  • Annona muricata, generally known as soursop, graviola, or sirsak, is native to the warmest tropical areas of North and South America and is now widely distributed throughout tropical and subtropical parts of the world, including India and Nigeria. This study tested the contents of polyphenolic compounds, flavonoids, and minerals, as well as the antioxidative effects of DPPH radical-scavenging activity, Fe/Cu-reducing power, linoleic-acid peroxidation using thiobarbituric-acid (TBA) methods and peroxidation of rat-hepatocyte microsomes, and ${\beta}$-carotene bleaching assay. These were tested with in-vitro experimental models using water, ethanol, and methanol extracts of the Annona muricata leaf (AMl). Water extracts of AMl showed the highest extraction yield (1.76%). The total polyphenol-compound concentration was the highest in the methanol extract of AMl. However, the flavonoids concentration was the highest in the ethanol extracts of AMl. AMlMl major minerals were Ca, K, and Mg. In DPPH radical-scavenging activity, the contents exhibited a strong scavenging effect on the ethanol and methanol extracts of AMl. Additionally, the Fe/Cu-reducing power was strong in ethanol and methanol extracts of AMl. $Fe^{2+}$/ascorbate-induced linoleic-acid peroxidation using TBA methods and auto-oxidation of rat-hepatic microsomes showed strong antioxidative activities in ethanol extracts of AMl. ${\beta}$-Carotene bleaching was also highest in the ethanol extracts of AMl. These results may provide the basic data to understand the chemical characteristics and antioxidative effects of Annona muricata leaf extract for the development of functional foods.

  • The objective of this study was to evaluate the anti-melanogenic effects of crude polysaccharide fractions from Annona muricata L. (ALP) in 3-isobutyl-1-methylxanthine (IBMX) stimulating hormone-induced mouse B16F10 melanoma cells. The inhibitory effect of ALP on tyrosinase activity was approximately $33.88{\pm}0.79%$ at 5 mg/mL. Additionally, the B16F10 cellular tyrosinase and melanin synthesis inhibition activities by ALP were $54.21{\pm}4.76$ and $56.74{\pm}6.97%$ at $250{\mu}g/mL$, respectively. Similarly, whitening-related protein tyrosinase, tyrosinase-related protein 1 (TRP-1) and TRP-2, and microphthalmia-associated transcription factor (MITF) were reduced by ALP treatment. These results indicated that ALP could be used as a functional cosmetic ingredient after confirming its whitening activity related to melanin content.

  • Annona muricata L (Annonaceae), commonly known as soursop has a long, rich history in herbal medicine with a lengthy recorded indigenous use. It had also been found to be a promising new anti-tumor agent in numerous in vitro studies. The present investigation concerns chemopreventive effects in a two-stage model of skin papillomagenesis. Chemopreventive effects of an ethanolic extract of A. muricata leaves (AMLE) was evaluated in 6-7 week old ICR mice given a single topical application of 7,12-dimethylbenza(${\alpha}$)anthracene (DMBA 100ug/100ul acetone) and promotion by repeated application of croton oil (1% in acetone/twice a week) for 10 weeks. Morphological tumor incidence, burden and volume were measured, with histological evaluation of skin tissue. Topical application of AMLE at 30, 100 and 300mg/kg significantly reduced DMBA/croton oil induced mice skin papillomagenesis in (i) peri-initiation protocol (AMLE from 7 days prior to 7 days after DMBA), (ii) promotion protocol (AMLE 30 minutes after croton oil), or (iii) both peri-initiation and promotion protocol (AMLE 7 days prior to 7 day after DMBA and AMLE 30 minutes after croton oil throughout the experimental period), in a dose dependent manner (p<0.05) as compared to carcinogen-treated control. Furthermore, the average latent period was significantly increased in theAMLE-treated group. Interestingly, At 100 and 300 mg/kg, AMLE completely inhibited the tumor development in all stages. Histopathological study revealed that tumor growth from the AMLE-treated groups showed only slight hyperplasia and absence of keratin pearls and rete ridges. The results, thus suggest that the A.muricata leaves extract was able to suppress tumor initiation as well as tumor promotion even at lower dosage.

  • In this study, graviola leaf extracts (GLE) was investigated for the effect of antioxidant, antibacterial, whitening, anti-wrinkle. The antioxidant effect of GLE was measured by an electron donating ability assay. As a result, GLE increased the electron donating ability in a concentration-dependent manner. The antibacterial effect of GLE was found to show the higher antibacterial effect in Methicillin-resistant Staphylococcus aureus CCARM3115 compared with that of ampicillin by a paper disc method. The whitening effect of GLE was also measured by tyrosinase inhibition assay, and it was found that the tyrosinase activity of GLE decreased as the concentration increased. The inhibition activity of tyrosinase involved in hydroxylation reaction which is related to converting L-tyrosine to (DOPA) was higher than that of arbutin's at the concentration ranging from 125 to $250{\mu}g/mL$. In addition, GLE reduced melanin contents of B16-F10 melanoma cells in a dose-dependant manner and decreased to about 76.7% at a concentration of $100{\mu}g/mL$ Regarding wrinkling formation of GLE, an elastase inhibition assay was performed. As a result, GLE and ursolic acid were 10.5% and 56.5%, respectively under the identical concentration. These results suggest that GLE has significant antioxidant and whitening activities, and also may be potentially used as a therapeutic agent for hyperpigmentation treatment as an ingredient of whitening cosmetics.

  • This study compared the immuno-modulatory effects of ethanol extracts (A. muricata L. ethanol extracts, ALE) and crude polysaccharide fraction (A. muricata L. crude polysaccharide fraction, ALP) from Annona muricata L. in macrophages. Immuno-modulatory activity was determined by assessing cell viability, nitric oxide (NO) production, inducible NO synthase (iNOS) expression and cytokine production in RAW 264.7 a macrophage cell line. Both ALE and ALP treatment did not affect cytotoxicity, and ALP treatment significantly increased NO production. Additionally, cytokine production [tumor necrosis factor ($TNF-{\alpha}$; $2909.04{\pm}4.1pg/mL$), interleukin (IL)-6; $662.84{\pm}5.3pg/mL$, and $IL-1{\beta}$; $852.37{\pm}2.2pg/mL$), was highly increased in the ALP ($250{\mu}g/mL$) treated group compared to the ALE ($250{\mu}g/mL$) treated group ($TNF-{\alpha}$; $1564.50{\pm}6.1pg/mL$, IL-6; $517.24{\pm}4.1pg/mL$ and $IL-1{\beta}$; $237.23{\pm}1.8pg/mL$). Moreover, ALP treatment considerably increased the expression of mitogen-activated protein kinase (MAPKs) and nuclear $factor-{\kappa}B$ ($NF-{\kappa}B$) in the macrophages. Therefore, ALP can induce macrophage activation through MAPK and $NF-{\kappa}B$ signaling and this can be a potential candidate for development of nutraceuticals.

  • In this study, the antioxidative effects and component analysis of 50% ethanol extract, ethyl acetate fraction and aglycone fraction obtained from Annona muricata leaf were investigated. Free radical scavenging activities were performed by 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay, total antioxidant capacities were estimated using luminol-dependent chemiluminescence assay and $^1O_2$ quenching effects were estimated. Free radical scavenging activities ($FSC_{50}$) of 50% ethanol extract, ethyl acetate fraction and aglycone fraction were 45.6, 29.8 and $18.0{\mu}g/mL$, and total antioxidant capacities ($OSC_{50}$) were 4.4, 1.1 and $2.8{\mu}g/mL$, respectively. As a result of $^1O_2$ quenching experiment, ethyl acetate and aglycone fraction showed similar activities to L-ascorbic acid used as a comparative control. The cellular protective effects of 50% ethanol extract on the $^1O_2-induced$ cellular damage of human erythrocytes were exhibited at concentration-dependent ($5-50{\mu}g/mL$). TLC and HPLC were used to analyse components in the ethyl acetate fraction and aglycone fraction of Annona muricata leaf. In ethyl acetate fraction, rutin (quercetin-3-O-rutinoside), kaempferol-3-O-neohesperidoside, nicotiflorin (kaempferol-3-O-rutinoside), p-coumaric acid were identified. In aglycone fraction, kaempferol was identified. These results suggest that the extracts of Annona muricata leaf have the applicability as antioxidant cosmeceutical ingredients.

  • Natural products have been the target for cancer therapy for several years but there is still a dearth of information on potent compounds that may protect normal cells and selectively destroy cancerous cells. The present study was aimed to evaluate the cytotoxic potential of n-butanolic leaf extract of $Annona$ $muricata$ L. on WRL-68 (normal human hepatic cells), MDA-MB-435S (human breast carcinoma cells) and HaCaT (human immortalized keratinocyte cells) lines by XTT assay. Prior to cytotoxicity testing, the extract was subjected to phytochemical screening for detecting the presence of compounds with therapeutic potential. Their relative antioxidant properties were evaluated using the reducing power and $DPPH^*$radical scavenging assay. Since most of the observed chemo-preventive potential invariably correlated with the amount of total phenolics present in the extract, their levels were quantified and identified by HPLC analysis. Correlation studies indicated a strong and significant (P<0.05) positive correlation of phenolic compounds with free radical scavenging potential. The results revealed that the extract was moderately cytotoxic to normal cells with a mean IC50 value of 52.4 ${\mu}g$ when compared with those obtained for cancerous cells (IC50 values of 29.2 ${\mu}g$ for MDA-MB-435S and 30.1 ${\mu}g$ for HaCaT respectively). The study confirms the presence of therapeutically active antineoplastic compounds in the n-butanolic leaf extract of $Annona$ $muricata$. Isolation of the active metabolites from the extract is in prospect.

  • This study was focused on the anti-inflammatory activities of Annona muricata leaf ethanol extracts (AME). Inflammation of macrophages was induced by lipopolysaccharide (LPS) treatment, and various inflammation-mediated factors [cytokines and nitric oxide (NO)] were measured. AME treatment significantly reduced LPS-induced NO, cytokine levels [interleukin (IL)-6, tumor necrosis $factor-{\alpha}$ and $IL-1{\beta}$], and expression of inducible NO synthase and cyclooxygenase-2 in a dose-dependent manner. Mechanical studies showed that AME treatment inhibited activation of mitogen-activated protein kinase and nuclear factor $(NF)-{\kappa}B$ in macrophages treated with LPS. From these results, AME treatment strongly inhibits LPS-induced inflammation through inhibition of $NF-{\kappa}B$ activation, suggesting AME could be a potential candidate for treatment of inflammatory disease as a nutraceutical drug.
