Pearl grass extract, a standardized bioactive polar extract of the herbs of Hedyotis corymbosa, is preclinically proven to have an activity to osteoarthritis and rheumatoid arthritis properties in an animal model. The current clinical study has evaluated the efficacy and safety of Pearl grass extract of osteoarthritis subjects. This research was a pilot study of osteoarthritis subjects using Parallel double-blind study design. Subjects have normal renal and liver function, above 50 years of age, and has a sign and symptoms of osteoarthritis included in the study. In the treatment, Pearl grass capsules were given as one capsule once daily for eight weeks, throughout the study, the weekly assessment to evaluate the adverse event. Thirty subjects of mean age 55.90 {\textpm} 3.7 years were evaluable. Pearl grass extract capsules did not change renal and liver function in 56 days treatment. Pearl grass capsule markedly reduced the consumption of analgesic drug compared with placebo groups. Pearl grass capsules also decreased pain scale better compare with placebo.

Introduction: Peperomia pellucida L. Kunth has been reported to have some biological activities such as antihypertensive and antioxidants. Herbal materials susceptible to contamination during processing and storage which can shortens their shelf life. Gamma-irradiation has been used as a method for preservation. Methods: This research aimed to analyze the effect of gamma-irradiation on inhibition activity of angiotensin converting enzyme (ACE), antioxidant activity, total phenol content, total flavonoid, and thin layer chromatography profiles of P. pellucida L. Herbs extract. The extract was irradiated with 60Co gamma rays at 2.5; 5; 7.5; dan 10 kGy. Results: Irradiation up to 10 kGy did not change ACE inhibitory activity and TLC profile. No significant differences were noted in the inhibition activity of ACE and the type of chromatogram profiles between non-irradiated extract and irradiated extracts up to a dose of 10 kGy while total flavonoids showed a significant decrease. In addition, total phenolic content and antioxidant activity showed a significant increase of extracts were irradiated up to 5 kGy and decrease at dose 7,5 kGy and 10 kGy. Gamma-irradiation up to 10 kGy didn\’t affect the activity of ACEinhibitor in-vitro while significant difference (P \<0.05) of antioxidant activity, total flavonoids and phenolic content of the extract P. Pellucida. Conclusion: In conclusion, gamma - irradiation can be used as a preservation method for ethanol extract P. Pellucida L. Kunth herbs.
