Research

Research articles related to Memecylon species:
Anti- oxidant activity: Different dry extracts of Memecylon umbellatum Burm leaf obtained by various solvents such as petroleum ether, chloroform, ethyl acetate, acetone, methanol and chloroform water (IP) was screened to reap the benefits of its antioxidant and free radical scavenging properties using ascorbic acid as standard antioxidants. Among the all extracts, Methanol leaf extract has showed higher Antioxidant activity (84.65 ± 0.064 %) having IC50 Value 11.81 ± 0.033 μg/ml at 20 μg/ml. While, IC50 value for ascorbic acid was found to be 8.91 ± 0.084 μg/ml. The results clearly indicate that Methanol leaf extract of Memecylon umbellatum is effective in free radical scavenging.

Anti- inflammatory action: The aim of the study was to determine the anti-inflammatory, analgesic and antioxidant activities of the leaves of Memecylon edule Roxb. Hexane, (Hex), ethyl acetate (EtOAc), methanol (MeOH) and 50% methanol (MeOH50) fractions of the dry leaves were tested in vitro for their interleukin-10 production; the most active fraction was further studied in vivo for its anti-inflammatory and analgesic activities using the ethylphenylpropiolate (EPP)-induced mouse ear edema and the writhing test with mice. The EtOAc showed the highest stimulation for interleukin-10 production. In the EPP test, this fraction was significantly active 30 min after topical application at all doses used (0.5, 1.0, 2.0mg/ear); after 4h and at 1.0mg/ear EtOAc was slightly less active (inhibition 47.8%) than the reference, indomethacin, at the same dose (62.4%). At 200mg/kg orally, the EtOAc caused a significant inhibition of the writhing response by 56.6% which was like indomethacin at 10mg/kg. EtOAc, MeOH and MeOH50 exhibited radical scavenging activity.

Wound healing action: The present study was aimed to evaluate the wound healing activity of alcoholic leaf extract of Memecylon umbellatum Burm (Melastomataceae). An alcoholic leaf extract of Memecylon umbellatum Burm was examined for its wound healing activity in the form of ointment (0.5, 1.0 and 2% w/w) in two types of wound models in rats the excision and the incision wound model. The extract ointments showed significant response (p<0.001) in both the wound models as comparable to those of a standard drug nitrofurazone (NFZ) ointment (0.2% w/w) in terms of wound contracting ability, wound closure time and tensile strength.

Anti- microbial action: The petroleum ether, chloroform and methanol extracts of Memecylon malabaricum leaves were tested for antimicrobial activity. Only methanol extract has shown activity against bacteria both Gram (+) and Gram (-), and fungi.

Memecylon umbellatum, commonly known as Ironwood’, Anjani (Tamil),’ (Malayalam) or Alli (Hindi), is a small tree found in India, the Andaman islands and the coastal region of the Deccan. It is also found in Sri Lanka, where it is called Blue MistKora-Kaha (Sinhala language) and Kurrikaya (Tamil). The leaves contain a yellow dye, a glucoside, which is used for dyeing the robes of Buddhist monks and for colouring reed mats.

Anti- diabetic action: The methanolic extract of Memecylon malabaricum leaves is subjected to antidiabetic activity using experimental model of alloxan induced diabetes. The results showed that the methanolic extract significantly decrease the raised blood glucose level, comparable to reference standard, gliclazide. The results of this study explicate justification of the use of this plant in the treatment of diabetes.
