Journal of Practical Medicine 2002;435(11):22-25
Helicobacter pylori’s role in pathogenesis of gastroduodenitis and gastroduodenal ulcer has been documented in recent studies. Treatment efficacy has been changed because H.pylori get more and more persistent to treatment. Using antibiotic from herbal is the aim of our study. A product extracted from Piper beetle. L, a strongly antibiotic agent in vitro, can eradicate HP? The specimen was taken from gastric mucosa of patients with gastritis. These specimens have been crushed and cultured in brain- heart agar medium in the atmosphere of 10% CO2, and to: 37oC. If the bacteria developed, we would measure their sensitivity to total extract (Betelvine) from Piper beetle. L. 35 strains of HP developed from 56 specimens were assessed their sensitivity by using round paper pieces, which had been soaked with or Betelvine, either Tetracycline, Ampicilline, metronidazole- 100% strains of HP were sensitive to Betelvine with antibacterial rings from 12mm to 40mm.- 100% strains of HP were not sensitive to metronidazole, all antibacterial rings of metronidazole were O mm. 3,32% strains of HP were not sensitive to Tetracycline. - 12,9% trains of HP weren’t sensitive to Ampiciline.

Aims:
Piper nigrum L. (black pepper) is an economically important commodity plant in Malaysia, which generated RM
200.95 million from pepper export in the year of 2018. However, the increase in pepper production is restricted by
diseases. Fusarium wilt is one of the major diseases of P. nigrum L. The objectives for this study were to isolate
Fusarium spp. associated with Fusarium wilt of P. nigrum L. from selected pepper farms in the northwestern region of
Sarawak and to characterize the Fusarium spp. isolated morphologically and molecularly.
Methodology and results:
Fusarium spp. were isolated from diseased root samples. The pathogen was grown on
potato dextrose agar (PDA) under dark condition at circa (ca.) 25 °C for morphological characterisation. Molecular
characterisation was done by using internal transcribed spacer (ITS). Phylogenetic tree was constructed to study the
genetic relationship of the isolates. Fusarium solani, F. oxysporum, F. proliferatum were the three Fusarium species
identified. There were variations in morphological characters observed between and among the species, including the
colony form, margin, elevation, surface appearance and pigmentation. No distinctive morphological characteristic was
specific to a location. In addition, growth rate, macroconidia sporulation rate, and microconidia sporulation rate of the
isolates were not correlated. In molecular phylogeny, the three Fusarium species were separated into three distinct
clades representing the three identified species. The genetic relatedness between isolates within each species was
depicted in the tree.
Conclusion, significance and impact of study
Variations were observed among isolates in this study based on
morphological and molecular characterization. This study would contribute information on the variations of Fusarium
spp. associated with Fusarium wilt of P. nigrum L. from the northwestern region of Sarawak.

Aims:
This study aimed to determine the antibacterial activity of Piper betle L. leaf extract against Xanthomonas oryzae pv. oryzae that causes bacterial leaf blight in rice plant.
Methodology and results:
The antibacterial activity of the P. betle leaf extract (100, 50, 25 and 12.25 mg/mL) with four different solvents (methanol, ethyl acetate, hexane and acetone) was evaluated using a disc diffusion assay, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values. The inhibition zone of methanolic extract appeared to have the maximum diameter compared to those of other extracts, which is 32.67 mm at a concentration of 100 mg/mL, followed by 30.33 mm, 22.00 mm and 20.30 mm for the concentrations of 50 mg/mL, 25 mg/mL and 12.5 mg/mL, respectively. The MIC and MBC values of the methanolic extract were 0.625 mg/mL suggesting that the extract has a bactericidal effect on X. oryzae pv. oryzae (Xoo). The time-kill curve studies revealed that the 1× MIC (0.625 mg/mL) concentration of methanolic extract had a time and concentration-dependent killing effect on Xoo. Gas chromatography-mass spectrometry (GC-MS) analysis of methanol extract revealed the presence of eugenol acetate (29.53%), 4-allyl-1,2-diacetoxybenzene (29.51%) and 2,3-dimethyl benzoic acid (22.82%) as major compounds.
Conclusion, significance and impact of study
The methanolic leaf extract of P. betle was proven to have an effective inhibitory effect on Xoo and may have the potential to be used as an alternative management strategy for controlling rice diseases. In the future study, the methanolic leaf extract of P. betle is one of the recommendations to be applied in glasshouse and field trials.

Acta Medica Philippina 2023;57(12):53-60
Background and Objective:
Staphylococcus aureus is the leading cause of skin and soft tissue infections such as abscesses, furuncles, and cellulitis. Biofilm forming strains of S. aureus have higher incidence of antimicrobial resistance to at least three or more antibiotics and are considered as multidrug resistant. Since S. aureus biofilm-producing strains have higher rates of multidrug and methicillin resistance compared to non-biofilm-producing strains, the need for alternative therapeutic option is important. Furthermore, rates of methicillin-resistant Staphylococcus aureus (MRSA) in Asia remain high. Results of the study may provide support for the clinical uses of P. betle as a topical antibacterial and antiseptic in the treatment and prevention of infections involving the skin, mouth, throat, and indwelling medical devices. Thus, this study aimed to evaluate the in vitro antibacterial and antibiofilm activities of Piper betle L. ethanolic leaf extract (PBE) against a biofilm-forming methicillin-sensitive Staphylococcus aureus ATCC 29213 (MSSA).
Methods:
The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of PBE against MSSA were determined using the agar dilution assay. The biofilm inhibition and eradication assays using crystal violet were done to quantify the antibiofilm activities of PBE on MSSA biofilm.
Results:
PBE showed activity against MSSA in agar dilution assay with MIC and MBC values of 2500 μg/mL and
5000 μg/mL, respectively. At subinhibitory concentrations, PBE showed biofilm inhibition activity at 1250 μg/mL but a lower percent eradication of biofilms as compared to oxacillin was noted.
Conclusion
PBE showed antibacterial activities including biofilm inhibition against methicillin-sensitive Staphylococcus aureus ATCC 29213 (MSSA).

Piperis Longi Fructus, made from the mature and immature fruit spikes of Piper longum, is a commonly used Mongolian medicine. In recent years, researchers have gradually deepened the research on ethnic medicines and found that Piperis Longi Fructus has significant effects in adjusting blood lipids and anti-cancer. Its new chemical components and pharmacological activities are also constantly updated. Subsequently, the development and application of Piperis Longi Fructus have attracted extensive attention. Thus, it is quite urgent to establish and improve a quality evaluation system for the medicine. On the basis of summarizing the chemical components and pharmacological effects of Piperis Longi Fructus and understanding the new concept of quality marker(Q-marker), the components which can be used as its Q-markers were analyzed from the aspects of the genetic relationship, traditional medicinal effects and properties, rules of compounding and compatibility, absorbed components and testability. The research can provide reference for the establishment of a quality evaluation system for Piperis Longi Fructus.
