The Efficient and Easy Micropropagation Protocol of <i>Phyllanthus niruri</i>

<i>Phyllanthus niruri </i>(<i>P. niruri</i>) or Dukung Anak is a herbal plant in the Phyllanthaceae family that has been used traditionally to treat various ailments such as diabetes, jaundice, flu and cough. <i>P. niruri </i>contains numerous medicinal benefits such as anti-tumor and anti-carcinogenic properties and a remedy for hepatitis B viral infection. Due to its beneficial properties, <i>P. niruri </i>is overharvested and wild plants become scarce. This study was conducted to develop an appropriate in vitro culture protocol for the mass production of <i>P. niruri</i>. An aseptic culture of <i>P. niruri</i> was established followed by multiplication of explants using different types of basal medium and its strength and plant growth regulators manipulation. This study also established the induction of in vitro rooting utilizing various types and concentrations of auxin. Treatment of Clorox^® with 30% concentration showed the lowest percentage (%) of contamination, 4.44% in <i>P. niruri </i>culture. Nodal segments of <i>P. niruri</i> were successfully induced in full-strength of Murashige and Skoog (MS) basal media with 2.33 number of shoots, 3.11 cm length of shoot and 27.91 number of leaves. In addition, explants in full-strength MS media without any additional cytokinin were recorded as the optimum results for all parameters including the number of shoots (5.0 shoots), the length of shoots (3.68 cm) and the number of leaves (27.33 leaves). Treatment of 2.5 µM indole-3-butyric acid (IBA) showed the highest number of roots (17.92 roots) and root length (1.29 cm). Rooted explants were transferred for acclimatization, and the plantlet showed over 80% of survival rate. In conclusion, plantlets of <i>P. niruri</i> were successfully induced and multiplied via in vitro culture, which could be a step closer to its commercialization.
