-1 for larval development inhibition and an efficiency greater than 80% in the inhibition of larval migration at all concentrations evaluated (IC 50 < 0.19 mg/mL). Phytochemical analysis detected higher concentrations of saponins, flavonoids, cardiac glycosides, anthraquinones and tannins in the extract. Our results demonstrated that the Psidium cattleianum Sabine's leaves exhibit in vitro anthelmintic activity, which suggests that in addition to its other medicinal properties, this plant can help control gastrointestinal nematodes in sheep. Future in vivo assays should be performed to confirm antiparasitic efficacy.
