The terrestrial Ludisia discolor, also referred to as the jewel orchid is prized for
the quality of its leaves. L. discolor is known as a medicinal herb and is touted for its heatand
pathogen-resisting qualities. L. discolor is valuable in the production of both flavonoids
and anthocyanins, antioxidants that are exalted in the health industry. Plant cell cultures
have emerged as alternative sources of anthocyanin production. Plant protoplast cultures
are used frequently in transient gene expression studies and in the establishment of callus
and cell suspension cultures. Benefits of plant protoplast system include similarity to cells
found in plant tissues, reproduction under controlled conditions, and prevention of masking
of stress responses to previous handling techniques. A study was conducted to assess the
amenability of the stem and leaves of L. discolor to protoplast isolation. The stem and leaf
segments were weighed, sliced into thin layers, immersed in a digestion medium, washed
and then cultured onto a recovery medium. Results indicated that the production of plant
protoplasts from L. discolor may be viewed as an alternative in the generation of cell
cultures and ultimately in the production of anthocyanins from the cell cultures.
