In Vitro Calli Production Resulted in Different Profiles of Plant-Derived Medicinal Compounds in Phyllanthus amarus

The efficient production of plant-derived medicinal compounds (PDMCs) from in vitro plants requires improvements in knowledge about control of plant or organ development and factors affecting the biosynthesis pathway of specific PDMCs under in vitro conditions, leading to a realistic large-scale tool for in vitro secondary metabolite production. Thus, this study aimed to develop an in vitro technique, through the induction and proliferation of calli, for production of plant fresh weight, and to compare the PDMC profile obtained from the plants versus in vitro calli of Phyllanthus amarus. It was successfully possible to obtain and proliferate two types of calli, one with a beige color and a friable appearance, obtained in the dark using Murashige and Skoog (MS) medium plus 2,4-dichlorophenoxyacetic acid (2,4-D), and a second type with a green color, rigid consistency, and nonfriable appearance obtained under light conditions and MS medium plus 6-benzyladenine (6-BA). In vitro micropropagated plants that gave rise to calli were also acclimatized in a greenhouse and cultivated until obtaining the mass for PDMC analysis and used as a control. While the micropropagated-derived plants concentrated the lignans niranthin, nirtetralin, and phyllanthin, the Phyllanthus amarus calli proliferated in vitro concentrated a completely different biochemical profile and synthesis of compounds, such as betulone, squalene, stigmasterol, and β-sitosterol, in addition to others not identified by GC-MS database. These results demonstrate the possibility of applying the calli in vitro from Phyllanthus amarus for production of important PDMCs unlike those obtained in cultures of differentiated tissues from field plants.

“…Traditional cultivation of Phyllanthus species for medicinal purposes is carried out under field or greenhouse conditions, but is hindered by the low production of secondary metabolites of interest, such as lignans, as well as the natural dormancy of seeds, which limits its propagation aimed at large-scale cultivation [ 6 ].…”

“…The agronomic management in the production of phytopharmaceuticals, besides being important in the production of biomass and the active principles in medicinal plants, is also an efficient alternative to reach the quality, quantity and safety of these products for the consumers (Maia-Almeida et al, 2011;Santos et al,. 2012).…”

“…2012). Agricultural practices such as changes in plant densities and the use of mulch may alter the biomass production and active compounds of these species (Araújo et al, 2009;Maia-Almeida et al, 2011). Thus, the objective of this study was to evaluate the influence of spacing and plant cover on biomass production, chemical composition and production of essential oil of tropical black sage.…”

A B S T R A C TThe objective of this study was to evaluate the influence of spacing and mulch on biomass production, chemical composition and production of essential oil of tropical black sage. A randomized block design was used in a 2×2 factorial scheme: two spacings (1.6 × 0.5 m and 1.0 × 0.5 m), with and without mulch, using five replications. In the end, the combination of spacing and presence and absence of mulch did not influence the height and diameter of the stem. However, it has influenced fresh matter: 8765.00 kg ha-1 (1.0 × 0.5 m, with mulch) and 6112.50 kg ha-1 (1.6 × 0.5 m, without mulch). The spacing 1.0 x 0.5 m was what provided higher dry matter (3052.14 kg ha-1). For the production of essential oil, the combination of spacing of 1.0 × 0.5 m, with mulch provided greater production (484.50 kg ha-1). Twenty-seven compounds were detected, of which 23 were identified, most of which were sesquiterpenes and monoterpenes. The α-pinene and the β-caryophyllene showed higher abundances in all samples, regardless of the treatment. The contents of α-humulene was sufficient to meet the requirements of the pharmaceutical industry. Thus, the alteration in soil spacing and mulch influences the production of essential oil and biomass, but it does not influence the relatives amount of the α-humulene and of the β-caryophyllene. Keywords:Varronia curassavica Jacq., α-humulene, β-caryophyllene, mulch, spacing. R E S U M OO objetivo deste estudo foi avaliar a influência do espaçamento e da cobertura morta sobre a produção da biomassa, composição química e produção do óleo essencial de erva-baleeira. Utilizou-se o delineamento de blocos casualizados, em esquema fatorial 2×2: dois espaçamentos (1.6 × 0.5 m e 1.0 × 0.5 m), com e sem cobertura morta, sendo utilizadas cinco repetições. Ao final, a combinação entre espaçamento e presença e ausência de cobertura não influenciaram na altura e diâmetro do caule. No entanto, influenciou na matéria fresca: 8765.00 kg ha-1 (1.0 × 0.5 m, com cobertura) e 6112.50 kg ha-1 (1.6 × 0.5 m, sem cobertura). O espaçamento 1.0 × 0.5 m foi o que proporcionou maior matéria seca (3052.14 kg ha-1). Para a produção de óleo essencial, a combinação do espaçamento de 1.0 × 0.5 m, com cobertura proporcionou maior produção (484.50 kg ha-1). Foram detectados 27 compostos dos quais 23 foram identificados, sendo a maior parte sesquiterpenos e monoterpenos. O α-pineno e o β-cariofileno apresentaram maiores abundâncias em todas as amostras, independente do tratamento. Em todos os tratamentos, o teor de α-humuleno foi suficiente para atender às exigências da indústria farmacêutica. Assim a alteração no espaçamento e na cobertura do solo influencia na produção do óleo essencial, e da biomassa, porém não influencia nos teores do α-humuleno e do β-cariofileno. Palavras-chave:Varronia curassavica Jacq., α-humuleno, β-cariofileno, cobertura vegetal, espaçamento.
