Background: Polycystic ovary syndrome (PCOS) is a global health concern for women in reproductive age women. Numerous studies have been reported an association between chronic inflammation and alteration of cytokine in women with PCOS. Syzygium polyanthum (S. polyanthum) contains antioxidants and has antiinflammation activity. Objectives: This study aims to measure the alteration of IL-6, BMP-15, and GDF-9 in rat PCOS model after treated with S. polyanthum leaves extract. Materials and Methods: The female Wistar rats were divided into five groups (n = 5), K0 (normal control), K1 (PCOS group), and three treatment groups which received three different doses of S. polyanthum leaves extract. The treatment group consisted of PCOS rat models with S. polyanthum leaves extract supplementation of 150 mg/KgBW (P1), 300 mg/KgBW (P2), and 450 mg/KgBW (P3). Results: IL-6 expression was highest in K1 (4,690 {\textpm} 0.099) and lowest in the P3 treatment, namely (2,370 {\textpm} 0.105). The expression of BMP-15 and GDF-9 was lowest at K1 (2.554 {\textpm} 0.04; 4.502 {\textpm} 0.050) and highest at P3, namely (2.265 {\textpm} 0.072; 4.736{\textpm}0.074). Conclusion: S. polyanthum leaves extract was significantly effective in decreasing IL-6 expressions, as well as a significant increase in BMP-15 and GDF-9 expressions in the PCOS rat model.

Background: Polycystic ovary syndrome (PCOS) is an endocrine and reproductive disorder affecting 5\% to 13\% of women of reproductive age. Approximately 80\% of women with PCOS underwent infertility cases. Many studies have shown an association between PCOS and low-grade inflammation. Syzygium polyanthum (S. polyanthum) contains antioxidants and has antiinflammation activity. Objectives: This study aims to investigate the effectiveness of S. polyanthum leaf on glutathione, tumour necrosis factoralpha (TNF-α), sPDL1, and DeGraff follicle expression in PCOS rat models. Materials and Methods: The female Wistar rats were divided into five groups (n = 5), K0 (normal control), K1 (PCOS group), and three treatment groups which received three different doses of S. polyanthum extract. The treatment group consisted of PCOS rat models with S. polyanthum extract supplementation of 150 mg/KgBW (P1), 300 mg/KgBW (P2), and 450 mg/KgBW (P3). Results: S. polyanthum leaf extract significantly decreased TNF-α expression in the treatment group. The highest TNF-α, GSH, and sPDL1 concentration was found in the P3 group (3.83{\textpm}0.123, 273.12{\textpm}12.4 ng/ml, and 3.25 ng/ml, respectively). Moreover, the number of follicles was statistically significant in the P1, P2, and P3 groups (2.0, 3.0, and 3.50, respectively). The number of follicles in the P1, P2, and P3 groups was higher than in the positive control; however, it was lower in the negative control (K0) (p\<0.05). Conclusion: S. polyanthum extract was significantly effective in decreasing TNF-α expression, as well as a significant increase GSH, sPDL1 and DeGraff foliclle count in PCOS rat model.

Introduction: Syzygium polyanthum leaves extract that contains gallic acid as the major phenolic compound has shown significant antihypertensive effect, however the amount of gallic acid was inversely-related with magnitude of this effect. This study aimed to conduct bioassay-guided fractionation of S. polyanthum leaves with gallic acid as a reference compound, and to screen for other possible compounds responsible for the antihypertensive effect. Methods: S. polyanthum leaves were extracted using n-hexane, ethyl acetate, methanol, and water. The most active crude extract was fractionated using column chromatography and analyzed for total phenolic content (TPC) (n=3). Crude extracts and the derived fractions were intravenously administered into pentobarbital-anaesthetized Spontaneously Hypertensive rats (n=5) for recording of blood pressure parameters. Liquid Chromatography-Quadruple Time-Off-Flight/Mass Spectrometry was used for determination of chemical composition. One-way and two-way ANOVA were used for statistical analysis using GraphPad{\textregistered} PRISM Version 6. Results: Fractionation of aqueous S. polyanthum leaves extract (ASP) afforded nine fractions, later combined into three fractions (F1ASP, F2ASP, and F3ASP) based on the thinlayer chromatography profiles. ASP has the highest TPC while F2ASP has the lowest TPC. All fractions exhibited significant antihypertensive property, but F2ASP was the most active fraction. Few phenolics with related antihypertensive effects such as 1-galloyl glucose (a gallic acid-derivative majorly found in F2ASP and F3ASP), and other compounds such as polydatin, sesamol, brazilin, eugenol, ellagic acid, kukoamine A, and cyclocurcumin were found across all active fractions. Conclusion: These phenolics may partly contribute to the antihypertensive effect of S. polyanthum leaves, thus further isolation study is recommended.

Introduction: Guava (P. guajava), bay (S. polyanthum), and soursop (A. muricata) known as natural medicine. Limited report is available on their antioxidant and α-glucosidase inhibitory activities of leaf infusion. The aims of this research were to compare the antioxidant and α-glucosidase inhibitory activities of leaf infusion from guava, bay, and either as individual or combined infusions, and to analyze the chemical composition of the leaf infusion. Methods: Air dried leaf powder of guava, bay and soursop were infused separately with boiled aquadest. The infusions were analyzed for their antioxidant activity against DPPH. The α-glucosidase inhibitory assay was conducted against α-glucosidase from Saccharomyces cerevisiae. Then the infusions scanned with UV-Vis spectroscopy and analyzed with LC-MS. The synergism activities of the combined infusion were measured. Results: Antioxidant activities of leaf infusions of guava and bay showed a comparable result IC50 12.53 {\textpm} 0.55 and 10.76 {\textpm} 0.20 μg GAE/mL, but the infusion of soursop showed lower (IC50 19.77 {\textpm} 0.35 μg GAE/mL) than BHT as positive control (11.6 {\textpm} 0.31 μg GAE/mL). If soursop infusion was not added, then the mixture of the guava and bay infusion showed an antioxidative synergistic effect. The α-glucosidase inhibitory activities of the guava, bay and soursop infusion (0.083 {\textpm} 0.01; 0.025 {\textpm} 0.007; 0.533 {\textpm} 0.039 μg GAE/mL, respectively) were stronger than acarbose (1285 {\textpm} 148 μg/mL). The α-glucosidase inhibitory activities of the combined infusions showed a synergistic effect. The main constituents of the guava infusion were identified tentatively as chrysin and caffeoylquinic acid, for the bay infusion it was caffeoylquinic, and for the soursop infusion it was luteolin. Conclusions: There is a significant synergism of antioxidant activity of Guava and Bay mixture. The combined infusion of Bay and Soursop or Guava and Soursop showed antagonistic effect.

Context: Aqueous decoction of Syzygium polyanthum (ADSP) leaf is one of Malay traditionalremedial- preparations for hypertension. Intravenous ADSP reduced blood pressure of anesthetized Wistar-Kyoto (WKY) and Spontaneously-Hypertensive rats (SHR); however, acute and sub-acute effects of oral ADSP on conscious rats and its bioactive compound(s) are not comprehensively studied. This study aims to examine the acute and sub-acute effects of ADSP in comparison to methanol extract (MESP) on systolic blood pressure (SBP) of conscious WKY and SHR rats, as well as to identify their major phenolic-compound using highperformance- liquid-chromatography (HPLC). Methodology: For acute study, SHR and WKY rats were gavaged with single-dose of ADSP or MESP (2.00, 2.50 or 3.00 g/kg), vehicles, or losartan (0.01 g/kg). SBP was measured after 1, 3, 5, 6 and 24 hr-post-administration. For subacute experiment, SHR rats were gavaged once-daily with ADSP or MESP (2.50 g/kg/day), vehicles, or losartan (0.01 g/kg/day) for 3-week and their SBP was weekly-measured. Phenolic compounds were screened using ferric-chloride test, then gallic acid was determined using HPLC. Results: Acute administration of ADSP (2.50 to 3.00 g/kg) and MESP (2.00 to 3.00 g/ kg) significantly reduced SBP of SHR, but not of WKY rats. Repeated-daily-dose administration of MESP (2.5 g/kg/day) significantly reduced SBP of SHR after 2-week and sustained until 3-week, while ADSP (2.5 g/kg/day) significantly reduced SBP only after 3-week. Gallic acid was the major phenolic-compound in ADSP (157.09 \± 4.18 ppm) and MESP (134.04 \± 10.30 ppm). Conclusion: Oral ADSP and MESP that contain gallic acid possess acute and sub-acute antihypertensive effects in SHR, but MESP\’s effect was more prominent than ADSP

Context: Syzygium polyanthum has been traditionally formulated by the folklore for the treatment of diseases including diarrhea, rheumatism, diabetes mellitus, hypercholesterolemia, hypertension, gastritis and hyperuricemia. Normally, its phytochemicals are always extracted using solvent, maceration and steam distillation methods, but the use of ultrasound-assisted extraction (UAE) method is still not well documented. Aims: This study aims to extract the phytochemical compounds present in S. polyanthum leaves using UAE and to identify them by Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Methodology: The leaves were consecutively soaked with n-hexane, ethyl acetate and methanol in a bath sonicator to derive n-hexane (HSP), ethyl acetate (EASP), and methanol (MSP) extracts of S. polyanthum leaves and then the extracts were subjected to GC-MS analysis. Mass-spectral databases of peaks were compared with database from Wiley, NIST and FNSCC libraries for compound identification. Results: GC-MS analyses of HSP, EASP and MSP showed the presence of 21, 27, and 31 peaks, respectively. The major compound for HSP (31.912\%), EASP (27.042\%), and MSP (22.386\%) were unknown compounds which were detected at retention time between 61.980 and 62.29 min, thus requires further characterization. Squalene and phytol were among the other major compounds present in all three extracts. Several identified compounds in the extracts such as squalene, phytol, hentriacontane, palmitic acid, \α-pinene, nerolidol, linalool, \α-tocopherol and \β-tocopherol were known bioactive compounds. Conclusion: GC-MS analyses of n-hexane (HSP), ethyl acetate (EASP), and methanol (MSP) of S. polyanthum leaves extracts have revealed the presence of some known bioactive compounds with therapeutic importance.
