<strong><em>Flavanoid, steroid, and terpenoid contents of 20 Manokwari medicinal plants were analyzed.  The antioxidant activity, total phenolic contents and antitumor activity of 20 Manokwari medicinal plants were also evaluated. The result shows that 83% positif to flavanoid test, 59% positif to terpenoid test and only 25% positif steroid. Antioxidant activity and total phenolic contents evaluated using Ferric Thiocianate (FTC) and Folin-Ciocalteu methods respectively. Antioxidant activity and total phenolic contents of medicinal plants were extracted by the traditional method, boiling in water and also in 80% methanol. Twenty plants evaluated in both exstracts have significantly varies of antioxidant activities and phenolic contents,  A significant and linier correlation coefficient between the antioxidant activity and the total phenolic content was found in both aqueous (R<sup>2</sup>= 0,77) and methanol (R<sup>2</sup> = 0,85). Antitumor activity was tested using cell maurine P-388 and only 2 of medicinal plants are active to inhibit cell maurine P-388. Comparing extraction efficiency of the two methods, the methanol extracted phenolic compounds more efficiently, and antioxidant activity of the extract was higher.</em></strong>

Objective: The present study deals with the antioxidant assays of the different leaf extracts of two medicinal plants, Sphaeranthus indicus and Psophocarpus tetragonolobus. Methods: Dried leaves of S. indicus and P. tetragonolobus were packed in separate round bottom flasks for sample extraction using ethanol, methanol, hexane, and distilled water as solvents for 72 h, and the extracts were collected after evaporating the solvents. Antioxidant studies of the various extracts were performed by 1-diphenyl-2-picrylhydrazyl and Ferric Reducing Ability of Plasma assays.Results: Among the two plants studied, S. indicus showed better 2-diphenyl-1-picryl-hydrazyl (DPPH), scavenging activity than P. tetragonolobus with IC50 values of 174.380 and 262.313, respectively, as compared to that of the standard, ascorbic acid, IC50 value of which being 111.16. The FRAP assay results for both the plants indicated that the methanol fractions showed closer results when compared with standards, ascorbic acid and quercetin. The IC50 value of S. indicus, P tetragonolobus, ascorbic acid, and quercetin was 70.065, 151.953, 85.162, and 79.647, respectively. These results clearly indicate that S. indicus methanol fraction had better antioxidant activity when compared to both standards.Conclusion: It is concluded that S. indicus and P. tetragonolobus have excellent antioxidant activities which could be the major contributing factors for their medicinal roles. Further studies in this direction are being carried on.

The roots of Iostephane heterophylla are popular in Mexican traditional medicine and as such are a good candidate to develop herbal drug preparations to be used as phytomedicine. International criteria for validation and standardization of a herbal product as phytomedicine include, among others, the integration of microscopic and histochemical characteristics of the raw material, as in this case the herbal drug, to guarantee its authenticity. As an original contribution to the knowledge of the root structure of this species, fresh roots fixed in FAA, were processed with conventional histological techniques (paraffin embedment and subsequent transversal and longitudinal sections that were stained with safranin-fast green) and stained with histochemical markers for identification of cellular contents. The root description includes dermic, fundamental and vascular tissues as well as cellular contents (proteins, polysaccharides, polyphenols, condensed and hydrolyzed tannins, starches and lipids, some of which have been isolated in previous phytochemical studies). These characteristics are compared to those of other species of Asteraceae as an initial comparative study to contribute to identify medicinal plants based upon their underground parts.
