Abstract

Background and objective Harpullia pendula Planch leaves belong to the Sapindaceae family. The study aimed to investigate the phenolic constituents and evaluate the antioxidant and α-amylase inhibitory activities of the plant’s extracts and its major compounds.Materials and methods The compounds were isolated through chromatographic techniques from the defatted ethanolic extract (DAEE). Their structures were determined by ultraviolet, mass spectrometer, and nuclear magnetic resonance spectroscopy.Results The flavonoids kaempferol 3-O-(6″galloyl)- apiofuranosyl (1‴→2″)-β-galactopyranoside, kaempferol-3-O-β-glucopyranosyl(1‴→6″)-β-glucopyranoside, kaempferol 3-O-(6″galloyl)-apiofuranosyl (1‴→2″)-β-galactopyranoside, rutin, vitexin, isovitexin, orientin, quercetin, kaempferol; the tannins ellagic acid, gallic acid, methyl gallate, 2,6-di-O-galloyl(α/β)glucoside, 2,3-di-O-galloyl(α/β)glucoside, and tetragalloyl glucoside in addition to two benzene acetic acid derivatives, harpulliaside A and cavaol B, were isolated from the total bioactive ethanolic extract (TEE). The TEE and the DAEE of H. pendula have a total phenolic content of 255.5±7.18 and 222.9±6.43 mg gallic acid equivalents/g extract, respectively, and a total flavonoid content of 111.6±3.2 and 102.6±2.6 mg quercetin equivalents/g extract, respectively. With respect to the in vitro study, DAEE, TEE, and methyl gallate showed an interesting inhibitory activity on 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
