For the phytochemical studies of the fruits of Kochia scoparia (L.) Schrad. (Kochiae Fructus, KF), we isolated chemical components from KF. Twenty compounds, including six alkaloids ( 1 – 6 ), nine polyphenols ( 7 – 15 ), three flavonoids ( 16 – 18 ), and two sterols ( 19 – 20 ) were isolated and identified from the ethanol extract of KF by chromatographic and spectroscopic techniques. Compounds 2 , 3 , and 5 – 16 were isolated from KF and Kochia genus for the first time. Furthermore, by discussing the taxonomic significance of these secondary metabolites, we found that Araliaceae, Compositae, Ranunculaceae, and Leguminosae might have a close evolutionary relationship. In conclusion, these results provide new insights into the chemical diversity and chemotaxonomic significance of K. scoparia in the Kochia genus and the Chenopodiaceae family.

Kochiae Fructus (KF) is a traditional Chinese medicine, which has been used to delay aging and treat inflammation, such as rubella, eczema, cutaneous pruritus, etc . In order to fully understand the traditional medicinal value of KF, we evaluated the antioxidant properties and oral safety of its ethanolic extract. Considering flavonoids and phenolics in medicinal plants generally have strong antioxidant activity, we firstly detected the total flavonoids and phenolics contents of KFEE and its fractions. Secondly, we evaluated the antioxidant activities of KFEE and its fractions. Finally, we evaluated the oral safety of KFEE by the acute and 28-day subacute toxicities. The n-butanol fraction (ENBF) possessed the highest phenolics and flavonoids with values of 77.30 ± 3.17 mg gallic acid equivalents/g and 228.81 ± 7.56 mg rutin equivalents/g, respectively. The results of antioxidant tests showed that ENBF possessed potent antioxidant ability. Among them, the high antioxidation capacity observed in ENBF could be attributed to its rich content of flavonoids and phenolics. The results of toxicological studies showed that the LD 50 value of KFEE was 6000 mg/kg BW, and the no observed adverse effect level (NOAEL) of KFEE was 600 mg/kg BW. According to the standards of the American Academy of Sciences for the classification of toxic substances, KFEE can be classified as practically non-toxic substance, which provided valuable evidence for the oral safety of KF as a natural aging delay medicine.

Kochiae Fructus (KF) was listed as ‘top grade’ medicinal material by the ‘Shennong's Herbal Classic of Materia Medica’ and has been used in traditional Chinese medicine to delay aging and treat inflammation, such as rubella, eczema, cutaneous pruritus, etc. Our research focused on the antioxidant capability of water decoction and fractions from KF based on 2,2-iphenyl-1-picrylhydrazyl (DPPH) free radical and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) cation radical scavenging assay, the ferric reducing antioxidant power assay, and inhibitory effects on DNA and protein oxidative damage. The results of total phenolics and flavonoids contents showed that ethyl acetate fraction (EAF) possessed the highest phenolics and flavonoids with values of 112.90 ± 9.58 mg gallic acid equivalents/g and 329.60 ± 20.93 mg rutin equivalents/g, respectively. At the same time, the results of antioxidant capacities showed that EAF possessed best antioxidant abilities. In addition, in this work, we evaluated the oral safety of the water decoction of KF (KFWD) via the 14-day acute and 28-day subacute toxicity tests. The results of in vivo toxicity assessment showed that KFWD did not cause significant changes in the general clinical symptoms, hematology and biochemical parameters, organ weights, or histopathological appearances in mice or rats. In summary, the reason why KF has the traditional effect on delaying aging may be related to the fact that its rich in flavonoids and phenolics. Simultaneously, no toxicity was detected after acute or subacute treatment of KFWD, providing valuable evidence for the traditional safe use of KF.
