The extracts were collected in 60 mL vials and treated 3 with sodium sulfate to remove any possible humidity. After filtration, the organic phase was concentrated to dryness in the Rocket Evaporator, dissolved in 200 μL of isooctane, and submitted to analysis by GC-MS/MS. The GC conditions are summarized below.

2 mL autosampler glass vial (Thermo Scientific™ Chromacol™ VAGK ISP: GC 2-SVW + 9-SCK(B)-ST1) using a Thermo Scientific™ Rocket™ Evaporator system [P/N 075904 (120 V) or 082766 (240 V)], shown in Figure 2B. The samples were analyzed using a Thermo Scientific™ TRACE™ 1310 Gas Chromatograph equipped with a PTV injector, a fused-silica
Chiral GC analysis was performed with a Trace 1310 gas chromatograph (Thermo Fisher Scientific) equipped with an Astec CHIRALDEX G‐PN capillary GC column (30 m×0.25 mm, 0.12 μm film thickness; Sigma‐Aldrich). Prior to GC analysis, sulfoxide samples in ethyl acetate were appropriately diluted in the same solvent and dried over anhydrous Na
Paclitaxel was validated at 2.0 µ g/mL, 5.0 µ g/mL, 10 µ g/mL, and 20 µ g/mL because of difficulty in av oiding precipitating out of the paclitaxel, possibly due to a reduc-
