Background and Aim: Cancer is one of the leading causes of death, the need for new anticancer herbal drugs is becoming more urgent considering the side effects of synthetic drugs. This study aimed to determine the anticancer activity of isolates derived from the methanol extract of Annona squamosa Linn. leaves and to identify the compounds that have an active effect against HeLa cells. Materials and Methods: The leaf metabolites of A. squamosa L. were extracted using methanol at room temperature (28°C) and were partitioned into n-hexane, chloroform, and n-butanol. The toxicity test of these extracts was conducted using a brine shrimp lethality assay. Furthermore, the most toxic extracts were separated and purified using silica gel column chromatography to yield four isolate fractions: FA, FB, FC, and FD. The most toxic isolates were tested for anticancer against HeLa cells, and their compounds were identified using liquid chromatography-mass spectrometry. Results: The results showed that the most toxic isolate with an LC50 value of 100.00 ppm had a potency similar to that of an anticancer agent with an IC50 value of 70.9021 ppm. Furthermore, the five compounds identified in this isolate include (6S, 7aR)-6-hydroxy-4,4,7a-trimethyl-6,7-dihydro-5H-1-benzofuran-2-one or loliolide, cocamidopropyl betaine, N-[3- (dimethylamino)propyl]dodecanamide or lauramidopropyl dimethylamine, linolenic acid, and 1-dodecyl-2-azepanone or laurocapram. Conclusion: It can be concluded that the leaf isolates of A. squamosa Linn. had shown anticancer activities against cervical cancer.

Introduction: The ethanol extract of the jamblang fruit seed (Syzygium cumini L.) is known to have an antidiabetic effect and this is further confirmed by the high intensity of its α-amylase inhibitory effect. Aim: The purpose of this study was to determine the antidiabetic activity of jamblang fruit seed extract in reducing blood sugar levels. Method: Phytochemical screening was carried out on the ethanol extract from jamblang fruit seeds. Twenty-eight male wistar rats were given alloxan to induce diabetes. The rats were divided into four groups: normal control, negative control (CMC-Na), positive control (Glibenclamide), and a group that was given ethanol extract of jamblang seeds. Measurement of blood glucose levels was carried out on day 0 and day 15. Results: The phytochemical screening results show that the ethanolic extract of jamblang fruit seeds (Syzygium cumini L.) contains alkaloids, flavonoids, saponins, tannins, and polyphenols, as well as steroids and triterpenoids. The group being treated with ethanol extract from jamblang seeds showed decreased blood sugar levels on day 15, indicating the antidiabetic effectiveness of the extract. Conclusion: Ethanol extract from jamblang seeds (Syzygium cumini) contains alkaloids, flavonoids, saponins, tannins, polyphenols, steroids, and triterpenoids; and is able to reduce blood glucose levels of male wistar rats induced with alloxan.
