Finding the ecofeminist voice in the Palanca winning short stories of Alice Tan-Gonzales
(2021)
This study shows the deep connection of women and nature thru the ecofeminism lens. This pioneering study takes a deeper look into how ecofeminism is illustrated in the Palanca winning short stories of Alice Tan-Gonzales and explains that ecofeminism is a strong subject in her short stories’ Sa Taguangkan sang Duta and Baha specifically anchoring it on spiritual and cultural ecofeminism. This study also theorizes how the value of ecofeminism present within Gonzales’ short stories can help shed light on the female struggle that exists within Western Visayan society, identify the various ecofeminist elements, specifically the characters and the setting in the stories, and illustrate why these are elements of ecofeminism, and problematize on the selected works of Alice Tan Gonzales and categorize her position as a defining writer in West Visayas Literature. The analysis determined that ecofeminism is present within Gonzales’ short stories as illustrated by the characters’ revelation of the current female struggles in the region. Through a thorough discussion, a clear illustration of ecofeminism was achieved. Results of the study revealed that through the characters and setting, and Alice Tan Gonzales’ literary works is undeniably an embodiment of reality that separates her from other writers in the Western Visayan region. This should encourage extensive information dissemination about the real plight of women and nature’s current state to increase awareness and aid in the mitigation of the situation....

Antibacterial activity of balloon vine (Cardiospermum halicacabum L.) leaf and fruit crude extracts, and their combination against Staphylococcus aureus
(2022-08)
Staphylococcus aureus the leading cause of bacterial infections in hospitals and communities such as abscesses (boils), furuncles, and cellulitis is a major pathogen of increasing importance due to the rise in antibiotic resistance. Cardiospermum halicacabum a well-known plant was investigated to explore its capacity against bacterial activity such as S. aureus that would be useful in the production of compounds that can inhibit other pathogenic bacteria and other pathogenic microorganisms. This study attempted to extend such concept and explore the possibility of using halicacabum as possible agent in controlling human pathogens specifically the aureus. The mean (M) was used in order to determine the average zone of inhibition of aureus applied with balloon vine (C. halicacabum) leaf, fruit, and combined extracts, Amoxicillin (Positive control), and Ethanol (Negative control). Using the disc diffusion method, the crude extract of C. halicacabum showed that the greatest zone of inhibition of S. aureus was observed among those applied with Amoxicillin (M= 52mm), followed by those applied with balloon vine fruit extract (M=44mm) Both leaf extract (M=31mm and the combined leaf and fruit extract (M=30mm) also significantly exhibited inhibition against the S. aureus. There is no zone of inhibition observed among those applied with Ethanol (M=.00mm). The One-Way ANOVA test result shows that the p-value is .000 which is deemed to be statistically significant if p<.001....

Potential alpha-amylase and alpha-glucosidase inhibitory activity of bioactive fractions from alugbati (Basella alba) leaves
(2022-06)
This study evaluated the potential in vitro inhibitory activity of Basella alba leaves against enzyme markers of diabetes mellitus, α-amylase, and α-glucosidase. The dried plant sample was ground into fine powder, defatted, and soaked in methanol to obtain the crude extract. The crude methanolic extract of Basella alba was then fractionated sequentially in acetone-methanol mixtures with increasing solvent polarity ratios. Fractions obtained were evaluated for their α-amylase and α-glucosidase inhibitory potential. The standard drug, acarbose inhibited 37.44 ± 7.65%, 83.99 ± 0.86%, and 86.52 ± 0.40% of α-amylase activity at 10, 30, and 50 ppm. The highest inhibition was observed in the acetone-methanol (4:1) fraction which inhibited 57.80 ± 0.71%, 56.39 ± 0.49%, and 46.94 ± 0.26% of α-amylase activity, followed by the acetone fraction with inhibitory activity of 22.24 ± 0.41%, 38.05 ± 0.68%, and 46.62 ± 0.32% at increasing concentrations of 50, 200, and 350 ppm, respectively. The acetone-methanol (1:4) mixture exhibited the lowest activity at 8.00 ± 0.35% for 50 ppm, and 0.61 ± 0.27% for 200 ppm. However, no inhibitory activity was demonstrated in any of the fractions of Basella alba against α-glucosidase. Total flavonoid content analysis revealed that all fractions have the same flavonoid content. Basella alba may serve an essential role in managing the risk of diabetes mellitus and is recommended for consumption on a regular basis....
Use of blue ternate (Clitorea ternatea Linn.) and karonda (Carissa carandas Linn.) fruit and flower extract as alternative bacterial stain
(2022-08)
It has been known that bacterial staining is one of the fundamental procedures done when identifying microorganisms, hence, learning about it and obtaining skills to perform it has been given great importance. This activity led to the constant exposure of the students and researchers, alike, to the chemicals used to achieve results. The chemicals used, or in this case, the dyes, were synthetic in nature, thus they pose possible danger to those who are continuously using it. The purpose of this study is to determine the possibility of karonda (C. carandas) fruit and blue ternate (C. ternatea) flower crude extracts as alternative bacterial stains by observing their staining intensities on S. aureus. Methylene blue served as the positive control. Tannic acid was added as a mordant to the crude extracts and staining intensity was based on the Likert scale. Results showed that blue ternate flower had a mean score of 0.8 (low staining intensity), blue ternate with tannic acid had a mean score of 1.8 (average staining intensity) while karonda fruit crude extract had a mean score of 1.0 (low staining intensity), karonda with tannic acid had 1.2 (average staining intensity) compared to the control group which had a mean score of 3.0 (very high staining intensity. This means that the staining intensity of the crude extracts obtained from natural sources were way beyond the staining intensity of methylene blue which is of synthetic origin....
