Curcuma longa, Curcuma xanthorrhiza, and Curcuma manga have been widely used for herbal or traditional medicine purposes. It was reported that turmeric plants provided several biological activities such as antioxidant, anti-inflammatory, hepatoprotector, cardioprotector, and anticancer activities. Authentication of the Curcuma species is important to ensure its authenticity and to avoid adulteration practices. Plants from different origins will have different metabolite compositions because metabolites are affected by soil nutrition, climate, temperature, and humidity. 1H-NMR spectroscopy, principal component analysis (PCA), and orthogonal projections to latent structures-discriminant analysis (OPLS-DA) were used for authentication of C. longa, C. xanthorrhiza, and C. manga from seven different origins in Indonesia. From the 1H-NMR analysis it was obtained that 14 metabolites were responsible for generating classification model such as curcumin, demethoxycurcumin, alanine, methionine, threonine, lysine, alpha-glucose, beta-glucose, sucrose, alpha-fructose, beta-fructose, fumaric acid, tyrosine, and formate. Both PCA and OPLS-DA model demonstrated goodness of fit (R2 value more than 0.8) and good predictivity (Q2 value more than 0.45). All OPLS-DA models were validated by assessing the permutation test results with high value of original R2 and Q2. It can be concluded that metabolite fingerprinting using 1H-NMR spectroscopy and chemometrics provide a powerful tool for authentication of herbal and medicinal plants.

Herbal medicines (HMs) are regarded as one of the traditional medicines in health care to prevent and treat some diseases. Some herbal components such as turmeric and ginger are used as HMs, therefore the identification and confirmation of herbal use are very necessary. In addition, the adulteration practice, mainly motivated to gain economical profits, may occur by substituting the high price of HMs with lower-priced ones or by addition of certain chemical constituents known as Bahan Kimia Obat (chemical drug ingredients) in Indonesia. Some analytical methods based on spectroscopic and chromatographic methods are developed for the authenticity and confirmation of the HMs used. Some approaches are explored during HMs authentication including single-component analysis, fingerprinting profiles, and metabolomics studies. The absence of reference standards for certain chemical markers has led to exploring the fingerprinting approach as a tool for the authentication of HMs. During fingerprinting-based spectroscopic and chromatographic methods, the data obtained were big, therefore the use of chemometrics is a must. This review highlights the application of fingerprinting profiles using variables of spectral and chromatogram data for authentication in HMs. Indeed, some chemometrics techniques, mainly pattern recognition either unsupervised or supervised, were applied for this purpose.

Co-administered medicinal herbs can modify a drug’s pharmacokinetics (PK), effectiveness, and toxicity. Andrographis paniculata (Burm. f.) ethanolic extract (APE) and andrographolide (AND) (a potent CYP2C9 inducer/inhibitor) can alter the pharmacokinetic parameters of glipizide (GLZ). This study aimed to determine the potential pharmacokinetics of herb–drug interactions between GLZ and APE/AND in the plasma of normal and diabetic rats using the HPLC bioanalysis method. The glipizide bioanalytical method established with RP-HPLC/UV instrument was validated following the EMA guidelines. GLZ was administered alone and in combination with APE or AND to normal and diabetic rats. The GLZ pharmacokinetic parameters were estimated according to the correlation between concentration and sampling time using the PK solver program. A simple and rapid GLZ bioanalysis technique with a lower limit of quantitation of 25 ng/mL was developed and presented the following parameters: accuracy (error ≤ 15%), precision (CV ≤ 15%), selectivity, stability, and linearity (R2 = 0.998) at concentrations ranging 25–1500 ng/mL. APE administration significantly improved the Cmax and AUC0–t/AUC0–∞ GLZ values in normal and diabetic rats (p < 0.05). AND significantly reduced the bioavailability of GLZ in diabetic rats with small values of T 1/2, Cmax, and AUC0–t/AUC0–∞ (p < 0.05). This combination can be considered in administering medications because it can influence the pharmacological effects of GLZ.

Our previous study showed that water-soluble fiber from bengkoang (Pachyrizus erosus (L.) Urban) fiber extract (BFE) and bengkoang fiber fraction B (BFE-B) have phagocytic activity and modulation of cytokine production in vitro. The present study evaluates the immunomodulatory effects of water-soluble fibers BFE and BFE-B on male mice induced by hepatitis B vaccine. Thirty mice were divided into six groups and induced by hepatitis B vaccine intraperitoneally on days 7 and 14. The mice were then treated with BFE, BFE-B, levamisole, or sodium carboxymethyl cellulose for 18 days. At the end of the treatments (day 19), phagocytic activity, lymphocyte proliferation, spleen index, cytokine, and immunoglobulin G (IgG) production were determined. The results showed that the water-soluble fiber treatment could significantly increase phagocytic capacity, nitric oxide production, and spleen index. However, BFE-B could modulate tumor necrosis factor (TNF)-α and interleukin (IL)-10 secretion, BFE demonstrated no such effect on cytokine production. Lymphocyte proliferation assay revealed that treatment with 50 mg/kg body weight (BW) BFE and 50 mg/kg BW BFE-B could significantly enhance lymphocyte proliferation. Treatment with 25 and 50 mg/kg BW BFE-B stimulated IgG production. In conclusion, BFE and BFE-B similarly have immunomodulatory effects on innate immune responses. BFE-B further demonstrated immunomodulatory effects on adaptive immune responses.

The histological testing showed that ASNE could regenerate pancreatic beta cells. [...]ASNE ameliorated pancreatic beta cells. [...]the initial symptom in the pathogenesis of diabetes is a decrease in the beta-cell function, which plays a role in causing type-2 diabetes mellitus (T2DM). [...]it is necessary to restore cell functions to prevent T2DM.5 Self-nanoemulsifying (SNE) is a method to improve the solubility and bioavailability of drugs, such as AND,1 lovastatin,6 nisoldipine,7 and glipizide.8 SNE has also been reported to be able to increase the anti-cancer activity of genistein9 and the antifungal activity of orally administered nystatin.10 Compared with the natural forms, solid SNE of polypeptide-k tested in vivo through oral administration to streptozotocin (STZ)-induced rats provided a better antidiabetic activity.11 AND is a bioactive compound found in the Andrographis paniculata Nees plant with antidiabetic12 and antioxidant activities.13 AND is poorly soluble in water, which is associated with low bioavailability in its oral administration.1 The administration of oral AND can lower plasma glucose levels in STZ-induced diabetic rats, but the activity of which depends on the dose administered14 and the treatment applied.15 A compound with low water solubility generally has limited absorption and bioavailability that is usually controlled by the dissolution rate of the drug in the gastrointestinal tract. [...]efforts need to be made to increase the solubility. ASNE was obtained by mixing SNE with 15 mL of AND, based on a previously reported procedure.1 Animal study Animals Twenty-four adult's male Wistar rats with a body weight ranging from 200 g to 250 g at the beginning of the experiment were used in this current study.

Fourier transform infrared (FTIR) spectroscopy in combination with chemometrics of partial least squares (PLS) has been optimized for rapid determination of lard in a binary mixture with palm oil in a cosmetic lotion formulation. Lard, palm oil, and a binary mixture were extracted from matrix samples using liquid–liquid extraction, evaporated with a vacuum rotary evaporator, and the fat/oil yielded was further subjected to FTIR spectrometric measurement using attenuated total reflectance (ATR) as a sampling handling technique. The level of lard in the mixture with palm oil in the lotion formulation was quantified at frequency region of 1,200–1,000 cm−1. The PLS calibration model reveals good correlation between the actual value of lard (x-axis) and the FTIR predicted value (y-axis) with a coefficient of determination (R2) of >0.99. Furthermore, the classification between lotions with and without lard in their formulation was performed using principal component analysis using the same frequency region used for quantification. The developed method was subsequently used for analysis of cosmetic lotions commercially available in the market. All samples analyzed did not contain lard in their formulations.

This study investigated the diversity and antibacterial potential of marine endophytic fungi from Buton Island, Indonesia. This study focused on identifying fungi capable of producing bioactive compounds effective against Vibrio harveyi . 32 fungal isolates were obtained from various marine samples. Aspergillus terreus (WB 1-2) exhibited the highest antibacterial activity. The growth dynamics of these fungi were analyzed, emphasizing the importance of the log phase for secondary metabolite production. Environmental conditions and mechanical agitation were found to significantly influence growth and metabolite yield. These findings highlight the potential of marine endophytic fungi as sources of novel antimicrobial agents, suggesting promising opportunities for biotechnological and pharmaceutical advancements. This study underscores the untapped potential of marine fungi for the development of new antibiotics.

The incidence of atherosclerosis is characterized by an increase in the value of low-density lipoprotein (LDL) and a decrease in the value of high-density lipoprotein (HDL) as well as an increase in the total white blood cell count which can indicate the occurrence of atherosclerosis. This study used 18 rats which were divided into 6 groups of 3 each, namely a normal control group, a negative control group (CMC 0.5%), a positive control group (Simvastatin 20 mg/kg BW), and 3 groups given a sulfate polysaccharide isolate compound test material (dosage of 250, 50, and 10 mg/kg of body weight). The results showed that sulfated polysaccharide isolates had an effect in reducing white blood cells significantly between doses of 250 mg/kg BW and 50 mg/kg BW as well as reducing SGOT levels. Unfortunately it did not reduce the SGPT level. The results of the Mann-Whitney post hoc test showed that administration of sulfated polysaccharides at an optimal dose of 250 mg/kg BW reduced the number of foam cells in the atherosclerotic white rats' ( Rattus norvegicus ) aortas that were given a high-fat diet and had activity in reducing CKMB levels compared to other doses.

APE administration significantly improved the C[sub.max] and AUC[sub.0–t]/AUC[sub.0–∞] GLZ values in normal and diabetic rats (p < 0.05). AND significantly reduced the bioavailability of GLZ in diabetic rats with small values of T 1/2, C[sub.max], and AUC[sub.0–t]/AUC[sub.0] [sub.–∞] (p < 0.05). This combination can be considered in administering medications because it can influence the pharmacological effects of GLZ.
