| Summary: | Abstract Background Study of phytochemicals and pharmacological properties of bryophytes has been neglected for a long time because of the three main reasons i.e. (i) difficulty in collection in large amount for analysis; (ii) their availablility only in particular season and (iii) their restricted geographic distribution. So, the aim of this work was to propagate Lunularia cruciata under in vitro condition for comparing its pharmacological properties and phytocmecial constituents with naturally grown counterparts. Method Axenic culture of L. cruciata was established by propagating gemmae under in vitro condition. Appropriate culture conditions, media, and the effect of hormones on growth and development were studied. The phytochemical composition was determined by GC-MS analysis and pharmacological activity was evaluated by assessing the antioxidant and anti-diabetic activities. For the antioxidant activity ABTS+ [2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)], DPPH• (2,2-diphenyl-1-picrylhydrazyl) and metal chelating assays were done and for evaluation of the in vitro anti-diabetic activity α-glucosidase and α-amylase inhibitory activities were done. Result Growth of L. cruciata was recorded in half strength MS media. Benzylaminopurine (BAP: 2 mg/L) and 1-Naphtheleneacetic acid (NAA: 0.5 mg/L) were the successful hormonal combination. GC-MS analysis revealed the existence of nine key compounds in both in vitro and naturally grown L. cruciata. Result of antioxidant and anti-diabetic activity showed that in vitro grown L. cruciata has a more or less similar antioxidant and anti-diabetic activities as naturally grown ones. This result confirms the possibility of using in vitro grown plants in place of naturally grown plants for research and clinical purposes.
