Marchantia Paleacea

Immunostimulants are compounds that can stimulate an immune response by increasing the activity of non-specific and specific components of the immune system (humoral and cellular) against certain infections and diseases. The liverwort plant species Marchantia paleacea Bertol. has long been used as a source of nutrition and empirical medicine. However, scientifically there is still not much research data on immunomodulators in these plants. This study aims to determine the activity of immunomodulators in the ethanol extract of the herb Marchantia paleacea Bertol. in male mice of BALB/c strain. Bioactive compounds from this plant were extracted by maceration method using 96% ethanol. Extract characterization and phytochemical screening were determined according to WHO guidelines and standard procedures from previous studies. The immunomodulatory activity of the extract was tested by carbon clearance method and lymphoid organ index (non-specific responses), primary and secondary antibody titer tests (humoral specific responses), IL-2 cytokine levels and IFN-ɣ from serum secondary antibodies and delayed-type hypersensitivity reaction/DTH (cellular specific response). The results of qualitative phytochemical screening contained flavonoid compounds, saponins, phenolics, tannins and steroids/triterpenoids. The results of the non-specific immune response immunomodulator test showed that the dose of 52 mg/kg bw had the largest phagocytic index of 1.52 which included strong immunostimulation (K > 1.5) and the organ spleen index of 0.55 ± 0.11 which increased significantly compared to the control (p<0.05). The data on the acquisition of specific immune responses in the primary and secondary antibody titer test in the three test extracts resulted in increased titer levels compared to the control and at a dose of 52 mg/kg bw could significantly increase the levels of IL-2 cytokines in the control group (p<0,05). Meanwhile, in the DTH test, doses of 13 and 26 mg/kg bw could significantly increase the thickness of the soles of mice compared to controls (p<0.05).

Abstract. Yuandani, Nugraha SE, Laila L, Silaban SD, Ramadhani F. 2020. Short Communication: Stimulatory effect of Curcuma mangga on immune response against Staphylococcus aureus. Nusantara Bioscience 12: 109-113. Recently, the ethanol extract of Curcuma mangga Val. rhizomes were found to have immunomodulatory activity by enhancing phagocytic ability. This study was carried out to evaluate the effect of C. mangga rhizomes on antibody titer and delayed-type hypersensitivity response in normal and doxorubicin-induced rats against Staphylococcus aureus. The extract was administered orally at doses of 100, 200, and 400 mg/kg body weight (bw) to rats for 72 hours prior to sensitization of Staphylococcus aureus, then continued for 14 days. Doxorubicin (4.67 mg/kg bw) was administered on days 8 and 11 to suppress the immune system. The antibody titer of normal and immune-suppressed rats after the treatment with C. mangga ethanolic extract was significantly higher than the rats with negative control (P<0.05). Ethanol extract of C. mangga also demonstrated stimulation on delayed-type hypersensitivity response which was indicated by the increase of paw volume. The extract at dose of 400 mg/kg bw showed higher immunostimulatory activity than Levamisole as a positive control. The results indicated that the ethanol extract of C. mangga shows immunostimulatory activity, confirming its potential to be developed as a therapeutic agent.

This study aims to evaluate the bioactive components, in vitro bioactivities, and in vivo hypoglycemic effect of P. frutescens leaf, which is a traditional medicine-food homology plant. P. frutescens methanol crude extract and its fractions (petroleum ether, chloroform, ethyl acetate, n-butanol fractions, and aqueous phase residue) were prepared by ultrasound-enzyme assisted extraction and liquid–liquid extraction. Among the samples, the ethyl acetate fraction possessed the high total phenolic (440.48 μg GAE/mg DE) and flavonoid content (455.22 μg RE/mg DE), the best antioxidant activity (the DPPH radical, ABTS radical, and superoxide anion scavenging activity, and ferric reducing antioxidant power were 1.71, 1.14, 2.40, 1.29, and 2.4 times higher than that of control Vc, respectively), the most powerful α-glucosidase inhibitory ability with the IC50 value of 190.03 μg/mL which was 2.2-folds higher than control acarbose, the strongest proliferative inhibitory ability against MCF-7 and HepG2 cell with the IC50 values of 37.92 and 13.43 μg/mL, which were considerable with control cisplatin, as well as certain inhibition abilities on acetylcholinesterase and tyrosinase. HPLC analysis showed that the luteolin, rosmarinic acid, rutin, and catechin were the dominant components of the ethyl acetate fraction. Animal experiments further demonstrated that the ethyl acetate fraction could significantly decrease the serum glucose level, food, and water intake of streptozotocin-induced diabetic SD rats, increase the body weight, modulate their serum levels of TC, TG, HDL-C, and LDL-C, improve the histopathology and glycogen accumulation in liver and intestinal tissue. Taken together, P. frutescens leaf exhibits excellent hypoglycemic activity in vitro and in vivo, and could be exploited as a source of natural antidiabetic agent.

Significant Stimulatory Effect

Phyllanthus species (Family Euphorbiaceae) has been used in traditional medicine of several countries as a cure for numerous diseases, including jaundice and hepatitis. This study is an attempt to evaluate the immunomodulatory activity of various fractions, column eluents of ethyl acetate fraction, and their polyphenols. Phyllanthus maderaspatensis were standardized using high-performance liquid chromatography to identify and quantify polyphenols, and purification of polyphenols was carried out using vacuum liquid chromatography. Subsequently, we tested various fractions, column eluents of ethyl acetate fraction, and polyphenols in vitro to assess their impact on nitric oxide (NO) production in LPS-stimulated mouse macrophage RAW 264.7 cells. The ethyl acetate fraction (100 μg mL−1) had a more significant stimulatory effect on LPS-stimulated NO production by the RAW 264.7 cells. We found that the ethyl acetate fraction contains a high amount of catechin, quercetin, ellagic acid kaempferol, and rutin, which are responsible for immunomodulation. The ethyl acetate fraction at concentrations of 25 and 50 μg mL−1 had a significant inhibitory effect and 100 μg mL−1 had a more significant stimulatory effect when compared with the LPS control. The percentage of inhibition by LPS control ranged from zero percentage, kaempferol ranged from 45.4% at 50 μg mL−1 to 41.88% at 100 μg mL−1, catechin ranged from 50% at 50 μg mL−1 to 35.28% at 100 μg mL−1, rutin ranged from 36.2% at 50 μg mL−1 to 47.44% at 100 μg mL−1, gallic acid ranged from 28.4% at 50 μg mL−1 to 50.9% at 100 μg mL−1, ellagic acid ranged from 45.12% at 50 μg mL−1 to 38.64% at 100 μg mL−1, and purified quercetin ranged from 26.2% at 50 μg mL−1to 45.48% at 100 μg mL−1. As NO plays an important role in the immune function, polyphenols’ treatment could modulate several aspects of host defense mechanisms owing to the stimulation of the inducible nitric oxide synthase.

Zapoteca portoricensis (Jacq) HM. Hernández popularly called “Elugelu” belongs to the Fabaceae family. It is reportedly used in traditional medicine as anti-diarrhoea, anticonvulsant, antispasmodic and in management of autoimmune disorders. The immunomodulatory activity of methanol root extract and fractions of Zapoteca portoricensis was evaluated using three experimental models: neutrophil adhesion, haemagglutination antibody (HA) titre and delayed hypersensitivity (DTH) of an immune response in mice. Five (5) groups of mice (n=5) were used; group I was the normal control; group II was the standard control (levamisole, 2.5 mg/kg) while groups IIIA–C, IVA–C and VA–C received graded doses (25, 50, 100 mg/kg) of methanol extract (ME), ethyl acetate fraction (EF) and methanol fraction (MF), respectively. Sheep red blood cells (SRBCs; 0.1 ml) were injected subcutaneously to sensitize the animals. The study results showed that the methanol fraction (MF) exhibited the highest percentage (46.12%) in neutrophil adhesion followed by the ethyl acetate fraction (EF) (37.06%) at 100 mg/kg dose, respectively, compared with the normal control. The highest percentage increase in both primary and secondary antibody titre was found to be ME (85.19%, 43.20%), EF (91.53%, 102.67%) and MF (128.31%, 111.89%) at 50 mg/kg dose, respectively compared to the normal control. The EF at the doses of 25 and 50 mg/kg produced the highest percentage inhibition (56.57%, 58.33%) in DTH response, respectively, followed by MF (42.46%) at a dose of 25 mg/kg. Oral administration of Z. portoricensis exhibited immunomodulatory effects on specific components of the immune system in mice.

Background: The immune system is intrinsic to health. Modulation of the immune responses to alleviate the diseases by using herbal plants has been of interest for many years. Diosgenin, a naturally occurring steroid saponin mainly present in the seeds of fenugreek (Trigonella foenum graecum) and in the root tubers of wild yams (Dioscorea villosa). Activation of specific and nonspecific immunity results in stimulation of immune response. Diosgenin has the positive effects on both specific and nonspecific immunity. Aim: To study the immunomodulatory activity of Diosgenin in albino wistar rats. Method: The suspension of Diosgenin was given orally at the dosage level of 50, 100 and 150 mg/kg for 21 days in a rat. The immunomodulatory activity on specific and non-specific immunity was studied by heamagglutination antibody (HA) titer, delayed type hypersensitivity (DTH) response and carbon clearance test.  Immunosuppression in a rat was induced by using Cyclophosphamide (100 mg/kg, p.o.). Sheep red blood cells (SRBCs) were used as antigen (0.1ml 20% SRBCs). Result: Diosgenin exhibited significant increase in the production of antibody titer in response to SRBC antigen. A significant increase in both primary and secondary HA titer was observed in immunosuppressed group treated with Diosgenin when compared with negative control.  A significant increase in the DTH response was observed in immunosuppressed animals treated with Diosgenin, pre-sensitized with SRBCs antigen. Diosgenin exhibited significant increase in phagocytic index against control group, indicating the stimulation of the reticuloendothelial system. Conclusion: The study indicates that Diosgenin triggers stimulatory effect on specific and nonspecific immune response. The immunostimulant effect of Diosgenin could be attributed due to its saponin glycoside.
