The present study was designed to evaluate and compare the phenolic (total phenols and flavonoid) contents and antioxidant activity of aqueous extract of Momordica foetida (AEMF) and ethanolic extract of Momordica foetida (EEMF) extract of Momordica foetida leaves; a popular medicinal plant used for traditional medicine preparations. The antioxidant activity of both extracts was assessed using ...

BACKGROUND Launaea procumbens (LP) has been used as a food supplement in Pakistan. In this study methanolic crude extract (LPME) of the whole plant and its different fractions; n-hexane (LPHE); ethyl acetate (LPEE) and chloroform (LPCE) were studied for the determination of total flavonoid and phenolics contents along with multifaceted in vitro scavenging assays. RESULTS Considerable amount o...

Many plants are used ethnomedicinally for the treatment of disease and restoration health. One these medicinal is Tithonia diversifolia . This study aims to determine phenolic flavonoid contents antioxidant activity using DPPH method from leaves T. Phenolic identification was carried out with FeCl 3 reagent; blackish green color formed indicates presence compounds. Identification a reagent betw...

long exposure of uv radiation increases risk of skin diseases such as cancer and photoallergic reactions. uv-b (280-320 nm) radiation is mainly responsible for inducing skin problems. skin protection is a suitable method in the fight against ultraviolet radiation induced damage. various synthetic agents have been used as photo protective but because of their potential toxicity in humans, they h...

Background: In Nigeria, the leaves of Manihot esculenta (Crantz) are eaten as vegetables. The leaves are rich in phytochemicals, valuable and natural sources of antioxidants, and are highly useful for human health and disease prevention. This study was aimed to evaluate the in vitro inhibitory effects of two extracts derived from the plant leaves on α-glucosidase and α-amylase. The total flavon...

Antioxidant activity of Peucedanum pastinacifolium Boiss. & Hausskn aerial part hydroalcoholic extract (HAE) and polyphenolic extract (PPE) as well as their total phenolic and flavonoid contents were studied. Phenolic and flavonoid contents were respectively estimated as gallic acid and quercetin equivalents. The in vitro antioxidant activity of two extracts of P. pastinacifolium were evaluated...

Objective: Prunus domestica is known for its nutritional values and therapeutic properties. It contains rich amount of natural phenolic phytochemicals such as phenolic acids, flavonoids and anthocyanin. Previous reports suggest that prune extract and juice inhibit peroxidation process. As no detailed antioxidant property, particularly on the whole fruit was studied, in this investigation, we no...

Lythrum salicaria L. (Lythraceae) known as purple loosestrife used for its beneficial health effects against as many human diseases such as diarrhea, hemorrhoid, eczema internally and/ or externally. The effects of the different extracting methods on the total phenolic (TP) and total flavonoid (TF) contents of Lythrum salicaria L. extracts were investigated. Dried leaf and flower of L. salicari...

Two underutilized indigenous fruits of Borneo, Liposu (Baccaurea lanceolata) and Tampoi (Baccaurea macrocarpa) were investigated for their total phenolic (TPC), flavonoid (TFC), anthocyanin (TAC) and carotenoid (TCC) contents as well as antioxidant properties in vitro. The fruits were separated into three different parts (i.e., pericarp, flesh and seed) and extracted using 80% methanol. Antioxi...

Fruits are a rich source of antioxidants and traditional Chinese fruits have been studied for their chemopreventive and chemotherapeutic properties against cancers and other diseases. The total phenol and flavonoid contents of eleven Chinese fruits extracts were determined. Total phenolic and flavonoid contents were estimated by both the Folin-Ciocalteau and aluminium chloride methods. The anti...
