Antioxidant activity of microwave-assisted extract of longan (Dimocarpus Longan Lour.) peel

Similarities Between Species of Ocimum and Mentha on the Basis of Phytochemical and Dna Quantification Study

“…In Croton bonplandianus extract alkolids and flavonoids were found absent whereas glycosides, saponins, tannins, proteins, free amino acid, carbohydrates and vitamin C were found present (Table 1). Similar phytochemicals were reported during characterization of medicinal plants 16 . Similar results were reported by various studies that ethanolic fraction possesses highest amount of phenolic and poly phenolic compounds 17,18 DNA extraction and DNA quantification DNA was isolated from three species of O. sanctum and M. spicata species by using the protocol of Richards (1997), with some modifications 11 and then it was run on 0.8% agarose in 1× TAE buffer to check the quality and quantity of isolated DNA.…”

Antioxidant activities of fractions from longan pericarps

“…There are some reports pointed that reducing power of plant extracts was associated with their antioxidant activity (Pan et al, 2008). Figure 4 showed the dose-response curves for reducing power of the extracts and fractions from longan fruit pericarp.…”

“…DPPH radical scavenging assay is a widely used method to estimate free radical scavenging activities of antioxidants now for its advantage of economical and ease (Pan et al, 2008). A dose-response curve of DPPH radicals scavenging activities of the fractions from longan fruit pericarp was presented in Figure 1.…”

“…The EC 50 values of LPEF and LPDF were 0.253 and 0.260 mg/mL, while LPBF and LPCE were 0.407 and 0.498 mg/mL (Table 1). Yingming Pan et al (2008) revealed the reducing power of Soxhlet extract of longan peel was lower (the absorbance at 700 nm was 1.439 at 1.0 mg/mL) (Sudjaroen et al, 2012).…”

Assessment of effect of hydroalcoholic and decoction methods on extraction of antioxidants from selected Indian medicinal plants

“…The DPPH radical scavenging activity of extract has been attributed to the ability of these extracts in pairing with the old electron of DPPH radical [51] . The antioxidants are able to reduce the stable DPPH radical to yellow-colored and the antioxidant power is indicated by the degree of discoloration which could be determined by measuring of a decrease in the absorbance at 517 nm [52] . Because of the ease and convenience of this reaction, it has now widespread use in the free radical scavenging activity assessment [40] .…”
