Abstract

The paper reports the antioxidant activity of a non-volatile fraction of lime processing byproducts from the lime syrup home industry. The activity was measured by spectrophotometry to obtain the 50% inhibition concentration (IC50) using the 2,2- diphenyl-1-picrylhydrazyl (DPPH) method. The sample was extracted by the maceration method with n-hexane, ethyl-acetate, and ethyl-ethanol. The IC50 values of 681 ppm, 458 ppm, and 2,775 ppm were n-hexane, ethyl-acetate, and ethyl-ethanol. The experiments concluded that the ethyl-acetate extract provides the best inhibition value to scavenge free-radicals DPPH. The HPLC and mass spectroscopy were measured to find out the content and group of active compounds. The significant compounds consisted of naringin, poncirin, or neoponcirin, which are known as antioxidant substances. The result shows the potential application of the lime by-products, its volatile fraction, and the nonvolatile fraction, which is the production residue of lime peel. This work can be applied as an alternative to zero-waste lime production, which may benefit the industry and the environment.

Abstract

The chrysanthemum plant (Chrysanthemum morifolium Ramat.) contains many secondary metabolites such as flavonoids and various volatile compounds that can be utilized as drugs. Tissue culture can be an alternative to enhance the production of certain secondary metabolite. The study aimed to determine the types of secondary metabolites that contained in shoot culture, callus and field plants of C. morifolium. The research method was exploration in the laboratory to analyze and compare the content of secondary metabolite from shoot culture, callus and field plants of C. morifolium. Callus was induced by explants of C. morifolium plantlet stems and leaves respectively on MS medium with an addition of 3 ppm 2,4-D + 2 ppm kinetin and 4 ppm 2,4-D. For shoot culture, single nodule explants with one leaf were planted on MS media with the addition of 1 ppm BAP. The secondary metabolite compouds were analized and identified by GC-MS (Gas Chromatography-Mass Spectrometry). The results showed that various types of secondary metabolites contained in shoot culture, callus and field plants of C. morifolium. In callus culture from leaf explants, four compounds from groups of alcohol, acetic acid and organosilicon were identified, whereas in callus culture from stem explants were identified eight compounds from aldehydes, esters, alkanes, and carboxylic acids group. In the shoot culture, nine compounds of alcohol, ketone, aldehyde, cycloalkane and organosilicon group were identified, while in the field plants five compounds were identified from the cycloalkanes, ketones, organoborones and organosilicon group. Some detected compounds have a potential as precursors of alkaloid, phenolic, and flavonoid.Keywords: chrysanthemum, culture, shoots, callus, secondary metabolites.

Abstract

Light intensity in plants influences their growth potential as well as their morphological, anatomical, and physiological structures. This study aimed to observe the leaf area, leaf thickness, leaf type, stomatal type, stomatal density, chlorophyll content, and phytochemical content of Sente leaves (Alocasia macrorrhizos) in two locations with different light intensities. This exploratory research used a survey method to determine the research location, and environmental parameter measurements was used as supporting data. Morphological and anatomical parameters and chlorophyll content were assessed using a quantitative approach, while phytochemical content was determined qualitatively and analyzed descriptively. The results showed differences in the morphology, anatomy, chlorophyll content, and phytochemicals of Sente leaves in varying light intensities. Morphologically, the leaves of Sente plants in shaded locations had larger surface areas, were thinner, and appeared greener compared to those in unshaded locations. The stomatal density of leaves in unshaded areas was higher (76.43 cells/mm ²) compared to shaded areas (56.05 cells/mm ²). The chlorophyll content in shaded locations was higher (82.03 CCl) than in unshaded locations (41.7 CCl). Phytochemical tests for flavonoids and saponins showed higher compound levels in leaves from unshaded locations, while tannin tests revealed higher levels in shaded locations compared to unshaded ones. Meanwhile, tests for alkaloids and quinones yielded negative results.

Abstract

This study examines the stomatal characteristics and leaf thickness of six species within the Liliales: Gloriosa superba, Sansevieria trifasciata, Aloe vera, Cordyline terminalis, Pleomele angustifolia, and Allium fistulosum. Stomatal density, type, and distribution were measured to understand their relationship with leaf morphology. The results show that Gloriosa superba has a stomatal density of 148.72/mm² and an index of 0.295, with thin leaves. Sansevieria trifasciata, with its thick, fleshy leaves, has a lower stomatal density of 15.39/mm² and an index of 0.031. Aloe vera, another species with thick leaves, has a stomatal density of 38.47/mm² and an index of 0.067. In contrast, Cordyline terminalis and *Pleomele angustifolia, which have thin leaves, exhibit higher stomatal densities of 192.31/mm² and 128.21/mm², respectively. Their stomatal indices are 0.092 for Cordyline terminalis and 0.163 for Pleomele angustifolia. Allium fistulosum also has thin leaves, with a stomatal density of 100/mm² and a high stomatal index of 0.390. The study reveals that species with thicker leaves tend to have lower stomatal densities, a feature that helps reduce water loss in arid environments. These findings contribute to a deeper understanding of plant adaptation mechanisms and have implications for improving water-use efficiency in agriculture and conservation efforts.

Abstract

Rice-washed water is wastewater resulted from the rice cleaning process that is rich in nutrients. The use of ramie chip waste can be considered a potential substrate due to its lignocellulosic nature, similar to other wastes studied. This study aimed to examine the effect of rice-washed water on the mycelium and pinhead growth of white oyster mushrooms grown in the ramie chip waste as the growing medium. The experiment was conducted for three months using a completely randomized design with four rice-washed water treatments and six replications. The rice-washed water concentration treatments were 0% (K0), 25% (K1), 50% (K2), and 100% (K3), which were added to the ramie chip waste as the growing medium for white oyster mushroom. The time of mycelium propagation velocity, the time the first pinhead appearance, the number of mushroom bodies, and the largest cap diameter were observed. The results showed that ramie chip waste-derived media was suitable to cultivate white oyster mushrooms. Adding 100% rice-washed water to the media significantly affected the speed of mycelium propagation (16.51 days) compared to control (30 days) and the appearance of the first pinhead (31.5 days) compared to control (38.5 days) as well as the number of fruiting bodies of mushroom (8.8) compared to control (6.2). However, the rice-washed water application did not significantly affect the diameter of the largest mushroom cap.

Abstract

Bidens pilosa is a plant known for its secondary metabolites with therapeutic properties. This study aimed to examine the effects of different light intensities on the morphology, anatomy, chlorophyll content, and secondary metabolite production of B. pilosa in the Arboretum of Universitas Padjadjaran. The shaded and unshaded area had light intensities of 5828 and 32768 lux, respectively. Leaf samples were collected from three different individuals in each area, with three leaves taken per plant. Morphological and anatomical traits such as leaf thickness, leaf area, stomatal density, and chlorophyll content were observed, along with secondary metabolite content. Results showed that plants in the shaded area had thinner leaves (0,19 mm) and lower stomatal density (275,16 cells/mm2) but a larger leaf area (4 cm2) and higher chlorophyll content (29,33 CCI) compared to leaves in the unshaded area, which had thicker leaves (0,213 mm), higher stomatal density (310,83 cells/mm2), a smaller leaf area (2,33 cm2), and lower chlorophyll content (27,27 CCI). Alkaloids, flavonoids, tannins, and saponins were detected in both conditions, with a higher level of alkaloid and tannin in unshaded plants. These findings enhance our understanding of the relationship between light intensity influences plant morphology, photosynthesis, and secondary metabolite production, with potential applications in cultivation and medicinal use.

Abstract

Introduction: Streptococcus mutans has been known to play a major role in dental caries development. This tooth decay is the most common oral disease affecting people in the world. Hence, discovering the new herbal antibacterial agent seems to become more promising yet challenging. One of natural antibacterial source is the peel of Citrus aurantifolia, as it may contain antibacterial active compounds against pathogenic oral microbes. This study was aimed to isolate antibacterial compound from essential oil of Citrus aurantifolia and to analyse its antibacterial activity against oral Streptococcus mutans ATCC 25175. Methods: Type of research was laboratory experimental. The essential oil was isolated from peel of Citrus aurantifolia by hydro-distillation technique and further isolation of antibacterial compounds was conducted by combination column chromatography using organic solvent, and the structure was determined by UV-Vis, infrared (IR), 1D NMR of 1H-, 13C-NMR and DEPT 135° in CDCl3 spectrometers methods. The antibacterial activity was tested against Streptococcus mutans ATCC 25175 using the Kirby-Bauer method. Results: 0.75% yield was obtained from the essential oil of peel Citrus aurantifolia and after purification, an antibacterial compound was identified as β-pinene with the molecular formula C10H16. Furthermore, the β-pinene from peel of Citrus aurantifolia exerted inhibition growth against Streptococcus mutans at concentration of 2000, 1000, and 500 ppm by showing respectively, inhibition values of 13.0, 11.9, and 11.6 mm on paper disk. Conclusion: In the present study, the essential oil of Citrus aurantifolia peel is proven to contain prospective antibacterial compound (β-pinene) that potentially can be used as natural antibacterial alternative choice to manage oral disease associated with Streptococcus mutans infection.
