Question: Annona muricata Linn. contains a group of bioactive long chain fatty acid derivatives called Annonaceous acetogenins, which have shown selective cytotoxicity against several cancer cell lines and other abnormal cells by a known mechanism. The current study analyzed the phytochemical and antioxidant properties of the fruit skin ethanolic extract of Annona muricata (ESA) and its effect ...

Objective:The purpose of this study was to investigate the effects of piroxicam co-administration with ethanolic stem-bark extract of Khaya senegalensis on biomarkers of oxidative stress and gastro-toxicity in Wistar rats. Materials and Methods: Thirty healthy male and female Albino Wistar rats (190-220 g) were grouped into six (n = 5) with designated treatments including: Normal saline, piroxi...

The free radical scavenging potential of the leaves of A. squamosa was studied by using different antioxidant models of screening. The ethanolic extract at 1000 microg/ml showed maximum scavenging of the radical cation, 2,2-azinobis- (3-ethylbenzothiazoline-6-sulphonate) (ABTS) observed upto 99.07% followed by the scavenging of the stable radical 1,1-diphenyl, 2-picryl hydrazyl (DPPH) (89.77 %)...

PREMISE OF THE STUDY A variety of mechanisms to prevent inbreeding have arisen in different angiosperm taxa during plant evolution. In early-divergent angiosperms, a widespread system is dichogamy, in which female and male structures do not mature simultaneously, thus encouraging cross pollination. While this system is common in early-divergent angiosperms, it is less widespread in more recentl...

Development of alternative methods for pest management is needed with the increased concern for adverse effects of pesticides for human health and the environment. The main goal of our study was to test the oil from seeds of sugar apple (Annona squamosa), an edible tropical fruit for pest control. The oil pressed out of seeds was as effective in controlling the silverleaf whitefly, Bemisia arge...

In the present study, the chemical investigation of the leaves of Annona reticulata has resulted in the identification of nine compounds, including annonaretin A, a new triterpenoid. The purified compounds were subjected to the examination of their effects on NO inhibition in LPS-activated mouse peritoneal macrophages and most of them exhibited significant NO inhibition, with IC₅₀ values in the...

The aim of this study was to evaluate the effect of pre-treatments on overcoming dormancy of A. coriacea seeds. Seeds were processed and stored in polyethylene bags at temperatures of at -18°C (42% RH), 5°C (34% RH), 15°C (60% RH) and 25°C (34% RH), during 0, 30, 60, 90, 120 and 150 days. After storage, seeds were immersed in 350 mg.L-1 gibberellic acid for 144 hours. Sowing was carried out in ...

A typical Brazilian plant, araticum (Annona crassiflora Mart.), is widely used in humans as therapeutic medicine to treat several diseases such as diarrhea, rheumatism and syphilis. It contains acetogenins which present cytotoxic, antitumogenic, and antiparasitic properties. In this study, mutagenic, antimutagenic and cytotoxic effects of araticum leaves ethanolic extract were evaluated by micr...
