“…The results for DPPH scavenging activity of Salvia species examined in this study were inconsistent with that previously reported by Miliauskas et al [29]. Various Salvia species were shown to demonstrate remarkable scavenging activity against DPPH radicals [52][53][54]. In contrast, results from our study showed that Saponaria officinalis, A. pallida and A. glycyphyllos had the lowest DPPH scavenging activity (< 70 μmol TE/g DW).…”

Investigations have been made to study the production of phenolic compounds (total phenolics, flavonoids and phenylpropanoids) and total antioxidant capacity in 27 Macedonian traditional medicinal plants to improve its potential as a source of natural antioxidants. Antioxidant potential of plant extracts was analyzed by five different assays: cupric reducing antioxidant capacity (CUPRAC), phosphomolybdenum method (PM), reducing power (RP), 2,2-diphenyl-1-picrylhydrazyl (DPPH·) and 2,2′-azinobis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS·+) radical scavenging activity. Origanum vulgare extract consistently exhibited the highest content of phenolic compounds and the strongest antioxidant capacity based on the tests performed, and can be proposed as a promising source of natural antioxidants. Melissa officinalis and Salvia ringens were also identified as valuable sources of antioxidant compounds. A positive linear correlation between antioxidant activity and total phenolics, flavonoids and phenylpropanoids indicates that these compounds are likely to be the main antioxidants contributing to the observed activities of evaluated plants. These findings suggest that the medicinal plants studied in this paper are good sources of bioactive compounds for the food and pharmaceutical industries.

Salvia mirzayani Rech (Labiatae) (SM) is a medicinal plant that is used for diabetes in local medicine. In this research, the free radical scavenging capacity, reducing power, and inhibition of b-carotene peroxidation of an ethanol extract of SM was investigated. In addition, we examined the effect of this extract on hydrogen peroxide-induced cytotoxicity in nonimmortalized fibroblast. This extract has free radical scavenging capacity and reducing power and prevented b-carotene peroxidation. These results were confirmed by a protective effect on H 2 O 2 -induced cytotoxicity in human nonimmortalized fibroblasts. Moreover, this experimental evidence suggests that because of antioxidant activity, this extract may be useful in the treatment of human pathologies in which free radical production plays a key role.

“…There are a few studies on the antioxidant properties of S. tomentosa accomplished by DPPH method. Bozan et al (2002) stated that S. tomentosa has moderate antioxidant activity in comparison to the other Salvia species. They estimated that S. tomentosa provided almost 17% inhibition in DPPH radicals with 100 g samples, which corresponds to 1.5 mg dw mg -1 DPPH.…”

Salvia tomentosa is a common medicinal plant, and it is consumed as an herbal tea in some Mediterranean countries. It has been extensively collected from its natural habitat, and careless collection has caused the recent extinction of some plants. The present study was undertaken to cultivate S. tomentosa and compare the phenolic composition and antioxidant properties of wild and cultivated plants. Total phenolics, total flavonoids, and antioxidant activity of S. tomentosa ranged between 49.27 and 66.15 mg GAE g -1 dry weight (dw), 36.27 and 40.83 mg catechin g -1 dw, and 1.77 and 2.29 mg dw mg -1 DPPH, respectively. Total phenolic content of the cultivated samples was higher than that of wild samples. Seventeen different phenolic compounds, comprising 7 phenolic acids and 10 flavonoids, were identified and quantified in S. tomentosa. As with the many Salvia species, rosmarinic acid was quantified as the main component of S. tomentosa. It was followed by caffeic acid, morin, p-coumaric acid, and myricetin. Chlorogenic acid, p-coumaric acid, morin, kaempferol, hesperetin, and apigenin were increased through cultivation; gallic acid, caffeic acid, ferulic acid, rutin, catechin, and epicatechin were decreased. During the 6-month storage only caffeic acid changed significantly.
