A modified microwave hydrodistillation and simultaneous extraction in a rotating state to obtain essential oil, rosmarinic acid, and polysaccharides with sucrose stearate as an additive from Perilla frutescens

Xinyu Yang et al.

Summary: An improved approach using microwave-induced hydrodistillation and simultaneous extraction (MHDE) was developed to obtain essential oil, rosmarinic acid, and polysaccharides from Perilla frutescens leaves. The yields of essential oil and rosmarinic acid were increased, and the content of perillaldehyde in the essential oil was higher compared to traditional hydrodistillation and extraction (HDE) method.

A comparative evaluation of statistical empirical and neural intelligence modeling of Manihot esculenta-derived leaves extract for optimized bio-coagulation-flocculation of turbid water

Heri Septya Kusuma et al.

Summary: In this study, the effectiveness of Manihot esculenta extract as an ecofriendly coagulant for treating turbid wastewater was evaluated. The coagulant was characterized chemically and morphologically, and the coagulation process was modeled using response surface methodology (RSM) and artificial neural networks (ANN). The results showed that the coagulant had diverse functional groups, a porous structure, and carbon and oxygen were the major constituents. RSM and ANN both predicted similar maximum turbidity removal under optimized conditions. This suggests that Manihot esculenta extract could be a suitable coagulant for the remediation of turbid wastewater.

Integrative metabolome and transcriptome analyses reveal the molecular mechanism underlying variation in floral scent during flower development of Chrysanthemum indicum var. aromaticum

Lu Zhu et al.

Summary: By analyzing the metabolome and transcriptome of Chrysanthemum indicum var. aromaticum (CIA) flowers at different developmental stages, this study identified 370 volatile metabolites, mainly terpenoids and esters, and 8,945 differentially expressed genes. Enrichment analysis revealed candidate genes associated with the biosynthesis of phenylpropanoids, esters, and terpenes. The study also found that the expression of volatile terpene-related genes was regulated by specific transcription factors. These findings provide insights into the molecular mechanisms of floral scent metabolite biosynthesis and offer valuable data for molecular breeding and utilization of CIA plants in the future.

Kinetic Modeling of Essential Oil Hydro-Distillation from Peels of Pomelo (Citrus grandis L.) Fruit Grown in Southern Vietnam

Tan Phat Dao et al.

Summary: Thorough understanding of kinetics is crucial for improving industrial processes. In this study, the kinetics of hydro-distillation process for producing essential oil from pomelo peels were modeled, with the simultaneous washing and diffusion model chosen as the most suitable for describing the extraction process. Experimental data showed that the washing stage occurs more rapidly than the diffusion stage.
