Results showed that alkaloids are present mostly in abundant quantities in the vegetative plant organs. Thus, the active principle responsible for the plant's medicinal property is alkaloidal. Based on the reports that for this species investigated the tuberous root is utilized, the observation that alkaloids are the only metabolic product in abundant quantities found in the root supports this conclusion. In as much as there are no reports yet on alkaloids with antibacterial and antifungal action obtained from other Stephania species, this should be investigated in this particular specimen. It is also suggested that studies be done to establish the most effective but safe dosage and whether there are any side effects with prolonged usage. Since alkaloids and aldehydes are present in abundant quantities in the stem and leaf petioles, the potentials of these plant parts for medicinal purposes could also be looked into. Efforts should be done to collect the female plant, especially the reproductive structures, as these are considered of utmost importance in species identification. Until these parts are studied, the species of this specimen could never be established. Unfortunately, until the areas where the plant was originally found are considered danger-free for those who are interested, efforts toward proper collection of specimens could be hampered. (Author)

This study aimed to: (1)determine the various metabolic products present in the plant; and (2)identify the plant organ/tissues wherein the metabolic products are most predominant.
