Flavonoid Compounds From The Leaves Of Kalanchoe Tomentosa And Their Cytotoxic Activity Against P-388 Murine Leukemia Cell

Kalanchoe plant, known as “sosor bebek” in Indonesia is a perennial herb and has succulent leaves. The plant is known in folklore and traditional medicine in Indonesia for the treatment of fever, abscesses, bruises, contused wounds, coughs and skin diseases. During the course of our continuing search for novel cytotoxic compounds, the methanolic extract  of Kalanchoe tomentosa plants showed cytotoxic activity against P-388 murine leukemia cells. The methanolic extract of the fresh  leaves of  K. tomentosa was concentrated and extracted successively with n-hexane, ethyl acetate and n-butanol. The ethyl acetate extract exhibited strongest cytotoxic activity againts P-388 murine leukemia cells. By using the cytotoxic activity to follow the separation, the ethyl acetate fraction was separated by combination of column chromatography on silica gel and preparative TLC on silica gel GF254 to afford a kaempferol-3-O-glycosides (1) and kaempferol-3-O-rhamnoside (2). Compound 1 and 2 showed cytotoxic activity against P-388 murine leukemia cells with IC50 > 100μg/mL and IC50 3.32 μg / m

An Introduction to Indonesian Wild Shiitake

Pegler suggested that shiitake comprises three morphological species: Lentinula edodes (continental and northeast Asia), L. lateritia (tropical Asia and Australasia), and L. novae-zelandiae (New Zealand). The current study reported for the first time the occurrence of L. lateritia (Berk.) Pegler in Indonesia. During a fungus foray in Kerinci (Jambi, Sumatra, Indonesia) in 2022 and 2023 by the Indonesian mushroom hunter community, some basidiomata of Lentinula were obtained. At a glance, our specimens resembled L. edodes. The current study aims to justify the taxonomical position of our specimens based on morphological and molecular data. The fresh basidiomata were used for morphological and molecular analyses. The molecular work was done using ITS 4/5 Primers for phylogenetic analysis of rDNA-ITS region. Morphologically, the uniformly reddish brown, smooth, and glabrous of pileus confirmed our specimens as L. lateritia. In addition, the absence of a range of colors and squamules pileus distinguished L. lateritia BO24628 form L. edodes, while the formation of florets cheilocystidia in L. madagasikarensis was the distinctive character of our specimens. The BLAST result revealed that our specimen has high similarity (99-100%) with L. lateritia and L. edodes as the top hits. The phylogenetic tree (RAxML) nested our specimens in the L. lateria clade and is closely related to one specimen from Papua New Guenia (PNG) (BS 98%). In addition, L. lateritia BO24628 has a sister clade of the specimen from PNG and Australia. Moreover, we provide the herbarium collection of wild L. lateritia in Indonesia
