Ethnopharmacological relevance Temu giring, the rhizome of Curcuma heyneana Valeton & Zipj ( C. heyneana ), is native to tropical regions, especially in Indonesia. It is traditionally used as a skin care, for cosmetic and body freshness, in Javanese and Balinese women, and has many other bioactivities such as antioxidant, anticancer and antiinflammatory. Aim of the study The purpose of this study was to determine the antiaging activity of C. heyneana to prove its traditional use. Materials and methods The antioxidant activity was determined using the DPPH free radical method, and anti-aging activity was examined using in vitro assays such as tyrosinase inhibitor and collagenase inhibitor. In vivo tests were performed by observing histomorphologic changes in rat skin exposed to Ultraviolet (UV) rays. The total curcuminoid contents and chromatographic profiles were determined by Thin Layer Chromatography (TLC) – densitometry. Results In all in vitro assays, all of the extracts showed a dose-dependent manner in the final concentration range from 62.5 to 500 µg/mL for DPPH assay and 31.25 to 250 µg/mL for tyrosinase inhibition and collagenase inhibition assay. Curcuminoid (CUR), the active principle of Curcuma genus shows antioxidant, tyrosinase inhibitor and collagenase inhibitor activity greater than all C. heyneana extracts. The in vivo assay results showed that the topical application of the crude extract of C. heyneana produced significant improvement effects on the UV-induced skin structure damage. The total CUR content was correlated with the anti-aging activity of Curcuma heyneana . Conclusions The results show that C. heyneana contains antioxidant compounds and has potent anti-aging activity, indicating that it can be used as an anti-aging drug candidate or as a phyto-cosmeceutical.

Ethnopharmacology Relevance: Graptophyllum pictum (L.) Griff., known as "handeuleum" in West Java and "Daun Ungu" in Indonesia, is traditionally used to cure hemorrhoids., Aim of the Study: The purpose of this study is to prove its effectiveness scientifically using anorectal histological parameters in Croton oil-induced hemorrhoid mice., Materials and Methods: In vivo tests were performed by observing histomorphologic changes in mice anorectal tissue induced by croton oil. In addition, in vitro assay was performed for evaluating antioxidant activity, astringency property, and hemostasis-associated activity. The antioxidant activity was measured using a DPPH radical scavenging assay. The total flavonoid and phenolic contents were also determined spectrophotometrically., Results: The in vivo assay showed that the oral-topical combination use of the ethanolic extract of G. pictum leaves demonstrated significant improvement on the croton oil-induced anorectal damage better than the single application by oral or topical application., Conclusion: These results showed that G. pictum has potent anti hemorrhoid activity, especially for the combinational use of oral and topical administration., (Copyright © 2021 Elsevier B.V.

Two new bisindole alkaloids, biscarpamontamine A (1), possessing an aspidosperma-iboga-type skeleton, and biscarpamontamine B (2), having an aspidosperma-aspidosperma-type skeleton, were isolated from stems of Tabernaemontana sphaerocarpa, and their structures were elucidated on the basis of spectroscopic data analysis. The absolute configuration of biscarpamontamine B (2) was established by comparison of its CD spectrum and with that of vobtusine (3). Biscarpamontamine B (2) showed potent cytotoxicity against various human cancer cell lines.
