Table 1 Antioxidant activities of extracts as measured by DPPH and FRAP assays

Samples	DPPH IC50 (mg/mL)	FRAP μM TEAC/g DW
BHA	0.02 ± 0.002^a	2623.1 ± 13^a
Tocopherol	0.05 ± 0.0^b	NA
Catechin	NA	2302.8 ± 11.04^b
MCFE	0.9 ± 0.1^c	9.7 ± 0.1^c
MCE	3.2 ± 0.2^d	0.9 ± 0.3^d
CAE	3.7 ± 0.8^e	1.9 ± 0.1^e
Values with different letters are significantly different (p < 0.05) according to Duncan Test, SPSS version 16. All readings were taken in triplicate (n = 3). NA: Not Applicable; DW: Dry weight samples; MCFE: Morinda citrifolia fruit extract; MCE: Momordica charantia extract; CAE: Centella asiatica extract.

Morinda citrifolia	193 ± 40.1^a
Centella asiatica	84.5 ± 1.1^b
Values with different letters are significantly different (p < 0.05) according to Duncan test, SPSS version 16 (n = 2). DW: Dry weight of samples.

Figure 1 The inhibitory effect (%) of Epicatechin, Orlistat, MCE, MCFE, and CAE at a concentration of 0.25 mg/mL on PL activity. Values with different letters indicate a significant difference (p < 0.05), Duncan test, SPSS version16 (n = 3). MCFE: Morinda citrifolia fruit extract; MCE: Momordica charantia extract; CAE: Centella asiatica extract; PL: Pancreatic lipase.

Figure 2 The inhibitory effect (%) of Epicatechin, Orlistat, MCE, MCFE, and CAE at a concentration of 0.007 mg/mL on PL activity. Values with different letters indicate a significant difference (p < 0.05), Duncan test, SPSS version16 (n = 3). MCFE: Morinda citrifolia fruit extract; MCE: Momordica charantia extract; CAE: Centella asiatica extract; PL: Pancreatic lipase.

Figure 3 The inhibitory effects of MCE, MCFE, and CAE on PL activity at different concentrations. Values with different letters indicate a significant difference (p < 0.05), Duncan test, SPSS version16 (n = 3). MCFE: Morinda citrifolia fruit extract; MCE: Momordica charantia extract; CAE: Centella asiatica extract; PL: Pancreatic lipase.
