Cancer is a disease characterized by uncontrolled cell growth and the ability of these cells to attack biological tissue. Various attempts have been made, one of them with treatment to kill cancer cells, but not a few of these efforts actually cause side effects. This fact demands the need for a safe alternative way to treat cancer using natural ingredients. One of the local natural resources that has the potential to treat cancer is Majapahit (Crescentia cujete). In this study, Majapahit (C. cujete) stem extracts were carried out which have anticancer activity. The first stage was screening by conducting a qualitative analysis of the ethanol extract of the stem of the majapahit plant (C. cujete). Furthermore, a toxicity test was carried out against Artemia salina Leach using the Brine Shrimp Lethality Test (BST) method. Phytochemical testing was carried out to check the content of secondary metabolite compounds contained in the majapahit stem extract, and the results were positive for flavonoids, tannins, saponins and phenolics. This data, supported by spectrophotometric tests, proved that the largest concentration of the ethanolic extract of the majapahit (C. cujete) stem was 24.05% tannin. Then the LC50 test from the toxicity test of the active component of majapahit plant stem extract (C. cujete) against Artemia salina Leach showed a concentration of 0.01 µg / mL and 0.04 µg / mL, namely with a percentage below 50%.

  This study focused to develop the fingerprint profile of Phyllanthus niruri through high performance thin layer chromatography. Various solvent extracts such as ethanol and water were prepared and phytochemical screening was made using standard procedures. The preliminary phytochemical analysis of two extracts of the plant showed the presence of secondary metabolites viz., alkaloids, triterpenoids, proteins, amino acids, flavonoids and steroids. The total flavonoid contents of leaves were significantly higher than those revealed in stem and root. The total phenolic contents of Phyllanthus niruri leaves (aqueous extract), leaves (ethanol extract) and root (ethanol extract) were 5.71 mg GAE/100 mg extract, 7.66 mg GAE/100 mg and 5.63 mg GAE/100 mg extract respectively. Methanol extract of Phyllanthus niruri was subjected to HPTLC analysis due to it is most effective, highly polar universal solvent for extraction of phytoconstituents. Among the samples, leaves extract resolved maximum number of spots followed by stem extract and root extract. It can be concluded that HPTLC fingerprinting of Phyllanthus niruri may be useful in differentiating the species from the adulterant and authentication of this herbal plant in the medical field and systematic plant studies.

Abstract. Awaludin, Kartina, Maulianawati D, Manalu W, Andriyanto, Septiana R, Arfandi A, Lalang Y. 2020. Short Communication: Phytochemical screening and toxicity of ethanol extract of Sauropus androgynus. Biodiversitas 21: 2966-2970. Katuk (Sauropus androgynus L.) (SAL) is a plant used to increase the production of breast milk for nursing mothers and lactating mammalian animals because this plant contains high sterols. Phytosterols are plant sterols known to play a role in the synthesis and secretion of progesterone and estradiol.  Progesterone and estradiol are hormones that are involved in controlling the reproduction and mammary gland growth and development in mammalian animals. Estradiol also stimulates vitellogenin synthesis in oviparous animals such as avian and fish.  The study was designed to determine the phytochemical contents and the level of toxicity of the SAL ethanol extract. The research was conducted in 4 phases i.e., (i) extraction of SAL samples using ethanol 70%, (ii) the analysis of phytochemical content of SAL extract using GCMS, (iii) toxicity test of SAL extract in giant tiger shrimp larvae, and (iv) data analysis. The results of GCMS analysis showed that the SAL extract was dominated by the fatty acid group (62.92%), phenol (15.3%), and terpenoids (4.03%). These compounds have roles in animal reproduction and production. The mortality data of giant tiger shrimp larvae were analyzed using probit analysis to determine the LC50 of ethanol extract of SAL. The results of toxicity test for 24 hours showed that the LC50 of the ethanol extract of SAL was 552.208 mg/L. The phytochemical analysis showed that SAL extract has dominant concentrations of fatty acid, phenol, and terpenoid that could be used to improve the reproduction and production of fish.
