“…Hence, in the case of Vitex , we can use micro-propagated plants as a potent source of phyto-compounds for commercialization without destroying the wild plant population[ 27 , 28 ]. A recent literature review showed that plant biomass with good amounts of methyl palmitate (a chemically modified derivative of hexadecanoic acid) is used in biodiesel production[ 29 , 30 ]. The findings of the present study showed that in-vitro grown callus is a good medium for the synthesis of methyl esters.…”

BACKGROUND The investigation of plant-based therapeutic agents in medicinal plants has revealed their presence in the extracts and provides the vision to formulate novel techniques for drug therapy. Vitex negundo (V. negundo ), a perennial herb belonging to the Varbanaceae family, is extensively used in conventional medication. AIM To determine the existence of therapeutic components in leaf and callus extracts from wild V. negundo plants using gas chromatography-mass spectrometry (GC-MS). METHODS In this study, we conducted GC-MS on wild plant leaf extracts and correlated the presence of constituents with those in callus extracts. Various growth regulators such as 6-benzylaminopurine (BAP), 2,4-dichlorophenoxyacetic acid (2,4-D), α-naphthylacetic acid (NAA), and di-phenylurea (DPU) were added to plant leaves and in-vitro callus and grown on MS medium. RESULTS The results clearly indicated that the addition of BAP (2.0 mg/L), 2,4-D (0.2 mg/mL), DPU (2.0 mg/L) and 2,4-D (0.2 mg/mL) in MS medium resulted in rapid callus development. The plant profile of Vitex extracts by GC-MS analysis showed that 24, 10, and 14 bioactive constituents were detected in the methanolic extract of leaf, green callus and the methanolic extract of white loose callus, respectively. CONCLUSION Octadecadienoic acid, hexadecanoic acid and methyl ester were the major constituents in the leaf and callus methanolic extract. Octadecadienoic acid was the most common constituent in all samples. The maximum concentration of octadecadienoic acid in leaves, green callus and white loose callus was 21.93%, 47.79% and 40.38%, respectively. These findings demonstrate that the concentration of octadecadienoic acid doubles in-vitro compared to in-vivo . In addition to octadecadienoic acid; butyric acid, benzene, 1-methoxy-4-(1-propenyl), dospan, tridecanedialdehyde, methylcyclohexenylbutanol, chlorpyrifos, n-secondary terpene diester, anflunine and other important active compounds were also detected. All these components were only available in callus formed in-vitro . This study showed that the callus contained additional botanical characteristics compared with wild plants. Due to the presence of numerous bioactive compounds, the medical use of Vitex for various diseases has been accepted and the plant is considered an important source of therapeutics for research and development.

“…These fatty acid derivatives are produced from parent acids (palmitic, linoleic, and oleic acid) reacting with methanol via biological esterification (2). And because each of these fatty acid derivatives is characterized by unique features discernible in its mass spectrometry profiles, they may be used as an analytical reference standard for the quantification of the analyte in biodiesel samples using chromatography techniques [46]. However, the differences in structure and composition of these parent acids lead to expected variations in the mass spectra depicted in Figures 3 and 4…”

Currently, there exists a significant need for alternate sources of petroleum fuel due to escalating environmental challenges and diminishing global oil reserves. Biodiesel, an environmentally friendly and sustainable fuel, is one of the most adaptable alternatives to petroleum fuel. This study’s goals were to get biodiesel from three oils (olive, palm, and jojoba) and see how well lipases work as biocatalysts for the esterification process. The production of biodiesel was obtained from two fungal strains, Aspergillus niger MH079049.1 and A. niger MH078571.1, and four distinct fatty acids and four organic solvents were used. The study determined the optimal reaction conditions to be a reaction time of 24 h, an enzyme concentration of 3 mL, and an oil-to-methanol ratio of 3:1. This study showed that lipase works well in making biodiesel, with an impressive esterification yield of 99%, and the highest level of productivity was attained when olive oil and jojoba oils were subjected to an incubation time of 18 h and 22 h, respectively, in the presence of palm oil.
