“…The synthesis and assembly of metallic and metal oxide nanoparticles would be beneficial towards the development of clean, non-toxic, and environmentally acceptable "green chemistry" procedures [12][13][14][15]. Nanobiotechnology is an alternative route for the synthesis of biocompatible stable nanoparticles [16,17].…”

Biosynthesis using plant extract is known as one of the potential techniques to synthesize different zinc oxide nanoparticles (ZnO-NPs) in different size ranges. ZnO-NPs were synthesized using Plumeria leaf extract with laboratory chemical reagent Zn(CH3COO)2 and followed by the micro-encapsulation of biosynthesized ZnO-NPs using chitosan and cellulose with TEOF as a cross-linker employing freeze gelation method. Both neat and encapsulated ZnO-NPs have been characterized by FT-IR, UV spectroscopy, XRD, and SEM techniques. The UV-spectroscopic analysis confirmed the characteristic band of ZnO-NPs at 356.0 nm, and FIIR showed the peaks at 544 cm−1 and 545 cm−1 corresponding to the Zn–O bond. Powder XRD pattern showed the wurtzite structure of ZnO and gave the calculated average crystallite size as of 27.23 nm. In the case of encapsulated ZnO-NPs, the UV–visible spectrum showed two strong absorption peaks at 232.5 nm, 242.5 nm, and a weak peak at 357 nm. A broad peak at 3333 cm−1 in FT-IR spectra is either due to N–H stretching in the amide group of chitosan or hydroxyl group in encapsulated ZnO-NPs. It was observed that chitosan loaded ZnO-NPs had higher entrapment efficiency (81.98%) at 15 mL of plant extract. The kinetic profile in the release of ZnO particles out from encapsulated ZnO-NPs was observed to follow four kinetic paths in 120 min at pH 1.2. The particle release followed the zero-order kinetic in the first 50 min and then followed by Hixson–Crowell kinetic in the next 50 min with two different rate constants, 2.6 × 10−3 min−1 and 13 × 10−3 min−1, before it backs to the zero-order kinetics. This study shows that ZnO nanoparticles can easily be biosynthesized and encapsulated for use in the pharmaceutical industry.

Plumeria obtuse L. (Apocynaceae) is an ornate outdoor plant. The plant was traditionally used during accidentalinjuries. However, the pharmacognosy of this plant is very poorly explored. Therefore, we have conducted this study to assess the distinctive qualities of the P. obtusa. To investigate P. obtusa seed pods’ preliminary pharmacognostic, physical-chemical, phytochemical, microscopic, and phytoconstituent potential. Initially, the shape and microscopic characteristics of plant seed pods were assessed. Physicochemical analysis was used for the standardization. Utilizing several chemical techniques, phytoconstituents were evaluated qualitatively. This was followed by quantitative estimation and analytical profiling of various phytoconstituents. The basic characteristics of the seed pod have been documented by macroscopy to be its brown color, sweet aroma, bitter flavor, coarse texture, and rough fracture. Microscopy showed the existence of vascular bundles, lignified fibers, calcium oxalate crystals and arteries. The results of the physicochemical analysis revealed no foreign organic matter, 2.8 % weight-average moisture content and a high total ash value of 14.80 compared to an acid insoluble ash value of 0.70, which indicated that there was less inorganic matter in the plant. The extractive values were 3.93, 6.03 and 10.16 % w/w for water soluble, alcohol soluble and hydro-alcoholic soluble extracts respectively. Flavonoids, glycosides, saponins, phenolic constituents, tannins and carbohydrates were found during early phytochemical analysis. Instrumental analysis has given an idea about functional groups present whereas GCMS technique helped in identification of phytoconstituents. The results of this study can be significantly used as a reference support for quality control and standardization of P. obtusa and preparation of a monograph of plant.

“…Numerous biological actions reported by Sansevieria species includes antibacterial, free radical scavenging, antidiabetic, anticancer, and capillary permeability suppression (14). The Apocynaceae family includes the Plumeria obtusa plant, which is found in Florida, Greater Antilles, Northern, Central America and southern Mexico (15). The Plumeria is used as an emmenagogue, rubefacient, stimulant, febrifuge, hemostatic, purgative, laxative, and vermifuge among many more medical purposes (16,17).…”

Background: Sansevieria cylindrica and Plumeria obtusa are used as a medicinal plant during intentional and unintentional accidental injuries. However, limited investigations have been performed to study pharmacological activities of these plants. Objectives: The current study designed at examining in-vitro anti-inflammatory and anti-oxidant effect of both plant extracts. Material & Method: Initially, the collection and authentication of both the plants performed. Phytochemical screening was done thereafter. Sansevieria cylindrica leaves and Plumeria obtusa seed pods were extracted using a combination of water and ethanol. Anti-inflammatory effect was assessed using membrane stabilization and protein denaturation assays. Anti-oxidant activity was measured by free radicals scavenging method using different reactive oxygen species producing reagents. Results: The dose dependent increase in anti-inflammatory and anti-oxidant activities were reported by both plants. Overall, Sansevieria cylindrica has shown higher rate of prevention of inflammation and oxidation compared to Plumeria obtusa extract. Both plants showed comparable anti-inflammatory and anti-oxidant activity in combination with that of reference drugs. Conclusion: The hydro-alcoholic extracts of Sansevieria cylindrica and Plumeria obtusa individually and also as 1:1 blend might be responsible for an anti-inflammatory and anti-oxidant activities.
